When a male wants to attract a female he does what is known as infrasound mating call. This activity involves bellowing in a low frequency call, that is inaudible to humans. With their head and tail raised over the water surface while their midsection is partially submerged, the water over their backs shoots up like a fountain display from the vibrations produced from the low frequency bellow. This is known as the "Water Dance of the Caiman". Our guide said that they only do this "water dance" call once a day. We were lucky to see it three times...all early in the morning.

Created in 1928 for the home of Marjorie Merriweather Post, this window is located in the Tutor mansion's Great Hall, now the administration building at the C.W. Post Campus of Long Island University. The window is crafted of 10 intricate sections of leaded glass set into a plaster and stone frame and featured the Post family crest and nautical scenes. The university crest was added to the lower midsection of the window in 1979.
The sight arm on a Mance Heliograph[1] is used to attach either the foresight ("jointed sighting rod") or the secondary ("duplex") mirror to the base of the primary gimbaled mirror. To see how the sight arm fits in with the other parts of the Mance heliograph, see the 5" Mance Mark V diagrams at flic.kr/p/ecRWyr for the sighting rod and flic.kr/p/2pAtytv for the duplex mirror. For complete instructions on the use of a Mance heliograph, download the 1922 manual at: www.prc68.com/I/pdf/1922_08_Heliograph_5in_MarkV_med.pdf For much more information about Mance heliographs, visit the British Heliograph Club on Facebook at: www.facebook.com/groups/776510812960897
In the photos in this album, the top end is the "outboard" end, and the small hole there clamps onto the rod at the base of the foresight or secondary mirror. The large hole at the bottom clamps onto the base of the primary mirror. The clamping screws at the top and bottom are used to tighten the clamps securely.
Mance invented his heliograph in 1869, but took over a decade to adopt the idea of a sight arm for his heliograph. Mance's early design, shown in his patent applications filed in England on October 3, 1874[2] and in the United States of America on February 25, 1876[3], and depicted in the August 1876 British Army Signalling manual[4], used a separate long sighting pole set up 30 feet in front of the instrument[5]. By the time of the 2nd Afghan war in 1879, Mance had traded in the long sighting pole for a short sighting rod mounted on a separate tripod 3 ft in front of the mirror tripod[5], but still resisted attaching a sight arm to the primary mirror. In contrast, Begbie's sun-flashing instrument is shown in the 1876 British Army Signalling manual with a sight arm, and the Roorkee heliograph used in the 2nd Afghan War during 1878 and 1879 used a sight arm 16 inches long[5].
However, the 5" Mance Mark I adopted in 1882, and all subsequent Marks, did have a sight arm attached to the base of the primary mirror, interchangably holding a foresight or second mirror in front of the center of the primary mirror.
This album of photos shows top, bottom and side views of sight arms from four versions of the 5" Mance heliograph:
- an early 1880s(?) 5" Mance Mark I (Mark I defined in List of Changes §4147, date of order 11 Sept. 1882)

I don't have sight arms from the Marks III and IV to photograph, but the Mark III arm is very similar to that of the Mark II, and that of the Mark IV to the Mark V, with the peculiar variation that the rear clamping screw for the Mark IV is in front of the tripod, rather than behind it, as in all other Marks. An example of the Mark IV sight arm can be seen at Wikimedia Commons[6].
The sight arms of the Mark I and Mark II folded up at a hinge, and when deployed, could be locked in place by a screw in the Mark I and a spring clamp in the Mark II (and III). In contrast, the arms of the Mark V (and IV) were rigid.
Mark I: The Mark I sight arm has a tapering arm that is "lightened" by four spaced openings, giving it a slight resemblance to a stepladder when viewed from above. Those openings are larger on the underside. The rear clamping screw has a longer shaft than those on the Mark V, and the slot at the outboard end has a "strain relief hole" drilled at its inner end, unlike the other examples. The distance between the centers of the small and large holes is roughly 8.7 inches. Note that this example is painted black, and the design was retired in 1885. Since this 1880s sighting arm and the 1890s sighting arm are painted/finished black, I believe that Mance heliographs from the 1880s on were originally painted/finished black, and that examples of Mance heliographs in plain brass are a combination of wear and deliberate polishing for aesthetic reasons.
Mark II: The original clamping screws are missing in this 1890 example, replaced by wing nuts, and a broken bit of rod is clamped in the outboard end, so those bits should be ignored. The changes from the Mark I are described in List of Changes §4941 as: "The joint of the arm is made rigid by the introduction of a snap-action catch in lieu of a screw.
The jointed arm has been fitted with two small projections which prevent it from striking the mirror when doubled up". These changes in the sight arm are the only changes to the heliograph itself between the Mark I and Mark II that are described in the text of the List of Changes entry. However, the List of Changes comment that "A pattern has been sealed", and there might be other small changes in the pattern besides those described in the text, such as the absence of the strain relief hole. Note also in the side views that the thickness of the midsection of this Mark II sight arm is less than that of the Mark I example.
The switch from the brass hinge locking screw to the spring clamp are most easily seen in the photos of the tops and undersides of the sight arms. The two small projections (hinge stops) are most clearly seen in the side view of the sight arms.
Mark V 1909: The length of the Mk V sight arms are less than those of the Mk I/II, with the distance between the centers of the clamping holes reduced by about 1 inch - from 8.7 inches to 7.7 inches. There is no hinge, the arm is narrower, and it has a "T" cross-section. The manuals say to mount the arm with the vertical rib on the underside, and that's the way one sees it in period photos, but one often sees the arm mounted "rib up" in museum displays and auction listings. The heads of the clamping screws are hollow/skeleton, vs. the solid heads seen in the Mark I example.
Mark V WW2: The hollow/skeleton clamping screw heads of the 1909 model have returned to the solid heads, and the smooth black paint/finish of the other three examples has been replaced by the rough "wrinkle" paint invented in the late 1920s. Those are the only changes from the 1909 model that I see.

[1] From Wikipedia: en.wikipedia.org/wiki/Heliograph "A heliograph (from Ancient Greek ἥλιος (hḗlios) 'sun' and γράφειν (gráphein) 'to write') is a solar telegraph system that signals by flashes of sunlight (generally using Morse code from the 1840s) reflected by a mirror. The flashes are produced by momentarily pivoting the mirror, or by interrupting the beam with a shutter." Henry Mance invented the British Mance pivoting-mirror heliograph in 1869. Mance heliographs were used by the British in combat from at least the 1877 Jowaki Afridi expedition in Afghanistan through the June 6, 1944 D-Day Normandy landings in WW2.

MANCE, Henry Christopher, of 5, Magdala Terrace, Manor Road, Brockley, in the county of Kent –"Improvements in apparatus for telegraphing by means of reflected light."
This Specification describes arranging a mirror in such manner that flashes of sun light may be reflected with such ease, quickness, precision, and accuracy, both as regards direction and duration, as to afford a ready means of communication between stations however remote (provided the rotundity of the earth or other obstacle does not intervene). The apparatus is specially adapted for use between changing positions, and therefore for military purposes in the field. The apparatus permits of the use of the Morse alphabet, which as the best code of signals extant is usually employed.

"When the heliograph was in its infancy, a sighting rod was set up about 10 yards in front of the instrument, and fitted with a metal stud which slid up or down until truly aligned with the distant station. In communicating, the flash was kept playing on the stud. This sighting rod was abolished in favour of a tripod, which serves to support quite a new form of sighting rod (or, when the position of the sun demands it, a reflector which is ingeniously adapted to serve also as a sighting vane). This second tripod is placed about 3 feet from the signalling mirror tripod; being made to interlock, both can be carried when packed as easily as one. But the instruments now issued to regiments in India are provided with a supporting arm which dispenses altogether with the second tripod. This arm, about 16 inches long, is clamped to the base of the instrument and serves to support the sighting rod, or when occasion requires it, the reflector. The points for and against a supporting arm may be summed up as follows: ..."

" Mr. Goode : I should like to ask Major Hamilton a question. He has spoken as if the Roorkee instrument and the Mance were two distinct things ; would he kindly explain in what respects they differ ?
Major Hamilton : The Mance instruments which we had were the 6-inch instruments similar to those now in the room, and some 10-inch instruments with heavier tripods. In each case two tripods were used. The Roorkee pattern that I spoke of is of a different pattern, having only one tripod with an arm. The whole machinery was very much lighter. I never weighed one against the other but the Roorkee pattern was of lighter construction ; it was very handy, and on the whole I think worked better than the other. The springs were more satisfactory in their working.
Mr. Goode : I asked in what respect they differed in principle or in construction.
Major Hamilton : The general principle of the two was the same.1 In the Mance heliograph there were two tripods, one for the sighting rod, and the other for the heliograph. while the Roorkee pattern had but one tripod, and the sighting rod was at the end of an arm.
...
1 In order to avoid misapprehension it should be stated that the Roorkee instrument is a modified form of the Mance heliograph.—Ed."

Are you ready to maximize your workout with a faja style waist cinching garment the workout band is an ann cherry waist cincher that you wear anytime you're going to be active. Take it to the gym or for a run outside and let it add impact to your healthy lifestyle routine. Here's how it works. You wrap the band around your midsection. This action creates compression in your core, stimulating thermal activity and ramping up perspiration. This process allows toxins and impurities to exit the skin, while mobilizing fat cells.
So I just realized that all my previous pictures have the annoying elastic band concealing the midsection of the pictured pens and since I have a Factory display tray I thought I would take these pictures to ameliorate my OCD. I was going to wait until my other 2 pen acquisitions arrived but OCD is a terrible affliction which is difficult to resist! Laziness however successfully suppressed my initial inclination to again list the various pens so you’ll just have to look at my other posts if you really need to know the various models pictured.

It was the warmest game of the season for the Ravens so far...and a strange blow to the midsection caused Brett to have some problems catching his breath. The big guy has to start taking care of himself, so he can take care of the team easier.

Turmeric Forskolin is a propelled weight reduction recipe that has been ended up being useful for individuals who wish to dispose of their fat. it's been demonstrated through different investigations that Forskolin assumes a vital part in consuming the muscle versus fat, in the principle assaulting the midsection fat. Midsection fat is that the most extreme half to instigate free of. On the off chance that this item causes us to fathom our hardest assignment, so what's the issue with it.
Rapoport and Sachs still at cruising weight. That would be old news in about 30 minutes from this point. After that the weight collected around our midsections at an alarming rate.

The temporary bridge is about done. You can see the four scaffolding towers that will support the midsection, which will have to be raised and lowered to allow boat traffic through.
This is a drawing of a chicken embryo at 24 hours old. At this point, the spine is already forming. The bumpy looking things in the midsection of the drawing are actually part of the spine beginning to form. This image is exactly what a human embryo would look like during this stage. In just a matter of hours there will be many more changes in the embryo.
I was taking shots of gulls flying just to sharpen my BIF skills, never realizing until now that it was of a gull that I had never ID'd before. Apparently, they summer in the midsection of the Continent and winter around the East.
Tower and Steeple
As originally designed and built, Independence Hall had no tower or steeple. These were added around 1750. The wooden steeple had rotted by 1773 and was removed in 1781. In 1828, the city hired architect William Strickland to restore the original steeple. Strickland deviated from the original design, incorporating a clock and additional ornamentation. A recent restoration of the steeple revealed Strickland’s modern engineering principles.
