One of two ornate silver microscopes made by George Adams (1709-1773) of Fleet Street, London, for King George III (1738-1820). It is based on the 'Universal Double Microscope', described by Adams in 1746. It is made of brass and steel, covered in beaten silver.
Photographed in the Science Museum, London, through its glass case.

Description(Physical Details): Brass-plated light microscope in wooden carrying case with lens cases. Box is simple, light-grained wood with heavy iron handles and no significant ornamentation, has a top-opening hinge mechanism, and a key lock which does not function completely. The inside of the box is purpose-built to accommodate the microscope and two wooden enclosures for holding swappable lenses, with metal slides integrated into the side of the box to keep them in place. The two lens holders have three empty brass cylinders which presumably held lenses at one point, along with one 5mm eyepiece lens. The microscope itself is simply styled, with brass plated objective lenses and body and heavy steel base. The eyepiece is 10mm and swappable, attached to the body with a threaded screw-type fitting. The objective lens has fittings for three lenses, all swappable, and is fitted with 4mm, 16mm, and 19mm attachments. The focus knob has measurement values ticked in increments of 10 with ticks at each individual number from 0 to 100. Stage is affixed with a steel arm which can move approximately 270 degrees, with a mirror fitted underneath to feed light into the viewing area. Stage can be lowered and raised slightly with the use of a knob fitted underneath the base plate, and could also be entirely detached. Base of instrument is stamped "Lyons & Co. Ltd., New Orleans" as well as "Bausch & Lomb Optical Co., Rochester."

Taken with a Microscope and attached DSLR camera... I made them into HDR's but otherwise did not feel like editing them. Sorry.
Microscope now activated. For use to allow customers quick and low-cost access to study research results while the payload is still onboard the space station.
This a freshwater ostracod taken from our small aquarium. Ostracods are small crustaceans (like crabs, shrimp, etc..) but they are a bit unusual in that they have a bivalve shell similar to clams and oysters. For some reason these little buggers are becomming more and more fascinating to me. Tammy thinks I may be nuts though.
As we consolidated two tanks into one, my chief concern was with the shrimp (a species of freshwater/marsh shimp) and the ostracods. The ostracods have only ever shown up in the smaller tank for some reason. I collected at least 250 ostracod, leaving behind sevral hundred more, before we broke down the smaller tank.
While adding the ostracods to the larger tank we all were able to get a good demonstration of the strengh and value of the ostracod shell. The larger tank is home to some tetras and corydora catfish. As I put the ostracods in with a pipette, several of the fish tried to eat the ostracod. They chewed and chomped, then spit the ostracod back out into the water column, then tried again. Finally all the fish gave up, spitting the ostracods out one final time. The shells appeared to be clasped tightly together, no appendages hanging out, but otherwise appeared unharmed. After hitting the sand, the ostracod remained motionless for about 20 seconds. Suddenly, one at a time, they began swimming, in a their characteristic drunken motion, off the sand and found refuge on a piece of submerged driftwood.
The ostracod population in the tank is highly cyclical. For about 6-8 months out of the year they are abundant, grazing on microscopic algae on the glass, plants, wood features and in the upper layer of the soil. Then suddenly there will be none visible anywhere. It makes me think that they came originally from a vernal pool. One piece of wood in th tank came from a vernal pool area and is a likely candidate as "invasion" vector.
Truth be told though, I don't mind this invasion at all.
