Transmission electron microscope

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.

This photograph shows NIAMS researchers looking at images of mouse muscle fibers on the confocal miscroscope's projection screen. The mouse muscle was being investigated as part of research on Pompe syndrome, a disease that causes muscles to deteriorate. The principal investigator for this work was Paul H. Plotz, M.D., who was Chief of the NIAMS Arthritis and Rheumatism Branch when the photograph was taken in the Light Imaging Section Core Facility in Room 1433 of Building 50 on the NIH Campus.

Manufacturer: Andrew Ross, London, UK (1843)

Artefact #: 2009.0088

Canada Science and Technology Museum

  

This microscope is a rare artifact for this period in Canadian history having been used by a woman amateur naturalist in the colonies, while accompanying her husband on his surveying and military missions. It is a portable microscope used by Caroline Bucknall Estcourt (1809-1886) (born Caroline Pole Carew), wife of a British officer, James Bucknall Bucknall Estcourt (1802-1855). Bucknall Escourt was posted to the Canadian colonies in the 1830s and 1840s. Caroline was an amateur naturalist of some note and a painter. Some of her graphic collections are preserved at the Library and Archives Canada including portraits, sporting scenes, landscapes and her journal.

 

It is also a significant microscope from 1843, incorporating one of the earliest commercial, portable achromatic lens systems (serial no. 68) made by the well-known instrument maker, Andrew Ross of London. Because of its colourful provenance and technical significance, it is one the most important optical microscopes in the collection.

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.
