Hello from Ottawa

#1 Post by miche » Mon Apr 16, 2018 2:56 am

Hello Folks -- New to this forum, but after the past hour or so perusing the many posts, it sure looks like there is lots of knowledge, experieince, and neat microscopes among you.

I've been bitten by the collecting bug and now have a number of 1960s black stands, and some 19th century brass ones.

One question to start (I'm sure I'll have more later): I now have some "live boxes", brass devices with a 1 x 3" brass base and a cylindrical bit in the centre. They either have no glass at all, or just one circular piece of glass. But to trap or hold critters, shouldn't there be two pieces of glass? How were these supposed to work?

Thanks.

Welcome, miche

Regarding the 'Live Box' ... have a look at Fig. 14 on this page:
http://microscopist.net/GardinerJB.html

Then, download Carpenter's book:

If the device has 'holding down' facility, it is often known as a 'Compressarium'
... A google search should bring-up many examples.

Some photographs of yours would be interesting to see.

Welcome miche, sounds like you have the same condition I have. I started with one a few months ago and now have 4.

Thanks for the welcomes.

Re MichaelG, please see the attached photo of my live boxes.

The url's were very helpful. My conclusion is that the second glass disk in each live box was intended to be very thin, like a cover glass, so they were very fragile and have not survived the ravages of time. So if I wanted to use one in its original role, where would I find glass disks with a correct diameter?

Welcome to the forum, Miche.

Yours does sound like compressarium.

Many lab supply companies offer various round cover slip diameters, such as 5, 8, 12, 15, 18, 20, 22, 25mm:

Google "round cover slip diameter" and you will likely find more.

Regrettably not, miche ... but I look forward to seeing your collection.

Although I don't own any, I have always found them fascinating: They seem to have inspired great ingenuity in their many makers.

... Meanwhile, I will share another link:

This is the device referenced on the 'microscope-antiques' page as being the most modern.
