Thanks for these images. I have seen these myself once or twice. It is a great mystery to me that Leidy, the first and foremost of American parasitologists (and protozoologists) clearly saw this and drew them: See: http://www.xmission.com/~psneeley/Personal/Fwr09P.htm And even all but said "These ar...

Thanks for the comparison images.

365 nm is just beyond 'Vivid Violet' at 380 nm (see http://en.wikipedia.org/wiki/Violet_(color)) I was wondering if anyone had tried violet in the visual range (e.g. vivid violet) in this kind of experiment?

I'm sure by now most have seen this, but if not, it is a real treat:

See http://www.bairbrepaws.com/psneeley/Fwr42P.htm

These are always found in colonies? I've actually never seen a colony, but I will keep looking.

Ooops. I think that link got deleted when Tom posted the review - I didn't notice (sorry).

You might want to try the downloadable PDF first, since it is really just $3.78 (well, based on the exchangae rate a few days ago) and you may find you don't need a printed copy.

The illuminator, alone, is worth $20+. These older 'Black' upright, monocular models are 'old fashioned', but very, very good. They typically have stunning optics (in the central FOV, they are not usually Plan optics) and rock solid mechanics. No doubt this will make a fine scope for photomicrograph...

BTW, that looks like an AO Spencer Starlight attachable substage illuminator -- Cat# 612 or 618???

First, I'm not knowledgable on B&L, but I do know that this document: http://xmission.com/~psneeley/Personal/HowOldIsThatMicroscopeIntheWindow.pdf Answers your question. The letter 'R' as in 'RDxxxx' means that the scope was built in 1954. 'D' refers to 'Class 31' which simply means 'a microscope'. ...

Yes . . . somebody's spent way too much time :? But, if you have problems getting the blue book to download, tell me how to send you those pages and I will -- no problem -- I can send them as jpeg if needed. They tell all about your scope and answer all the questions above, etc. That is a fine scope...

Ken,

Go to this site: http://xmission.com/~psneeley/Personal/Microscope.htm

and download the AO Blue Book (yes, it's big, but it's good). Now take a look at pages 132 to 134.

Hope this helps,

Steve

I would say so.

See Plate #42 at: http://xmission.com/~psneeley/Personal/Leidy.htm Click on the thumbnail and look at it at full resolution.

What a beautiful image you have taken.
