Re: More on A.pellucida

Not entirely sure, might have been the 1.6 NA (!!) exotic immersion
one, something like monobroomnaphtalene immersion directly on an
uncovered specimen. Will dig out the Neuhauss book tonight.

I was incorrect re identification of the A.pellucida image referenced in a
previous post, i.e. it may have been by Neuhauss.

On going back over some old notes, it appears that this image is from
W.B.Carpenter's book "The Microscope and its Revelations" published in
1891. It is accredited to Prof. Van Heurck, a rather well known
microscopist!

This image most probably originated with Martin Mauch at :www.baertierchen.de

Regardless, the definition of the dots within the right-hand section of
this mount is startling - in fact it's hard to believe.

It would be real interesting if anyone can dig out information on the
equipment and illumination technique used by Van Heurck.
My notes indicate a Zeiss objective (presumably 100x) with NA 1.4 - a very
nice piece of glass (hand ground) back in the 1890s.
