182 THe Microscope. 
and put this turn-table to such nocturnal uses. The only 
trouble our Eastern friend would experience in using this in- 
strument would be: the table turns so easily on its pivot 
that once started it is very difficult to stop. In fact when 
thoroughly under way, Mr. Griffith says himself, it frequently 
takes a mount-o’-cat or a cat-a-mount to stop it. 
The other piece of apparatus is a microtome that, like 
many others, can be used either as a freezing-microtome or as 
the more common microtome. It will cut sections to perfection 
as thin as the sv part of aninch, and it can cut one-half as thin 
as that. 
The instrument is made in Germany and costs, with duty, 
about forty dollars. It is owned by Dr. S. Duffield, of Detroit. 
The doctor is a very fine microscopist and, as a result of his 
labors at home and abroad, has a valuable collection of mounts. 
We hope to meet him and his microtome at the ‘ working ses- 
sion” of the Rochester meeting.

A CONUNDRUM. 
Who is to be our next President ? 
As nothing like politics is ever known to enter a body of 
scientific men, therefore the above question must refer solely to 
the late meetings at Chicago instead of the coming meeting at 
Rochester.

REWARD OFFERED. 
Lost.—Reward Offered—A copy of ‘“Heitzmann’s Micro- 
scopical Morphology ” will be given for any information that 
will lead back to the ranks of microscopical science a 
man who was seen to come from the printing house of J. H. 
Vail & Co., of New York,in 1883. He had on a garment of an 
intranuclear and intracellular network of minute fibrils and 
started in a direction that would lead to the overthrow of the 
cellular doctrine and the upbuilding of a new bioplasson the- 
ory. As nothing has been heard from this person since objec- 
tives have been properly adjusted and accurately focussed, the 
above reward is offered.
