from the shape which we have found most to answer the 
purpose.

“ Frankfort-on-the-Main, 26th January, 1857.” 
[We have inserted this communication at the request of 
Dr. Funck, but we cannot but feel that it is too late to make 
any alteration in the size or form of the slips used in England. 
The Microscopical Society have decided that the size of three 
inches by one is the simplest and most convenient. And as 
already thousands of preparations exist m this form, and 
thousands of slides are in daily use, both in England and in 
France, it is to be hoped that German microscopists will see 
the advantage of conforming to the same standard. Their 
doing so would much facilitate the international exchange of 
specimens, which is obviously so desirable.-—Eps. ]
