ON MICBO-SUBLIMATION. 
BY HENRY J. WADDINGTON. 
Sublimation, especially in its relation to microscopy, has ately created so 
much interest that no apology is needed for a somewhat detailed account of the 
process and its results. It is a subject of which so little comparatively is 
known, and that little so imperfect, that it is quite worthy of being considered 
“ per se,” and independently of its practical utility. I may go so far as to say 
that what is wanted is some knowledge of sublimation itself, its applications 
following in due course. 
That many organic substances w 7 ere capable of volatilizing, when heated, has 
been known for some considerable time, but the methods used were not such as 
could afford a very definite result. The one in ordinary use of heating the sub¬ 
stance in a glass tube could not have been other than unsatisfactory, and hence
