his observations upon this most important organ : as my 
only object in what I have already stated, is to mention, that 
the fibres of which it appears to be made up are composed of 
globules. 
Upon mentioning Mr. Bauer’s observations on the brain 
to some of my friends, I was referred to the Supplements to 
the 4th and 5th editions of the Encyclopaedia Britannica,* in 
which the opinion of the brain being composed of globules 
is noticed* I find, upon making such reference, that there is 
not enough stated respecting the anatomy of the more minute 
parts of that organ, to supersede a farther investigation of 
its structure, as will appear from the following extracts. 
“ It (the brain) has been subjected to very minute micro- 
scopical observations by PROCHASKA.-f When he took a small 
portion of it, either from the brain proper or the cerebellum, 
and spread it on a thin plate of glass, so that it became pellu- 
cid, and then examined it with a powerful microscope, he 
found that it resembled a sort of pulp, consisting of innume- 
rable globules, or particles of a roundish form. A little Water 
added to this pulp, divided it into a number of flocculi ; but he 
observed that each flocculus was still composed of a number 
of globules. He very rarely found one globule by itself, or 
even two, floating in water, apart from the rest. Maceration 
in water, even for three months, was insufficient to separate 
them from each other. He concluded, therefore, that they 
were united by means of a very delicate and pellucid cellular 
substance. The globules, he observed, were not all of the
