REVIEW — THE MICROSCOPIC ANATOMY OF 
spection — to the scrutiny of the microscope. Potent as micro- 
scopic machinery has of late years been rendered, and experi- 
enced as many have now become in the management of it, such 
phenomena as are thereby revealed to us being of a different order 
from those disclosed through chemistry, and yet, incidentally, 
reciprocally confirmatory one of the other, are in effect opening to 
us fresh fields of research ; — introducing us, in fact, into a new de- 
partment of science — MICROGRAPHY, a division of which, of the 
most importance to us, is “ The Miscroscopic Anatomy of the 
Human (animal) Body.” 
In an organized body, two orders of parts present themselves 
for microscopic examination, solids and fluids ; and since the for- 
mer proceed out of the latter, it is in accordance both with nature 
and reason that the fluids should be the first to be examined. 
“ Of the fluids themselves (however) it is difficult to determine 
upon any subdivision which shall be altogether without objection : 
perhaps the most preferable and useful division of them that can 
be made is into organized and unorganized :” such fluids being 
regarded as “ organized” as contain in them “ certain solid organ- 
ized principles, while those liquids which are compounded of no 
such solid matters, as essential portions of them, should be termed 
unorganized '.” 
“ In the first category, the lymph, chyle , blood, mucus, as nor- 
mal, and pus, as an abnormal fluid, would find their places, together 
with the milk and semen. The fluids of this class, it will be seen, 
belong especially to nutrition and reproduction, and admit also, 
naturally, of arrangement into two series ; in the first, those fluids 
which are concerned in the nutrition and growth of the species 
itself would be comprised, as lymph, chyle, and blood ; and in the 
second, those liquids which appertain to the reproduction, nutri- 
tion, and growth of the new species, as the milk and the semen, 
would be admitted.” 
“ In the second category, viz. that of unorganized fluids, the per- 
spirable fluid, the saliva, the bile, and the urine, as well as pro- 
bably the fluid of the pancreas, and of certain other peculiar glands, 
should be found.” 
Such is the plan and order of procedure of the work, the fluids 
first examined being 
The Lymph and the Chyle. 
Mr. Hassall has very properly cautioned any one about to exa- 
mine either of these fluids, to take care to collect it pure or un- 
mixed. “ It is a common error to regard and describe the contents 
of the (thoracic) duct, at all times, and under all circumstances, as
