measure, as corresponding books of their times, the difference in 
new matter or in newly developed points, as shown by an exam- 
ination of the Jatter, is.a satisfactory commentary on the progress 
of structural science during this brief period. 
The second volume of the Mikroskopische Anatomie is pub- 
lished before the first, a mode of proceeding which we do not 
like, but which is becoming not uncommon abroad. It of course 
enables the investigator to put that portion of his labors before 
the world which have been finished, and so far is very good, but 
we question if the work, as complete, is not thereby delayed. 
This second volume is devoted to special histology, and treats 
of the essential structure of the skin; or rather, more comprehen- 
sively, of the cutaneous system, of the bones, and the nervous sys- 
tem; these subjects are included in the first half. The first part 
of the second half, and all published that we have seen, treats of 
the digestive and respiratory organs; and when it is borne in mind 
that the histology of these two subjects occupies 900 pages, an 
idea will be entertained of the comprehensive manner in which 
they are taken up. ‘The limits of our prescribed space make it 
wholly out of the question to review such a work, for each of its 
subjects presents enough of new matter originally brought out, 
for a special examination. We shall be well content if we suc- 
first described its peculiarities, general and intimate, as a tissue of 
its kind or genus; then follows the details of its structnral analy~ 
innervation, its nutrition, and its connections with surrounding 
parts. You have then, Tissue: its structure, general, special, 
anatomy and physiology have been too much inclined to treat 
the human subject with its details as though its physical relations 
to the inferior animals, were as dissimilar as those of its mind, 
They would seem to forget that, zoologically, man is an animal,
