PHYSIOLOGY or THE CrrcuLaTion.*—In this useful work the 
author has aimed ‘‘ at producing a ‘comprehensive view of the cir- - 
culation as it exists in the lowest vegetable and highest animal 
forms.” He has ‘endeavored to prove by a variety of arguments 
that the circulation, whenever and wherever found, differs less in 
kind than in degree; that fluids may move in living tissues with 
or without vessels and hearts ; that the circulation in an aggrega- 
tion of vegetable cells is essentially the same as that which occurs 
in the tissues of our own bodies. As a chain is composed of 
links, all of which are formed on a common type and fit into each 
other, so the circulation in the lowest vegetables and animals 
gradually develops into that of the higher, until we reach man 
imself; the circulation in the one being a as perfect as 
in the other.” 
_ BULLETIN OF THE CORNELL Untvenstry. +—The first two num- 
bers of this new periodical, a credit alike to the university and 
the officers, contains a report of a reconnoissance of the Lower 
Tapajos river, by Professor C. F. Hartt, and a finely illustrated 
paper by Mr, O. A. Derby on the Carboniferous Brachiopoda of 
Itaittiba, Rio Tapajos, Brazil. We hope the patrons of the Uni- 
versity will sustain this valuable publication. 
Manvat or Meratturey.{—The author of this excellent manual 
was a student of Dr. Percy, the distinguished metallurgist, from 
_ whose work the present one is in part compiled. It will evidently 
prove, as the author hopes, a useful auxiliary to the more volumi- 
nous works on this subject. It is amply illustrated.
