older worker is by no means overlooked. The 
more thoroughly studied substances, such as 
ego- and serum-proteids with their crystalline 
forms, are taken up at length; and the muscle 
proteids are presented in the light of v. Firth’s 
work. To the physiological chemist who has 
occasion to refer frequently to recent investiga. 
tions on the nucleoproteids and their derivatives, 
the careful summary of research in this field of 
work will be found most helpful. Thirty pages 
are devoted to the chemistry of hemoglobin, 
and the chapter on the albuminoids is fairly 
exhaustive. 
The volume is appropriately dedicated to the 
memory of W. Kihne.

Treatise on Hygiene. By J. LANE NOTTER. Sec- 
ond edition. P. Blackiston’s Sons & Co. 
1900. © 
This is the second edition of the well-known 
book of Notter and Firth, which itself was 
founded on the still earlier treatise of Dr. A. E. 
Parkes. 
It is a very comprehensive work, contain- 
ing nearly eleven hundred pages, and treating of 
a very wide range of topics, such as, for instance, 
water, air, food, heating, ventilation, clothing, 
exercise, construction of houses, vital statistics, 
and military and naval hygiene. 
The book as a whole is excellent, the material 
is well selected, and the views thoroughly 
modern. Treating such a wide range of sub- 
jects as the authors do, they must necessarily 
give frequently the opinions of others rather 
than their own, and this causes at times, where 
opinions differ, a lack of authority. Ina few 
places remains of earlier editions crop out ; thus 
under malarious soils no mention is made of the 
mosquito, but in another portion which is de- 
voted to malaria the relation of the insect to 
the disease is fully stated. 
In some places important omissions occur: 
thus in the preservation of milk cold is hardly 
alluded to, yet it is almost as important as 
cleanliness. The number of bacteria considered 
suitable in milk, 400,000 per ec., seems very 
high. Taking the book as a whole, it is one 
that can be thoroughly commended to those

SCIENTIFIC JOURNALS AND ARTICLES. 
THE Journal of Comparative Neurology for 
December contains the following articles: ‘The 
Giant Ganglion Cells of Catostomus and Core- 
gonus,’ by J. B. Johnston, West Virginia Uni- 
versity. The author figures and describes suc- 
cessful Golgi preparations of these transient 
nerve cells and compares them with the sensory . 
cells in the spinal cord of Amphioxus and Pet- 
romyzon, whose fibers reach the periphery with- 
out effecting relations with cells of the spinal 
ganglion. It is suggested that they are belated 
neural crest cells which failed to migrate into 
the spinal ganglia. ‘Arrangement and Termi- 
nations of Nerves in the Gisophagus of Mam- 
malia,’ by Lydia M. DeWitt, University of 
Michigan. Investigations on the cat and rab- 
bit by the intra vitam methylene-blue method. 
The following types of nerve termination are 
described: typical motor and secretory fibers 
from sympathetic ganglia of Auerbach’s and 
Meissner’s plexuses, motor fibers from the ven- 
tral horns of the spinal cord for the striated 
muscle fibers of the cesophagus, sensory termini - 
in the mucosa from cells of spinal ganglia, and 
other sensory fibers, apparently wholly con- 
fined to the sympathetic nervous system. ‘ The 
Vibrissze of certain Mammals,’ by J. Franklin 
Messenger, University of New Mexico. The 
innervation of the hair follicles is figured and 
a peculiar erectile vascular pulvinus is described. 
‘The Ophthalmic and Eye Muscle Nerves of 
the Cat Fish (Ameiurus),’ by I. S. Workman, 
Denison University. The cat fish is shown to 
resemble other teleosts in the absence of a r. 
ophthalmicus profundus. The nerve so named 
by some anatomists is the r. ophthalmicus super- 
ficialis V, to which are added facialis fibers for 
terminal buds on the top of the head. The eye 
muscle nerves show a ganoidean arrangement. 
‘On the Homologies of the Chorda Tympani in 
Selachians,’ by H. A. Green, Denison Univer- 
sity. The selachian. types examined exhibit a 
pre-spiracular nerve, in addition to the r. pala- 
tinus and the true pre-trematic ramus for the 
pseudobranch, which runs down between the
