THE MIcROSCOPE. 45 
life. It is not a dull account of dry facts, letters and journals ; 
but rather is it a narrative of a life marked by rare coherence and 
unity of aim; a life that cannot fail to stimulate and encourage 
others. It isa work that any of our readers will be delighted 
to read. 
MICROSCOPICAL TECHNOLOGY. By Carl Friedlaender. Translated 
by Dr. S. Y. Howell, of Butfalo, N. Y., and published by G. P. 
Putnam’s Sons, New York, 1885. Small 8vo. 250 pp. 
In our December issue we reviewed this same work trans- 
lated and published by different parties. 
Both. editions claim to be “ translated with the permission 
of the author from the second enlarged edition.” The work 
contains methods of preparing tissues and fluids, and an account 
of reagents used in general work. If two such large houses are 
{o push the same treatise on some microscopical subject it is to 
be regretted that the treatise is not more worthy of their hire 
than the one before us. This is good so far as it goes, but is 
elementary and limited in character. 
AMERICAN MEDICINAL PLANTs. By F. C. Millspaugh. Published by 
Boericke and Tafel. New York and Philadelphia. Fascicle III. 
This is the third time we have had the pleasure of noticing 
this valuable addition to our Materia Medica. The plants are 
all drawn and colored from nature, by Dr. Millspaugh, and the 
lithographers have reproduced the plates with fine effect. 
It must be an expensive undertaking for the publishers, and 
it is to be hoped that our American botanists, and all interested 
in medical plants will give them ample support. They certainly 
deserve it, as does the hard-working author. 
ESSENTIALS OF VACCINATION. By W. A. Hardaway, M. D. Small 
8vo. pp. 150. 1886. Published by J. T. Chambers & Co., St. 
Louis, Mo. 
The author gives us a compilation of facts relating to vac- 
cine inoculation and its influence in the prevention of small- 
pox. Abnormal complications and modifications of vaccinia ; 
re-vaccination and many other interesting subjects are discussed. 
The author believes that persons should be re-vaccinated as 
often as there is any danger of infection, “‘ even if a few months 
only had elapsed from the date of the previous inoculation ;” 
and that as often as once every five years anyway.
