HELMINTHES.

tempts an outline of all that is known respecting the Entozoa 
and their allies. A considerable number of the drawings are 
from the pencil of Professor Busk, F.R.S.; others are from 
original sources by the author. All those figures which are 
copied, as well as quotations, have their sources fully indicated 
and acknowledged. The bibliography alone extends over 60 
pages, yet comprises merely a record of all the more important 
memoirs which have appeared in the^English language. The 
work, as a whole, is the result of many years^ diligent labour in 
the field of Helminthology, and contains many facts hitherto 
unrecorded, some of which are believed to be of the highest 
practical value. 
The author divides the work into three sections. Part I., or 
Systematic HMminthology,^^ comprises a general account of 
the habits, structure, development, affinities, distribution, and 
classification of the Entozoa and their allies. It extends over 
141 pages. Part II., or Special Helminthology,^^ gives an out- 
line of the anatomical peculiarities, origin, mode of develop- 
ment, and propagation of the entozoa infesting man, with a 
particular account of the injurious eftects they produce, includ- 
ing a brief notice of the remedies employed in medical practice. 
This embraces 248 pages. Part HI., or Spurious Helmin- 
thology,^^ offers a brief account of the internal parasites of man 
not belonging to the class of Helminths, together with notices 
of various animal and vegetable substances reputed to have 
come from the human body. This takes up 31 pages. The 
remainder of the treatise is occupied by the bibliography, out- 
line of contents, description of plates, preface, and dedicatory 
letter to Mr. Busk *.

rich Mosler. Berlin, 1864. 8vo (pp. 89, with 2 coloured 
plates) . 
This pamphlet is chiefly interesting inasmuch as it carefully 
records the circumstances attending a successful feeding-expe- 
riment with the proglottides of T(snia mediocanellata. It also 
briefly notices two negative results, one from the administration 
of the joints of Taenia solium, and the other from the employ- 
ment of muscle-Trichinse in this relation. In all three in- 
stances the experimental animal was a calf. 
The author commences by pointing to the recognized resem- 
blances existing between the '^juvenile states of various measles^' 
and the common tubercles found in the different viscera of man 
* The author wishes to correct an error at p. 211, where the line no. 6 
from the top should read thus : — ‘^22 to 28 altogether, [i. e. 11 to 14] in each 
circular row.” The introduction of the words and figures here given in 
brackets is essential to render the description of the specific characters of the 
species correct.
