them. We venture also, in conclusion, to draw the attention 
of our readers to the allusions to the researches of Klebs and 
Tomasi on the nature of malaria, as also to the notices of the 
experiments of Feser and Pasteur on the persistence of 
anthrax germs. Dr. Greenfield's work has yielded good 
results hitherto. We are encouraged to hope that he will 
deliver, and that we shall be instructed by, many of such 
courses of lectures, and that he will continue to appreciate 
the fact that, as Professor-Superintendent of the Brown 
Institution, he may prove a most important means of giving 
comparative pathology its proper position in medical and 
veterinary studies.

Quid sit pulchrura, quid turpe, quid utile, quid non.—H or. 
Parasites; a Treatise on the Entozoa of Man and Animals. 
By T. Spencer Cobbold, M.D., F.R.S., &c. 
The relation which Dr. Cobbold holds to the Royal 
Veterinary College as an instructor of our pupils, and the 
assistance rendered by him in respect of the helminthological 
department of this Journal, precludes our writing any¬ 
thing critical concerning his last contribution to the science 
he represents. This circumstance need not, however, 
prevent our pointing out the general design of the volume 
before us; and as regards both the manner in which the 
work has been done and the spirit in which it has been 
executed, we shall content ourselves with drawing atten¬ 
tion to the published statements of our medical and scientific 
contemporaries. 
As stated in the preface, the design of the book—or rather 
books, for two volumes of equal size are really compressed 
into one—was to bring to a focus all the more important 
facts and conclusions which the recent rapid advances of 
the science have established. In doing this the author has 
dwelt with especial care on the development of particular 
parasites, more particularly on those species which give
