lesions which necessitate immobility of the parts. In this case, and occa- 
sionally in the heart itself, in addition to the transformation of the muscular 
fasciculi above described, adipose tissue accumulates between them, and by 
compressing their substance adds to the rapidity and completeness of the 
transformation. In such cases the muscles are of a pale yellow colour, 
yielding on section large quantities of oil, while they preserve their usual 
form and fibrous look. J have seen all the muscles of the lower extremities 
so affected. Occasionally, while some muscles exhibit this transformation 
in its last stage, others close beside them present their normal red colour, 
so that the limb on dissection resembles the alternate red and fatty streaks 
of bacon. In this case the degenerated muscle has the whole of its fasci- 
culi transformed into adipose cells, with nuclei. 
“Tn involuntary muscles fatty degeneration may also be observed, al- 
though it is by no means so common as in voluntary ones. In this case, 
oily molecules are deposited in the elongated fusiform cells of which the 
texture is composed, which by their pressure on the nucleus cause its disap- 
pearance. Whether the distended pregnant uterus shrinks to its normal 
proportions after delivery wholly in consequence of such a degeneration 
(Heschl) is a point not yet determined in pathology. But there can be no 
doubt that many of the greatly enlarged fusiform cells of the organ, do be- 
come more or less crowded with fatty granules.” (pp. 226-228.) 
In his preface, Dr. Bennett states that he has “been long 
persuaded that mere description of morbid appearances, and 
especially of those that are made visible by means of the 
microscope, communicate only feeble or imperfect ideas to 
others.” He has accordingly abundantly illustrated his work 
with wood-engravings, of which there are nearly five hundred 
in the volume, mostly devoted to microscopic appearances. 
This work will, we are sure, greatly enhance the reputation 
of Dr. Bennett as a practical pathologist, and find its way to 
the study of every scientific practitioner of medicine. 
Illustrations of the Constituents of Urine, Urinary Deposits, and 
Calculi. By Lionet 8S. Beatz, M.B., F.R.S. London:

Tue object of Dr. Beale in preparing these illustrations 
has been to place in the hands of medical students and prac- 
titioners of medicine, at a moderate price, a series of correct 
representations of the various deposits found in healthy and 
morbid urine, as well as of salts held in solution, or formed 
by chemical re-agents in this secretion. The work contains 
thirty-seven plates, with upwards of one hundred and seventy 
figures and accompanying letter-press, and seems well 
adapted to secure the object Dr. Beale had in view in its 
publication. It embraces almost all possible forms of objects 
that could be presented to the student in connexion with the 
urine. It is also accompanied by a frontispiece and wood- 
cut, illustrating the anatomy of the kidney,
