ACCOUNT OF A CALCIFIED TESTICLE OF A RAM. 45 
that, when the specimen was shewn to a distinguished anatomist 
(without any intimation as to its history), he at once suspected 
its true nature.” The fragility of the substance having pre- 
vented the preparation of a section sufficiently thin to be seen 
by transmitted light, the surface of a small piece, sawn off from 
the testicle in a transverse direction, was examined under the 
microscope, with reflected light, and an inch power, magnifying 
100 diameters. We prefer giving to our readers an idea of 
the appearances presented by this interesting specimen in Mr. 
Gamgee’s words. 
“The tubules are seen to be completely filled by uniform 
earthy deposit of a dead white colour ; many of them are 
studded with a few small holes. The circumferential border of 
the tubes is darker than their interior. Their shape varies ; 
some of them are perfectly circular, others oval or elliptical ; 
and others are much elongated, and bent in the form of a 
crescent. This difference in shape, doubtless, depends upon the 
relative direction in which the tubes were divided ; some being 
sawn directly across, others more obliquely, and a few length- 
ways, i. e., along their long axis. The diameters of the spherical 
tubes average from to of an inch ; a few, however, only 
measure of an inch across. Many of the tubes are in 
close apposition, while others are separated by a considerable 
quantity of intermediate substance, of a yellowish colour and 
apparently granular texture, interspersed with numerous small 
holes. In some parts this material is wanting, and the tubes 
are separated by irregular chinks.” 
In systematic works on pathological anatomy, the author 
found no mention made of diseases affecting the testicle similar 
to the case in question ; but his attention was directed to a 
drawing in Dr. Carswell’s extensive and valuable collection at 
University College, by Dr. Sharpey, the eminent Professor of 
Anatomy and Physiology in that institution ; whose lectures 
we are glad to know have, in the last few years, been frequented 
by veterinary students, who, in the middle of the nineteenth 
century, not being taught physiology in their own school, have 
set an example worthy of imitation, by endeavouring to acquire 
elsewhere a knowledge of its truths. 
Dr. Carswell’s figures represent the process of calcification in 
the testicle of a goat, at a much earlier stage than the case 
described by Mr. Gamgee; and although that eminent patholo- 
gical anatomist had not recognised the hard wiry vessels as the 
tubes of the testicle calcified, there can be no doubt that such 
was their nature.
