PARTIAL DIVISION OF TENDO PERFORATUS, ETC. 155 
which divided tendons heal, fully justified Mr. Bray in under¬ 
taking this case. 
In the few remarks I have to make, I shall first allude to 
the specimen, and through it judge as to the probability of 
the case terminating favorably, or not. 
The parts sent to me consisted of portions of the perforatus 
and perforans tendons, with the intervening new material, 
which had been thrown out for the reparation of the lesion. 
Altogether it measured about seven inches in length. The 
accidental division of the tendons seems to have taken place 
about three inches above the sessamoid bones, which would 
be a little above the bursa common to these tendons and the 
bones just alluded to, and which fortunately were not in¬ 
terfered with by the accident. The outer surface of the 
specimen, including portions of the original tendons and 
the whole of the new material, gave no evidence that diseased 
action was going on. On the contrary, it was covered by 
a sort of fibro-cellular sheath, which appeared to be quite 
healthy. The cut ends of the tendons were slightly en¬ 
larged, and a little reddened, due partly to increased vascu¬ 
larity and partly to stain, the results of effused blood at the 
time the wound was inflicted. The new substance, which 
encroached a short distance upon the outer surface and 
between the original tendons, was quite as large and as 
abundant as could be desired, for the purpose of efficient 
reparation. (I have seen instances w T here the effused matter 
was, to a very great extent, insufficient for this purpose). In 
consistence it was soft and pulpy, but not more so than 
might have been expected at the stage of its development. 
Having made a longitudinal section through the whole 
length of the specimen, thereby exposing the interior both of 
the original and the intervening new substance, I found 
that throughout the whole of this section the reparative 
process w r as, as far as I could judge, going on satisfactorily. 
The slight stain and redness, observable on the outside of 
the tendons opposite to their cut ends, also existed upon the 
cut ends of their fasciculi, but w ? ere more marked upon those of 
the upper than the lower; which is easily accounted for. 
I have not examined any part of the new portion, otherwise 
than by the unaided eye, but as far as this investigation went, 
the process of its being converted into structure identical 
with the original (but differently arranged) w 7 as fast advancing. 
So much for the short, and by no means minute, examina¬ 
tion of the specimen sent to me by Mr. Bray; and supposing 
the new structures not to have been removed from their 
original situation, it would, without great contraction, have
