ON THE OPERATION OF TENOTOMY IN THE 
HORSE. 
By Gr. W. Yarn ell, 
Assistant-Professor, Royal Veterinary College. 
(Continued from p. 559.) 
Having considered the comparative merits of the two 
modes of operating for division of tendon or ligament, we 
will next endeavour, very briefly, to explain the way in which 
these organs are repaired. 
The first result of the division of a tendon or ligament, 
however neatly it may have been effected, is the loss of a 
small quantity of blood, which becomes effused between the 
divided ends of the tendon or ligament, and also into the sur¬ 
rounding areolar tissue. For some little time, also, after 
actual haemorrhage has ceased, exudation of blood, minus the 
red particles, continues to take place. This may even last 
for a day or two. The material so poured out infiltrates the 
fibres of the divided organ, -and also the surrounding tissue 
which forms a sheath for the tendon, thereby slightly in¬ 
creasing the size of the limb at this part, and at the same 
time forming a temporary bond of union. The effused mass 
also prevents, to a certain extent, the areolar tissue collapsing 
into the gap caused by the receding of the two ends of the 
severed tendon or ligament; but it is not thought to take 
any share, or at any rate but very little, in the formation 
of permanent tissue. 
This effused mass very soon becomes organized in the form 
of lymph-cells, and these, it is said, speedily become more 
distinctly nucleated and elongated in the shape of spindles;
