Spayed cows apparently make better mothers than the entire 
animals, taking kindly to calves of other cows placed with them. 
The conclusions reached after carefully studying the results 
of my own experiments and the observations of others as re¬ 
corded in the veterinary literature of the United States and 
Europe, are as follows : 
Cows which have come to the age of decline and are not 
profitable as breeding animals, if spayed can be made profitable 
from the milk produced while fitting them for the slaughter. 
The operation is also indicated in the nymphomaniac cow. 
Careful tests, however, indicate that the value of this operation 
in dairy cows has often been exaggerated. 
HEALING OF EXTERNAL WOUNDS. 
By J. A. Sloan, V. S., St. Joseph, Mo. 
Read before Missouri Valley Veterinary Medical Association, June 25, 1900. 
The particular phase of the subject to be discussed in this 
paper is that relating to the pathological processes in the heal¬ 
ing of wounds and with no particular reference to their treat¬ 
ment. The discussion will also be principally confined to 
wounds of such a size and condition as are healed by the visible 
formation of new tissue and less fully to those which heal 
by primary union. There are two reasons why this part of 
hypertrophy and regeneration of tissue is selected. 
1. Because such wounds are of everyday occurrence and 
therefore important. 
2 . Because the subject is too vast to discuss in its entirety. 
It is said that “a wound is a recent solution of continuity 
of the living tissues induced by some mechanical caused’ 
Some writers hold that all wounds are on the outside surface of 
the body, involving an abrasion of the skin, but this will hardly 
cover contused wounds. While external influence may hasten 
or retard the process of repair they will not be considered 
except when suppuration intervenes.
