THE DISEASES OF CATTLE. 307 



are discharged into the uterus, through the fallopian tubes, and 

 the same is vitalized by the male semen in the act of copula- 

 tion. So it will be perceived that the uterus has two inlets, 

 coming from the ovaries, and one outlet, which is the lips of 

 the vagina. 



The arteries which supply the uterine organs with blood, are 

 named vaginal, uterine, and spermatic. The vaginal is derived 

 from the internal iliac ; the uterine, from the external iliac ; 

 and the spermatic comes directly from the great aorta. 



This brief description of the form, function, and location 

 of the uterine organs, may possibly .prove of some value to the 

 husbandmen of this country, who are not expected to be posted 

 on the subject, and cannot spare the time to familiarize them- 

 selves with the technicalities of the schools, yet have intel- 

 ligence enough to comprehend plain matters of fact. 



On the Selection of Animals for Spaying. — If the animal 

 be intended for milking purposes, a good milker must be se- 

 lected, for the operation will not transform a poor milker into 

 a good one. She must necessarily be in possession of those 

 constitutional peculiarities which have been observed to prevail 

 in animals renowned as first-class milkers. The operation will, 

 without doubt, improve the quality of the milk, yet may not, 

 under all circumstances, increase the quantity, although the 

 French dairymen contend that " the cow will be found to give 

 as much milk after eighteen months as immediately after the 

 operation; and there was found, in quantity, in favor of the 

 spayed cows, a great difference." About three years ago, I 

 spayed a cow, the property of a gentleman residing in South- 

 borb. She continued during this period to yield her usual 

 quantity of milk, yet gradually accumulated fat, so that she 

 was known in the neighborhood as the "/a< cow" When in 

 this condition, the daily yield of milk gradually decreased, 

 and the owner at last sold her to the butcher. I learned from 

 parties who bought the meat, that it was of superior quality 

 even to that of an ox or steer, and commanded a higher price. 

 Among other animals that I have spayed, several have run to 

 fat, as the saying is, and at the end of from eighteen months
