Consequently the sheep in the shed^ though they consumed 

 nearly one-fifth less food^ made above one-third greater progress. 

 The circumstances of the experiment were^ if anything, unfavour- 

 able to the sheep in the shed : the turnips^ by being stored in a 

 house for their use^ became drier than those consumed by the

 was given after every shower of rain. 



XVIII. — The Detection of Pregnancy in the Mare and the Cow, 

 By William Youatt^ Esq. 



Among healthy animals,, the impregnation of the female rarely 

 fails to be the result of an intercourse between the sexes. The 

 assurance^ however^ of this having taken place is, occasionally^ an 

 affair of considerable interest^ and of no little difficulty ; and the 

 value and the destiny of the female may very much depend on the 

 decision of the question. A certain time having elapsed the thing 

 will speak for itself; but are there any symptoms or circum- 

 stances that will warrant the veterinary surgeon, or the agricul- 

 turist^ in giving a decided opinion on the case in an early period 

 of supposed pregnancy ? 



It occasionally happens that the fifth or the sixth month arrives, 

 and, even to the practised eye, there are few or no indications of 

 conception having taken place. There are, also, but somewhat 

 unfrequently, diseases which very closely simulate this natural pro- 

 cess. Can the veterinary surgeon or the breeder decide ? The 

 answer is in the affirmative, and plainly and unequivocally. This 

 is one of the boons which the veterinary art can now confer on the
