results in the hands of several breeders warrant an ex- 

 tended use of the capsule for this purpose. The capsule 

 method is as follows: Procure a gelatin capsule (Plan- 

 ten's are good) one-half or one ounce capacity, then have 

 the mare served by the stallion, immediately afterwards 

 insert the capsule (with the cap removed) into the vagina, 

 dip up with it the semen ; the capsule containing the 

 semen (fertilizing element of the male) is then carried 

 forwards and passed through the neck (os) into the womb, 

 where it is left; this method is likely to be very useful in 

 those mares that eject the semen after a service. The 

 condition of the lining membrane has been mentioned 

 among the causes, impregnation is not likely to occur if 

 there is any discharge from the vagina, the injection of 

 a solution of boric acid, permanganate of potash or bak- 

 ing soda one ounce in three pints of clean water two 

 hours before mating may overcome the acidity, which is 

 immediately fatal to the spermatozoa. Chronic bulling 

 in cows is best treated by spaying and fattening for mar- 

 ket. Sterility (barrenness) in sheep or rather a small 

 lamb crop may be due in addition to the causes already 

 mentioned as aifecting either sex, to the ewes being left 

 undocked or untagged, thus preventing the proper per- 

 formance of the act of breeding; the latter operation 

 (tagging) should be performed every year just at the 

 beginning of the breeding season.
