The behavior toward rennet was not abnormal in any ca.se. In 

 the casein test coagulation occurred in i i-i 3 J^ minutes. The 

 behavior in the incubator was also parallel to that observed in 

 any good, fresh milk. The rising of cream showed nothing ex- 

 traordinary in the milk from either cow. The measurement of 

 the fat globules in the milk of cow No. Ill, showed a diameter 

 of 0.00135 to 0.0193 mm., while that of Cow No. I, gave a meas- 

 urement of o.oorig to 0.0149 mm. 



If we now compare the data under tables A and B with each 

 other we first observe a higher specific gravity in table A and a 

 larger amount of .solids than in table B. It is thereby indicated 

 that the milk of nymphomaniac cows is not only somewhat richer 

 in its contents than that of normal, but also of castrated milk 

 animals. In castrated cows, it approaches more nearly the char- 

 acter of normal milk. 



In conclusion, it should not be forgotten that a thorough clin- 

 ical examination and a rational handling of diseases of the genital 

 apparatus of cows, in spite of the many disagreeable features con- 

 nected therewith, belong nevertheless among the most important, 

 prominent and appreciable duties of veterinary practice, and not 

 alone contribute to the increase of the national resources and 

 dissipate errors and discontent in agricultural industries, but 

 also add to our knowledge of the cause of sterility, and, not the 

 least, add to the well deserved standing of veterinary science. 

 In reply to the question as to how we might increase veterinary 

 authority and efficiency in this regard, we would unqualifiedly 

 answer that, in order to reach this plane with security, a great
