Cow No. II, Reh, Simmerthal breed, was about 12 years old 

 and weighed 610 Kg. The cow calved the last time on May 25, 



1903, and -Still gave 3.5 liters of milk per milking, in January, 



1904. The first signs of nymphomania occurred late in October, 

 1903, and the neglected disease became very .severe in January, 

 1904. 



Cow No. Ill, Graf. vSimmerthal type, 7 years old, in good gen- 

 eral condition. vShe calved last on the 23rd of February, 1903, 

 became highly nymphomaniac during the summer of 1903, and 

 was castrated on the 3rd of the following December. Early in 

 January, 1904, she weighed 800 Kg. and on January 13, yielded 

 5.5 liters of milk per milking. 



The analysis gave the following results : 



A. MILK OF NYMPHOMANIAC COWS. 



The reaction to rennet was not remarkable in any test made. 

 The milk coagulated under the casein test in 9)^ to 13 minutes. 

 The coagulation was in no test abnormal. Tests of the behavior 

 of the milk in the incubator likewise showed normal characters. 



On the other hand, the tests showed, on the whole, a defective 

 rising of cream in that, at a temperature of 10 to 12° C, no evi- 

 dent line of demarcation between cream and milk appeared. Meas- 

 ured by the micrometer, the fat globules, in the milk of cow 1, 

 showed a diameter of 0.0022 to 0.0104, and in cow II, of 0.0017 

 to 0.0104 mm.
