alternately, it disappeared on November 2id, but returned on several occasion! 

 aft. T varying intervals, vis., 4th to 22nd December and 18th to 29th January 

 l'J04. On the morning of the 2Uth July the Vaginal m. m. presented a bright 

 r-d line and this condition persisted until tho'lGth August 1903, when it 

 imnnu'd its normal colour. During a considerable portion of the period that 

 this animal vas under observation there was an absence of vaginal secretion, 

 even to tho mucus usually present in small quantity, except when the mare 

 was placed in a loose box in the same building, but at a distance from the 

 stallion. 



Petechiffi dark red in colour were recognized on he 20th November 

 invading the in. in. of tlio vaginjfr circular in form and 7 l th to 3 1 , J th inch in dia- 

 meter. In blood collected from several of these small extravasations for micro- 

 scopical examination, the trypanosoma was demonstrated. After a period of 24 

 hours had elapsed little, if any, signs of the remaining petechioo could be dis- 

 covered. It was not until 23rd December 1903 that the trypanosoma wag 

 found in the vaginal mucus for the first time, although a large number of 

 observations with that end in view had been conducted during the previous 

 course of the case. 



The temperature of the animal, during the period of ten months which 

 elapsed between tho 3rd June 1903 and 31st January 1904 followed for the 

 most part an almost even course, the morning and evening records showing but 

 a few points variation above or below 37 and 38C. respectively. The 

 maximum evening reading 39*6 C. was noted on one occasion at the time of 

 the eruption of No. 21 plaque, the minimum morning 36'9 C. being also 

 registered but once.
