XIV APPENDIX. 



more or legs stationary for some 8 months, but after the animal had been used 

 for the purpose of covering, symptoms increased in severity. 



The oedema of the sheath augmented and decreased from time to time 

 during a period of months ; at first the swelling was found to be hot and tender 

 on manipulation, but later these symptoms were absent. At one time the swell- 

 ing and cedema of the parts would be uniform and bilateral, while on another 

 occasion after reduction and absorption of the osdema and subsequent period of 

 rest, it would be followed by a unilateral swelling of the sheath, which once 

 persisted for a period of 12 days and then diminished in size. 



One other symptom which has to be noted occurred on the 3rd December 

 1903, viz., swelling of the left hock accompanied by effusion -of fluid into the 

 joint. This condition was maintained for some days but finally disappeared on 

 the 22nd December. 



During a period of 800 days, the temperature, pulse, and respiration of this 

 animal have been taken morning and evening, and only on very few occasions 

 have the readings been anything in excess of the normal limits of 37'2 to 

 38*3 0. On such occasions only a slight exacerbation of the temperature 

 would be recorded on the previous evening with a normal temperature on the 

 following morning. The evening before the appearance of a plaque, a rise of 

 a .degree has been registered on three occasions, and one morning when a fresh 

 plaque in addition to considerable oedema on the under-surface of the abdomen 

 had made its appearance, the temperature of the previous evening was as high 

 as 40 C. 



It is impossible to form an exact opinion as to the date on which this 

 stallion contracted the disease, as no records are forthcoming on the subject. 

 It is more than probable, however, that it must have been a date between its 

 arrival at Masauta on the 10th March, and removal to the dep&t on 7th Septem- 

 ber 1902. The swelling of the sheath and scrotum was therefore the only 

 outward and visible manifestation present during the period of eight months, 

 August to March 29th, previous to the animal's despatch to Bareilly. As the 

 first plaques made their appearance three days after the animal's arrival at the 

 latter Laboratory, it would seem likely that the railway journey, March 29th 

 to 31st, at 6 P.M., during which Yadgir was much shaken and had but little 

 rest, acted as an exciting cause in lighting up the disease. 



If we locate the first symptom noted, viz., the swelling of the. sheath, as 

 having commenced during the middle (15th) of August 1902, it will be found 

 that the first plaque only appeared 232 days later aud that 36 in all had made 

 their appearance during a period of 522 days.
