27G Report of the Health of Armnals of the Farm. 



'drd. Improvement maintained. Animal's appetite returning.. 

 Blood less loaded with leucocytes. 



Dec. 2nd. — Inoculated a guinea-pig with blood of the goat, 

 which previously to being used was subjected to a moist-heat of' 

 212° Fahr. 



3rd and Afh. — No apparent effect. 



5^^. — Animal died suddenly sixtij-eight hours after inoculation. 

 The blood was examined immediately after death, and found to 

 contain bacterides in enormous quantities. 



As a counter-experiment another guinea-pig was inoculated 

 at the same time with some of the blood of the goat, which had 

 been rendered solid by exposure to dry-heat. No effects followed. 



Dec. Sjrl. — A third guinea-pig was inoculated with blood of the 

 goat in its ordinary condition — one puncture. The animal died 

 about thirty liours after inoculation. In this case bacterides 

 were present in large numbers in the blood. 



To these experiments I add two others which were had 

 recourse to for the purpose of ascertaining the length of time 

 diseased blood would retain its malignant properties. 



Dec. oOth. — A guinea-pig was inoculated — one puncture — with 

 the blood of the rabbit, which died Nov. 27th, and from which 

 the goat had been inoculated. During the interval the blood 

 had been kept in a phial, the mouth of which was closed with 

 cotton-wool. It was examined previously to being used, and no 

 bacteria were detected. 



No constitutional symptoms followed, but the site of the 

 inoculation became inflamed in the course of a few days, and 

 ultimately a small slough separated from the part. 



Jan. 2nd, 1874. — A second guinea-pig was inoculated with 

 some of the same blood. In this case tivo punctures were made, 

 as had been the practice in the greater number of the experi- 

 ments, but no effects excepting local were produced. 



The local effects corresponded with those observed in the 

 guinea-pig inoculated Dec. 30th, and terminated as in that 

 instance with the detachment of sloughs. 



Further experiments are in contemplation. At present no 

 conclusions beyond those of the deadly nature and the easy trans- 

 missibility of blood-diseases from animal to animal, of different 

 species, can be safely arrived at.
