which still enshrouds those diseases ordinarily known as blood- 

 diseases, was brought to their notice. Since then the following 

 additional experiments have been carried out with reference to 

 the malady known as 



" Splenic Apoplexy." 



January 24zth, 1 P.M. Inoculated a guinea-pig (No. 1.) One 

 needle puncture on the inner part of each thigh. Needle soiled 

 with some blood which was found effused beneath the lining 

 membrane of the heart of an ox which had died from an attack 

 of splenic apoplexy. The blood was examined microscopically, 

 and found to contain bacteridies in immense quantities. 



On the morning of the 27th, about 65 hours after the inocu- 

 lation, the guinea-pig was found dead. No indications of 

 ill-health had been previously observed. Its blood contained 

 bacteridies in abundance. 



27th, 9.30. A.M. Inoculated a guinea-pig (No. 2) with blood 

 of guinea-pig (No. 1). Two needle punctures. Animal found 

 dead 46 hours after inoculation. Bacteridies in blood. 



February Srd. Inoculated a rabbit with blood of guinea-pig 

 (No. 2). Rabbit died very suddenly on the following day, 

 about 13 hours after the inoculation. No indications of illness 

 were in this case recognised prior to death. 



Ath. Inoculated a second rabbit with blood of guinea-pig 

 (No. 2), diluted with eight parts of water. Negative result. 



Same day inoculated a small terrier dog with blood of rabbit 

 (No. 1). Two punctures. 



bth. Animal dispirited. Shows much pain and stiffness of the 

 inoculated limbs. 



6^/i. Local suffering increased. Animal refuses food and is 

 very restless. The indications of illness increased during the day. 

 By night the restlessness had, however, passed off, and the 

 animal now maintained a recumbent position, and could scarcely 

 be made to move. 



1th. Early this morning the animal was found to be sinking. 

 Died at 8.30, about sixty-four hours after the inoculation. The 

 blood was very carefully examined, but no bacteria nor bacteridies 

 were detected. All the structures of the body were free from 

 organic lesions. 



S)th. Inoculated guinea-pig (No. 3), with blood of dog. Two 

 punctures. Ncyative result. 



Same day inoculated guinea-pig (No. 4) with blood of guinea- 

 ,pig No. 2, which died January 2yth. Blood eleven days old. 

 Guinea-pig died within forty-two hours of the inoculation. 



\A.t]i. Inoculated guinea-pig (No. 5) with blood of guinea-
