INTERMITTENT FEVER. 325 



is so subject; especially in view of the fact, that 

 infection did not occur in the natural way, that the 

 rabbit is very subject to various forms of septi- 

 caemia, and that prior to these experiments no eVi- 

 dence had ever been presented to show that the 

 rabbit experiences any harm from respiring an 

 atmosphere charged with malaria. 



Professor Ceri, however, claims to have produced 

 in rabbits intense febrile paroxysms of a decidedly 

 intermittent type, and continuing for a long period, by 

 the hypodermic injection of artificially cultured 

 malarial soil exposed for ten days to a temperature 

 of 35 to 40 C. 



This is a very definite statement, and, if sup- 

 ported by temperature-charts showing the fact, 

 would have great weight. 



In a recent report (March 18, 1883) to the 

 Italian Minister of Agriculture, Tommasi-Crudeli 

 refers to the production of intermittent (?) fevers 

 in the lower animals by the subcutaneous injection 

 of the blood of malarial-fever patients, and states 

 that he made extensive preparations to continue 

 his experiments in this direction during the year 

 1882 ; but he was unable to carry out his inten- 

 tion for the reason that not a single case of perni- 

 cious fever was received during that period into 

 the Roman hospitals. 1 



Here, then, we have a confession which makes it 

 evident that the pernicious fever, ascribed to malaria,
