 speculation, and cannot stand before the results 

 of exact experiments. Let us then briefly review 

 these results, or at least those which have been 

 most recently reported, and seem most worthy of

Passing by the researches of Salisbury and other 

 claimants to the honor of having discovered the 

 malarial parasite, we come at once to the investi-

 the vicinity of Rome, and as a result of which

 Bacillus malarice. 



The evidence in favor of this discovery is stated

 tricts, in Italy, numerous shining oval and mobile spores,

 appearances ; while the bacillus was also found in the 

 blood of such animals, taken after death. The spores

 ments, into long threads, which are at first homogeneous, 

 but later divide, while new spores develop in the interior 

 of the segments. The position of the spores, which are
