of FratMikel wliiic not yet provon the sole can«e of pneu- 

 monia is consiciered by many authorities to bear a casual 

 relation to the disease. Going- on to the blood examina- 

 ations, hert' the condition, number and I'elation of the 

 re(l and white blood C()rpuscdes are the only means by 

 wliicli we can distinguish between chloi'isis and anaemia, 

 ami ana'inia and leukaemia. Wliile Laveran's experi- 

 ments in 1880, demonstrating the presence in the blood of 

 the plaamodia malaria', have been corroborated by other 

 investiw'ators in his own country and by many in this, 

 hctlmsmade malaria a definite disease. The Doctor 

 proce(Mls to s[)eak of the revolution of opinions in regard 

 to the causative factor in typhoid fever. Babes and 

 Rrieo-(ii' are quoted as expressing doubt as to the Ebertli 

 l)acilliis being the sole and only cause. Babes fails to 

 find it in every case, while Brieger claims a mixed infec- 

 tion. Vanghan, of this country, in 1890, made experi- 

 ments and demonstrated the presence in drinking water 

 obtained from the source of the water supply of a town 

 suffering from a severe epidemic of typhoid fever, of a 

 number of germs capable of producing in rats and guinea 

 pigs the chairicteristic symptoms of typhoid fever, and 

 invariably fatal. Some of these germs found in the spleen 

 after death, i-esj)ond to the tests for the Eberth bacillus. 

 Vanghan concludes from this that there are found incert- 

 aiii wat(Ms a number' of germs capable of pi'oducing typli- 

 (dd fevei-, and tliat the Eberth bacillus is an involution 

 form of any one (d' these. In conclusion the Doctor 

 urges tlie profes.-^i.m in the report of all cases to add the 

 residts of micidscojiical and (diemical analysis of the ex- 

 cretions and secretions indicated. — Charlotte Medical
