A Report on the Microscopic Objects found in Cholera Evacuations. 



By Dr. T. R. Lewis. 1870.

 existence of a specific germ as its cause — Object of the report to test these views. — I. The fungoid 

 theory, and the microscopic objects found in choleraic evacuations — Section I : Two classes of 

 cysts seen — Observations of Quekett, Swayne, Brittan, Budd, Burk, Berkeley, Robin and Hallier —

 tions — Observations on boiled solutions of meat — Development of paramecia — Organisms seen in 

 fresh cholera dejections. — II. Pettenkofer's theory as to the soil in relation to cholera — The theory

 Agent or Agents Producing Cholera. By Drs. Lewis and Cunningham. 1872. 



Inteoductory. — I. Microscopic Examinations op Human Blood. 



A. The blood in cholera cases. — Methods adopted for its continuous examination — (1) Blood 

 when treated with osmic acid and acetate of potash — (2) Appearance of blood when enclosed in 

 " wax-cells " — Changes in the masses of bioplast — Principal points of interest in the observations 

 — Persistence of amoeboid bodies in cholera blood.
