third of the tube was occupied by the fluid^ and the 

 remaining two-thirds contained ordinary air. It was 

 exposed for thirty minutes to a temperature of 2I2''F^ 

 and for forty minutes to %^^Y {i^d'Q)^ in a bath 

 saturated with carbonate of potash. Fifty-nine hours 

 after having taken the tube from the bath (during which 

 time it had been maintained at a temperature of about 

 75°F)j it was divided by a file, and the fluid was sub- 

 mitted to a microscopical examination. In the fluid. 

 Prof. Mantegazza says he found living specimens of 



'Bacterium termo. 



In 1862, Prof. JefFries Wyman, of Cambridge^ U.S., 



performed, and subsequently recorded the following 



experiments^. ^Exp. xxxiv. (3.) March 27th. Juice 



of mutton, in a hermetically sealed ftask, was boiled 



five minutes in a Papin's digester, under a pressure of 



two atmospheres [i20-5°F]. A film formed on the 



fourth day. It was opened several days later in the 



presence of Prof. Gray, and found to contain Vibrios 



and Bacteriums, some of them moving with great 

 rapidity.' 



The next experiment was also made with the same 

 itional 511^^ y ( kind of solution 2, It is thus recorded :—^ Exp. xxxv. (3.)

 In two other experiments, in which beef juice was employed instead 

 of mutton juice, and in which the flasks were raised to the same tem- 

 peratures for fifteen minutes, no organisms were found.
