THE BEGINNINGS OF LIIE. 



from deposit until the twelfth day, M^hen it was examined 

 microscopically. No organisms of any kind could be de- 

 tected. 



No. XLIII. Hay Infusion +

part of Carbolic 



Acid, showed no apparent change^ for the first five days, 

 though, on the sixth day, a slight deposit was noticed at the 

 bottom of the flask. The deposit had increased, and was well 

 marked by the twelfth day, when, on microscopical examina- 

 tion, there were found, amongst the granular flakes of the 

 deposit, Torulce of several varieties of size and shape. Many 

 were spherical, others ovoid, or having an elongated oat-like 

 shape ; some were of the ordinary colour, and others were 

 brownish in tint. The variety was most striking. No Bac- 

 teria were seen, though there were multitudes of active parti- 

 cles which seemed to diff'er from the minute spherules of 

 undissolved carbohc acid. 



Fluids (in vacuo) boiled for five minutes^ and Flasks Sealed 



dtcring Ebullition. 



No. XLIV. Turnip Infusion, in seventy-two hours, 

 showed a slight turbidity, which gradually increased. On the 

 eighth day there was a considerable quantity of flake-like 

 sediment, and some amount of general turbidity. On the 



r 



thirteenth day the vacuum was found to be still partly pre- 

 served. When the flask was opened the fluid was perceived 

 to have a foetid odour, and an acid re-action; and, on micro- 

 scopical examination, multitudes of Bacteria and Vibripnes 

 were seen. In the flake-hke aggregations (made up almost 

 wholly of these organisms) there were also a number of 

 large thick-walled spores ; some already formed, and others 

 in process of formation. 



^ The alteration in colour was less marked than in the similar mix- 

 ture which had not been boiled, though the turbidity was just as 

 obvious.
