B. coli proved quite sensitive to dry air. The writer of 

 this abstract has found great differences among bacteria 

 e. g. B. tracheiphilus was killed by a few minutes' expos- 

 ure on cover-glasses, while Bact. hyacinth! lived under 

 similar conditions for more than a month. Jones fuund 

 his Bacillus carotovorus to be even more sensitive than 

 B. tracheiphilus. See following citations.

The per cent of malic acid in many fruits is given. This 

 varies from o.n, (certain pears) to 2.65 (red currants^. In 

 the feebly acid fruits, the cholera bacilli were dead inside 

 of 3 to 7 days ; in the the tarter fruits they retained their 

 vitality only for a period measured by hours. Usually 

 they were dead in from i to 6 hours.

 grew feebly in the presence of % per cent alum. Six 

 grew abundantly in gelatin acidified \vith citric acid.so

 In fish glue containing 0.15 per cent acetic acid, several 

 grew, but only feebly. Six grew in fish glue containing 

 0.075 per cent hydrochloric acid. The anthrax organism 

 grew better with 0.2 per cent alum than on a neutral 

 substratum.
