Dr. Dolley called attention to the many ways in whicli bio- 

 logical science is being applied in industrial and commercial 

 ■processes, and referred to the methods employed in the preser- 

 vation of food-stuffs, as milk, fruit juices, etc. He spoke of 

 experiments which he had been making since July on the 

 bactericidal effects of carbonic acid gas. This gas proved 

 sufficient to check all fermentative processes in many cases 

 where the fluids were first exhausted of air and then subjected 

 to the action of CO2 under "high pressures.
