 The appearance of the bacteria siilijeLted to the anti- 

 septics, as shown on the jilate, strongly suggests the aji- 

 pearance of or.ganisms in old cultures, viz,: involntuui 

 forms, and the two phenomena ma\' be due to the same 

 cause, the i]]^'(Jlution Tonns arising from tin hannful ac- 

 tion of products excreted by the liacteria, 01 arising from 

 the action of substances de\ehjped in the media as the 

 result of liactenal occupation

 of 2 per cent phenol a still more effective mixture is

 cifect of the 1 per cent snVilimate solution on some or- 

 ganisms, but increased it on others,
