 Eggs are shaken until the yolks and whites are thor- 

 oughly mixed. They are then boiled hard. The shell is 

 now removed, the egg cut into suitable pieces, put into 

 test tubes and treated exactly like potato cylinders. This 

 media is said to give very characteristic growths with 

 many bacteria.

Author obtains clear agar by filtering it through a thin 

 layer of absorbent cotton, placed funnel-form in the hot 

 water filter, wet with hot distilled water and pressed in 

 place with the fingers. The bouillon must be clear to 

 start with. The flgar powder is then added and cooked 

 i hour in streaming steam.

Author states that 0.002 per cent peptone serves no 

 longer as a nutrient for bacteria, but o.oio per cent does. 

 In mineral solutions, monopotassium phosphate, mag- 

 nesium sulphate, and calcium nitrate, a dilution to o.ooi 

 per cent still nourishes algae, but not bacteria ; with 0.005 

 per cent solutions, bacteria appeared.

Author heats his filtered bouillon, to which agar has 

 been added, for i hour on a sand bath, after which it 

 filters readily if the sand temperature has been above 110 

 C. It will not filter satisfactorily if lower temperatures 

 are used.
