ticularly one like Sarcina Lutea. The second plate averaged 3,570 colonies per cubic 

 centimetre. In general characters they were the same as in the first plate. 



August 4, 1902. Water in aquarium. Agar plates awaged 3,570 colonies per 

 cubic centimetre. These were in all respects like those of July 31. 



Same water in sunlight since July 31. )Agar (plates average 4200 oolo^nies per 

 cubic centimetre. These colonies contain the same bacteria as in the aquarium water, 

 but in fewer numbers. Further, there is present a fluorescent bacillus, making up half 

 the number of colonies present. 



• August 8, 1902. Water in aquarium. Agar plates develop 7,870 colonies per cubic 

 centimetre. These colonies are of the same type as those found on previous plates with 

 the addition of about 1,000 colonies of B. Mesentericus Vulgatus per cubic centimetre. 



Water in sunlight. Agar plates develop 37,070 colonies per cubic centimetre. 

 These consist mainly of B. Fluorescens Liquescens; also of Sarcina Lutea, and an 

 occasional colony of B. Subtilis.
