FORM No. 14. 



Obtained from the air in the veterinary hospital. 



Marpholoffy. A diplococcus i" in diameter. 



Biological Characters. A non-liquefying aerobic, probably motile diplococcus. 

 In Bouillon it produces turbidity and a light greenish sediment forms in bottom of 

 tube. A white scum forms on tube at surface of liquid. On potato it forms a 

 greenish yellow growth along the streak. The growth on potato is not luxuriant 

 and has a granular appearance. The form does not grow very luxuriant at a 

 temperature of 102° F. In Gelatine Stick culture it forms a dish shape white 

 growth and does not liquefy the gelatine. On Agar Streak a greenish yellow, 

 slick growth with a smooth outline appears. On Agar Plate it forms yellowish 

 green colonies with a ragged outline. The colonies present a granular appearance 

 with a light or transparent ring about half way between the edge and the center. 

 The colonies that grew on the surface are larger than those that grew on the bot- 

 tom of plate. On Lactose Litmus Agar it forms large white colonies which do 

 not produce lactic acid. (See plate.) 



FORM No. 15. 

 Red yeast. 



Obtained from the air in Professor Troop's barn. 



Morphology. It appears as oval shaped cells 3 to 4° long and 2" broad. 



Biological Characters. Aerobic. In Bouillon it forms a reddish sediment in 

 "bottom of tube. On Potato it produces a pinkish though not luxuriant growth. 

 On Ager Streak it forms a pinkish slick growth. It does not grow at the tem- 

 perature of 102° F. In Gelatine Stick culture it grows only on surface and does 

 not liquefy the gelatine. (See plate.) 



FORM No. 16. 



Obtained from the air in Professor Troop's barn. Only one colony was 

 obtained. 



Morphology. It appears as tetrads, and is composed of four germs in a group ; 

 it is about 2^"^ across. 



Biological Characters. A non-liquefying, facultative anaerobic motile, non-spore 

 forming tetrade. In Bouillon it produces turbidity and forms a white sediment in 

 bottom of tube. On Agar Streak it forms a white branched growth. On Potato 

 the growth is slow, does not show the branched appearance, and has a granular 

 iippearance. In Gelatine Stick culture it forms an irregular dish shape growth.
