On Agar Plate it forms small white irregular colonies which are fringed at the 

 edge. The growth at a temperature of 102° F. is white, smooth, very luxuriant, 

 and grows over whole surface of Agar. On Lactose Litmus Agar Plate the col- 

 onies are white and produce a slight change in the litmus, showing the produc- 

 tion of a small amount of lactic acid. 



FORM No. 7. 



Obtained from the veterinary hospital. 



Morphology. A sarcena about li" across. 



Biological Characters. A non-liquefying aerobic sarcena. It grows in most 

 media at room temperature. In Bouillon it produces turbidity and forms a white 

 sediment in bottom of tube. On Gelatine Stick cultures a very slight yellow 

 growth forms on the surface. On Agar Streak it gives a slick yellowish growth. 

 The growth extends over surface of Agar, and has an irregular outline.* On 

 Potato it forms a deep yellow, slick growth along the streak. The growth at the 

 temperature of 102" F. was very slight, and has an irregular outline. On Agar 

 Plate it forms small, yellow granular colonies with a smooth outline. The col- 

 onies that grow on the bottom of the plate are transparent at the edges and gran- 

 ular in the center. On Lactose Litmus Agar Plate small white colonies are 

 formed, which produce a slight change in the litmus showing the formation of 

 lactic acid. 



FORM No, 8. 



Obtained from the veterinary hospital. Only a single species was obtained. 



Morphology. A short round bacillus 2" long and 1" broad. It occurs singly. 



Biological Characters. A non-liquefying, non-spore forming motile bacillus. 

 The growth on usual media at the room temperature is very slight. In Bouillon 

 it produces slight turbidity and forms a brownish sediment in bottom of tube. It 

 does not grow on potato. In Gelatine Stick it produces a very slight, transparent 

 growth. The growth at a temperature of 102° F. is very slight, and is of a pale 

 white color, with an irregular outline. On Agar Plate it forms small, white or 

 transparent colonies with a smooth edge. Lactose Litmus Agar Plate, it produces 

 no change in litmus, showing the production of no lactic acid. In a hydrogen 

 atmosphere this form grows very luxuriant. The growth is white granular and 

 extends over surface of Agar.
