Bacterial Flora of the Semi -Desert Region of New Mexico. 239 



A,. 



Morphology — Rather large coccus. Single and pairs; oc- 

 casionally found in short chains. Stains readily. Size, 1.2 ;>-. 



Gelatin Stab. — Abundant growth, but this decreases down- 

 ward. After several days a small pit appears at the surface, 

 which increases slowly. The surface growth is orange 

 colored. 



Glucose Gelatin. — Growth doubtful. No gas. 



Gelatin Slant. — At first a slight growth, which increases 

 slowly and becomes moderately abundant. Very irregular 

 and granular. Orange color. Slight liquefaction after seven 

 to ten days. 



Agar Slant. — Growth slight but increases slowly. Quite 

 restricted, dry and granular. Orange colored. 



Bouillon. — Slight cloudiness with small flocculi present. 

 Orange colored precipitate at bottom. 



Glucose Bouillon. — Cloudiness in open arm. Precipitate. 

 No gas. 



Milk. — No change. 



Potato. — Very slight growth. Orange color. No further 

 change. 



A 5 . 



Morphology. — A medium-sized micrococcus. Sarcina, the 

 packets becoming large. Stains readily. Size, 1 />-. 



Gelatin Plate. — Surface colonies larger than deep-seated 

 ones. Bright pink and about the size of a small pin-head. 

 Under the microscope the deep colonies are irregular, strongly 

 lobed and granular. Color, pink. 



Gelatin Stab. — Abundant growth along stab, decreasing 

 downward. The slight surface growth increases with age 

 and becomes dark pink or nearly red. No liquefaction. 



Glucose Gelatifi. — Apparently no growth. No gas. 



Gelatin Slant. — Growth slight at first, but becomes quite 

 abundant at the end of a week. The outline is quite irregular 

 and the surface rough. Not shiny. No liquefaction. Color, 

 pink. 



Agar Slant. — Slight at first, but increases with age. Very 

 irregular in outline and granular. Smooth and shiny, but 

 shows granular heaped up patches in places. Pink.
