split in many ways by enzymatic action, grew good cultures both alone and 

 in combination with other materials. 



«.",! As noted in all other testa the Lipman and Brown agar grew tin- 

 best cultures and apparently developed their distinguishing chromogenic 

 characteristics much better than the sodium asparaginate agar. 



(6) From macroscopic comparisons the starch media seemed to be the 

 real competitor of the Lipman and Brown agar.

Testing Organisms from Laurel Soils. 



Plated on Lipman and Brown Agar. 



When transferred to slants of different media. 



Samples taken 7/27/1915. 



Description of colonies from which transfers were made: 



No. 1. Round, curled edge, wrinkled in structure, green in color, a mold 

 1.5 cm. in diameter. 



Xo. 2. Elliptical, curled edge, wrinkled in structure, green in color, a 

 mold 1.5 em. long. 



Xo. 3. Round, lobate edge, wrinkled structure, brown (pale) in color. 

 a mold 1 cm. in diameter. 



Xo. 4. Round, entire edge, granular structure. White raised center with 

 brown ring outside, apparently a mold about .5 cm. in diameter. 



Xo. 5. Discoid, crenate edge, smooth structure, milk white in color. 

 .5 cm. in diameter, a mold. 



Xo. G. Round, entire edge, smooth structure, salmon red in color. 3 mm. 

 in diameter. 



Xo. 7. Round, ciliate edge, granular structure. Yellow in color, deep 

 yellow at center, about 1 cm. in diameter. 



Xo. 8. Round, ciliate edge, granular center and fibrant outer portion 

 describes structure. Center dark green, border light green, about 4 mm. in 

 diameter. 



Xo. 9. Round, plain edge, smooth in structure, salmon red with yellow ish 

 outside ring, produces yellow pigment soluble in media, about 4 mm. in 

 diameter. 



Xo. 10. Round though dented, crenate edge, spotted structure, white 

 in color, about 8 mm. in diameter.
