 Injection of these organisms into calves gave a negative result. 



In the pneumonia of lambs the author found six different kinds of 

 microbes. (1) Large cocci and diplococci • 5 yu, in diameter ; (2) medium 

 sized cocci and diplococci • 2 /^ in diameter ; (3) small cocci, diplo- 

 cocci, and streptococci • 1 /x in diameter ; (4) rodlets • 5-1 • /u, long 

 and 0-3 fjL broad ; (5) small bacilli • 5 /x long and • 1 /x thick ; 

 (6) streptobacteria 0*2 /x long and 0"1 /x thick. Grown in bouillon, on 

 gelatin, and on potato, these developed white colonies of single cocci, 

 yellowish-white colonies of short rods, and, on potato, brownish-red 

 colonies of larger bacilli. Most of these were probably the result of 

 secondary invasion.
