Products from a number of different manufacturers were ex- 

 amined, and these varied greatly in results, in part because of 

 the different methods of treatment and in part, no doubt, be- 

 cause of differences in sanitary conditions of plant and methods 

 of handling. The chart here shown may serve to show the gen- 

 eral character of the numerical results obtained.

The foregoing table serves to show the variations found in the 

 total numbers of organisms occurring on dehydrated products. 

 Study of the types predominating has given no evidence of 

 objectionable organisms, practically all the species found having 

 their habitat in soil or water. The following species were identi- 

 fied: B. vaculatus, B. denitrificans, B. Lustigi, B. cuticularis, B. 

 weichselbanini, Ps. cohaerea, Ps. sinuosa, B. subflavus, B. tena- 

 catis, B. ginglymus, Bad. mycoides, M. radiatus, Ps. viridescens, 

 Ps. ambigua.
