82 BACTERIOLOGY 



Great care and ingenuity are necessary to arrive at correct con- 

 clusions, particularly in the case of animal tendons. In many 

 instances quite stable compounds are formed between tendon 

 and germicide, and living organisms may be so imbedded in such 

 a substance that subsequent growth in a test-culture is impossible, 

 "the use of a suitable inhibitor, and, prior to final culture- tests, 

 a prolonged soaking in sterile water, will promote the accuracy 

 of the results.
