Note 115 — Chapter VI
Reading edition
This is not invariably the case: other samples of puer examined have given off NH3 when similarly treated, but only in small quantity. A similar instance has been observed by Rideal and Orchard in the liquefaction and decomposition of gelatin by B. fluorescens liquefaciens (The Analyst, October 1897), where the quantity of ammonia produced was insignificant, amounting even after 16 days’ incubation to only 0·168 grm. of N per 100 c.c., corresponding to 0·204 grm. of ammonia.
