734 EXPERIMENTS ON "CATTANACH DISINFECTANT AND DEODORANT," 



not belong to putrefactive organisms ; the gelatine did not become 

 liquefied, nor was there any putrefactive smell. On the other hand 

 in all control-tests the gelatine became rapidly liquefied under 

 stink. 



In order to obtain some information as to whether the " Cat- 

 tanach " possesses deodorizing properties, I employed a putrefying 

 mixture, emitting a disgusting stink ; it had been prepared in the 

 same way as above (10 parts of water, 1 part of minced fish). 

 Samples of this mixture in portions of 150 gr. each were distributed 

 in suitable glass-flasks, the two powders added in the proportion 

 of 1:150, 1:50, 1:25, 1:10, and thoroughly mixed with the con- 

 tents of these flasks. The result was this — the " Cattanach 

 powder " was superior in its action to the " Carbolic powder." 

 In the flasks containing the " Cattanach " in the proportion 

 1:10 and 1:25 the really sickening stench had disappeared 

 entirely (first case), or nearly so (second case) after about four 

 hours, whereas in the proportion of 1:50 this state was attained 

 not until after about a day. The condition of the flasks was still 

 the same after 25 days. However, in the flask containing the 

 Cattanach in the proportion of 1:150 the stench did not disappear, 

 although it was less strong than that emitted from the control-flask. 

 On the other hand a thorough deodorization of the samples treated 

 with " Carbolic powder " had not taken place in either of them 

 after three days, although the stench had considerably diminished, 

 we may say, pretty nearly ceased in the flask with " Carbolic 

 powder" in the proportion of 1:10. After seven days the 

 deodorization was complete, and so it remained. The sample 

 containing the powder 1:25 was not quite deodorized after seven 

 days ; on examination after 25 days it was found free from any 

 ofiensive smell, and so was the sample with the "Carbolic powder" 

 in the proportion of 1:50. (After this period the control-flask still 

 emitted a bad smell). Lastly, there was not much difierence
