between the condition of the flask with Carbolic powder, 1:150, 

 and that of the control-flask, after 25 days ; in this respect the 

 matter was about the same as with the corresponding Cattanach 

 experiment. 



In putting together the res\ilts of the above experiments, we 

 may say that the " Cattanach Disinfectant and Deodorant" falls 

 short of being a germicide for the bacillus of typhoid fever, and 

 therefore cannot be employed in the disinfection of typhoid dejecta; 

 it acts antiseptically, at least to a certain extent, as is shown 

 above ; and, lastly, it is a quick deodorizer, but not in so small 

 proportions as are stated in the directions regarding its use. From 

 what I have been able to see, the composition of the preparation 

 (to judge from colour, smell, and general appearance) is not 

 constant, and failing in this way there cannot be any guarantee 

 for its having constant properties. Besides, some objection might 

 be taken, in my opinion, to the price of the powder, which by far 

 exceeds that of other preparations for the same purpose.
