found so objectionable in carbolic acid. A one per cent, 
solution of trikresol in water kills the pus-producing 1 micro¬ 
coccus aureas with certainty in half a minute, a one half per 
cent, solution does the same in ten to twelve minutes, while 
it destroys the cholera vibrio in one to two minutes. 
A one per cent, solution (a full teaspoonful, though more ! 
accurate seventy-seven minims of trikresol to one pint of 
water) is the most useful one; for many cases a one half per 
cent, solution answers; a one quarter per cent, solution is 
employed for inhalation, and to disinfect rooms, etc., and a two 
per cent, solution should be used in an atomizer. . I have no- j 
ticed frequently that the so called “ mange, a skin disease 
which is very common to dogs, attacked the latter whenever 
their kennels or whatever places they live in were damp. 
Though sulphur internally accelerates the cure, disinfectants 
locally applied always seemed to me from the very nature of 
the disease the proper treatment. Whoever has owned a St. 
Bernard dog will know that it is almost impossible to keep 
them from wet places, if such are near them. I have a 
beautiful dog of that breed of a size enormous even for such 
an animal. But when after a rain or from other causes the 
ground is damp he will leave his dry kennel and selecting the 
wettest place rest himself there. 1 hough he receives his j 
baths regularly, 1 had long feared that he would contract 
some disease from this inveterate habit of his. His hair be¬ 
gan to fall out in places and he evidently suffered from the 
mange. As a test I prepared a two per cent, solution of 
trikresol in water and poured the same for a week all over 
the large yard, especially on the places the dog seemed to 
prefer. By the aid of an atomizer the same solution was 
sprinkled all around his kennel. In four days all the places 
on the underside of his body, where a St. Bernard dog has 
but very little and smooth hair, had commenced to heal, but 
three large spots on his back remained in the same state as 
before ; the hair had fallen out and the skin looked like in a 
case of moist eczema in a human being. I now washed the 
places with a one per cent, solution of trikresol and had the 
satisfaction within twenty-four hours to obseive that all
