very little if at all. Granted that these iodine-containing solutions 

 diffuse deeper than the solvents, then it appears that the latter by the 

 addition of iodine obtain a higher diffusibility. The power of diffusion 

 of alcohol was far weaker than was formerly supposed, at least with 

 respect to coagulation of granular tissues with numerous cells. Dakin 

 and Buret's hypochloride solutions did not have a very penetrating 

 bactericidal effect under these conditions. The members of the phenol 

 group showed, more or less, bactericidal power ; carbolic acid was the 

 best antiseptic, as it had less effect on the agar. The organic colouring 

 pigments were remarkably diffusible. Malachite-green was the most 

 diffusible of all, but the authors preferred brilliant green, as the latter 

 hardly ever precipitated the albumin in agar. The diffusibility of most 

 antiseptics was proportional to the power of concentration, but with 

 hydrogen peroxide there was an inverse ratio ; the 5 p.c. solution 

 penetrated farther into agar than the 10 p.c. solution. J. E.
