Chloride of Lime.This agent was employed in but two experiments ; in these it socompletely failed to manifest any retarding action upon the growthof bacteria in the pulps that it was discarded for further experiments. 3. Peroxide of Hydrogen.Pulps treated with peroxide of hydrogen showed signs of putrefac-tion in from two to eight days, and on opening emitted an exceedingly EXPERIMENTS ON THE COMPARATIVE VALUE OE ANTISEPTICS. 597 intense putrefactive odor. On plates of nutritive agar-agar they soonbecame overgrown with bacteria. This is just what we should expect;this agent brought into contact with the pulp soon decomposes, andbecomes then absolutely inert. It may be advantageously employedfor cleansing root-canals, but not for preserving non-extricable portionsof pulp-tissue against future decomposition. Fig. 4.

Fig. 4.—Plates with Pulps from Calves Teeth. After treatment with /3-naphthol (a),sulphate of copper (6), oil of peppermint (c), campho-phenique (d), sozoiodol (e). The whitishzone around b is due to a precipitate produced by the copper salt, and not to a growth of bacteria.At c we see the cotton on which the oil of peppermint was applied also surrounded by a slightgrowth of bacteria. (In this illustration as well as in Fig. 8 the artist has made the agar-agardark and the growths of bacteria light). 4. Sozoiodol Salts.The salts of sozoiodol (a derivative of carbolic acid, having theformula C6H4I2S04) having lately, after the manner of all new anti-septics, received such unlimited praise for their antiseptic, non-poison-ous, non-irritating, and altogether desirable qualities, have also begunto be introduced into the dental practice. Pulps treated with thepotassium salt (kalium sozoiodolicum) showed no difference fromthose treated with water (Fig. 4, e). The sodium salt showed a sligh
