The Dental cosmos . hat iodoform is farfrom possessing the marked antiseptic properties formerly attributedto it. This assertion is fully affirmed by my experiments.

It has been maintained that when products of putrefaction come intocontact with iodoform iodine is set free, and that, accordingly, insuch cases where decomposition has already begun, iodoform is par-ticularly efficient in arresting it. To test the accuracy of this claim apulp was infected and, after putrefaction had set in, rolled in powderediodoform and put into a glass tube. After nine days, it was taken outand placed on an agar-agar plate, where in twenty-four hours itbecame completely overgrown with masses of bacteria (Fig. 3). Fig. Fig. 3.—Plate of Agar-Agar with Three Pulps, a had been treated with phenol; itremained sterile, b had been rolled in iodoform ; it nevertheless soon became surrounded by agrowth of bacteria, c, also treated with iodoform, is overgrown by micro-organisms. I consider iodoform as one of the most worthless substances yetintroduced for the purpose of treating the condition under considera-tion. That this fact has not been revealed by practical experiencelong ago is in part due to the circumstance that iodoform is nearlyalways employed in conjunction with some other material, such ascarbolic acid, oil of cloves, etc. 2. Chloride of 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 treated with peroxide of hydrogen showed signs of putrefac-tion in from two to eight days, and on opening
