    infrequently takes place. Sidler-Huguenin succeeded in finding microbes quite frequently in solutions that we had used for some time, and these microbes consisted not only of sarcinse and mold fungi, but also of streptococci and staphylococci which were found to be pathogenic. [Some years ago Dr. E. A. de Schweinitz and the editor made an elaborate bacteriologic examination of the pipets and collyria taken from a treatment case which had been used in ophthalmic practice for some time, and found in the fluids the micrococcus aquatilis, the bacillus liquefaciens, the proteus vulgaris, the micrococcus pro- digeosus, the bacillus implexus, and aspergillus glaucus, as well as staphylococci and streptococci. The proteus vulgaris, the micrococcus prodigeosus, and the bacillus implexus obtained from these solutions introduced into the anterior chamber of rabbits produced a violent in- flammation of the iris and anterior portion of the eye. Inoculations with the other organisms, except staphy- lococci and streptococci, were negative.—Ed.] It is therefore absolutely necessary that the. solutions used at an operation have been recently boiled, and during the postoperative treatment it is also necessary to use sterile solutions. This is not such a simple matter as it would seem. It necessitates, first of all, properly working drop- ping bottles that can be boiled with their contents and in which there is not much danger of a subsequent pollution of the contents. Stroschein, Snellen, and others have busied themselves considerably with the improvement of dropping bottles. As Stroschein's bottle did not suit us altogether, Sidler-Huguenin devised one which presents certain additional improvements, the most important of which is the extra width of the mouth, so that in putting the pipet back in the bottle there is less danger of striking the point against the lip or even the outside of the bottle, an accident that is apt to happen with any dropping bottle hitherto devised. As the outside of the bottle cannot be kept absolutely clean while it is in use, it is always pos- sible that the point of the pipet may be polluted by
