known to beseptic, or thrown away. * I have found by computation that the pressure exerted upon each squareinch of the interior of a fruit jar tightly sealed and heated to 2000 F. in awater-bath is equal to about that of two atmospheres. 17G GEORGE RYERSOX FQUEER, M.D. The following advantages are claimed for this method: i. Thecatgut is rendered absolutely aseptic, after all handling in the prep-aration has ceased. 2. It is hermetically sealed by glass againstall infection. 3. It is cut in suitable lengths for use. 4. Thesurgeon may resterilize the gut, if he desires, by placing it in an ovenheated to 2000 F. for one hour. 5. The quality of the gut is not im-paired, but on the contrary it is rather improved by boiling alcohol. In employing this method (boiling in alcohol under pressure)for the sterilization of catgut, I wish to warn against attempting tocombine the same with the use of chemical germicide. The addi-tion of any of the usually employed antiseptic or disinfectant agents

to the alcohol, or the placing of the gut therein, either before orafter boiling in alcohol, will surely result, as I have repeatedlyproved by trial, in disintegration of the gut. I am indebted to the J. Ellwood Lee Co., of Conshohocken,Penna., for carrying out my suggestions in perfecting the asepticcatgut ligature tube. * * At my request Drs. Meade Bolton and Slee made a careful bacteriologicalexamination of the contents of these ligature tubes at the Hoagland Laboratory.After sterilizing by heat the portion of tube to be broken, the catgut strandswere removed by means of a sterilized needle from the tube, and placed inculture tubes containing various media. Some of these tubes were placed inan incubator and kept at body heat, while others were exposed to ordinaryroom temperature. At the end of a week the catgut was found to be absolute-ly free from all forms of germ life. This confirms the observations made byDr. Hodenpyl. N. Y.
