    it is applied by the elastic bandage, as now described, traction being always made with the unrolled part of the bandage, over the shoulder from front to bach, this subclavicular displacement is prevented. To Fig. 2. prevent the outward displacement I carry every alternate turn under the opposite axilla. By this means the roller bandage is held in place absolutely, even without care from an assistant. II. A New Means op Ascertaining whether the Bladder is Ruptured by Injecting Filtered Air into it.^ This, also, I have had, as yet, no means of testing in the living body. When using Senn's hydrogen test, on an animal recently, the idea occurred to me that it would be an excellent means of ascertain- ing the fact of rupture or non-rupture of the bladder. In order, how- ever, to make it more available, the following modification suggested itself to my mind : 1. Introduce the catheter and empty the bladder of any urine that may be present. 2. Connect the catheter with an ordinary Davidson's syringe. This should have been disinfected. Over the distal end of the syringe a • The subject-matter of this paper had been in my mind for some weeks, but on the very day on which I wrote it, I read a reprint of a paper by Dr. T. S. K. Morton, from the Journal of the American Medical Association, January 4, 1890, in which I found tliat he had already made the suggestion to use insufflation of hydrogen for a similar purpose. I was not aware until then that it had been suggested before. Filtered air seems to me, for the reasons stated, to be much simpler, and therefore more useful, than the njethod suggested by Dr. Morton.
