Eleven P. M. Pulse quite imperceptible; is sinking fast; venous injections attempted a third time, but desisted from as it was not productive of the first good effects. Both pupils much dilated. Died at two A. M. 14th. _Dissection fifteen hours after death._--On exposing the brain and spinal marrow, but before opening their investing membranes, the least pressure with the fingers on the middle of the hemispheres of the brain caused a remarkable undulating down to the middle of the back, showing the existence of a fluid beneath the membranes, and on opening them about two drachms of pure serum flowed out. The surface of the brain was rather vascular, and the blood in the most minute vessels particularly bright. A few ecchymosed spots on its surface. All the other viscera were found healthy. The urinary bladder contained about half an ounce of urine. THOMAS CRAIGIE, M. D. _Leith, 26th May, 1832._ No. 6. _List of Queries addressed to Drs.
