Injected blood of patients suffering from pneumonia into guinea-pigs. “Nasse and Rosenthal, but especially Leyden, had, a few years ago, studied the effects of pressure and agitation on the functions of the brain mass. Leyden injected a solution of sodium chloride between the skull and dura mater. A more extended series of experimental investigations was subsequently undertaken by Dr. F. Pagenstecher. Pagenstecher injected a mixture of white wax and tallow heated to 50° C. between the skull and dura mater of dogs. As regards the sensibility of the dura mater, Leyden and Pagenstecher differ.”--Bartholow’s “_Functions of the Human Brain_,” _Amer. Journ. of Med. Sci._, April, 1874, pp. 305-306. =Lindgren, H.
