The Respiration in Pressure on the Brain. By Dr. Landgraf.—Dr. Landgraf calls attention to the state of the respiration, in cases of cerebral pressure. It is frequently not stertorous and labored, as described in books, till the agony; but it is interrupted; that is to say, after from six to twelve tranquil and easy respirations, a long pause insues. The author details cases in proof of the existence and diagnostic value of this sign.—Ibid., from Deutsche Klinik, 1852, p. 89.
