��Rapid Breathing as a Pain-Obtunder in Minor Surgery, Obstetrics, and the General Practice of Medicine and of Dentistry. Bv W. G. A. Bonwill, D. D. S. Pp. 16.
The author describes some experiments by which he has been led to assert that be can produce, from rapidly breathing common air, a similar effect to that from ether, chlo- roform, and nitrous oxide gas, in their pri- mary stages, and can thus render patients sufficiently insensible to acute pain from any operation where the time consumed is not over twenty or thirty seconds. While the special senses are in partial action, the sense of pain is obtunded, and in many cases completely annulled, consciousness and gen- eral sensibility being preserved. He has used his method satisfactorily in his dental practice for four years, and refers to Dr. Hewson as having used it in obstetrics for three years.

Annual Report of the Chief-Engineer OF the Water Department of the City of Philadelphia for the Year
1880, Presented to Coimcils, May 5,
1881. Philadelphia: John D. Avil & Co. Pp. 128.
A noteworthy feature of this report is that it seems to show that the water-power of the Schuylkill has been highly overrated, and has not half the value at which it has been estimated ; hence attention should be diverted from water-power and turned to steam-power as a means of propelling the machinery by which a steady supi)ly of water is to be secured from such works as those on which Philadelphia depends.
