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. 



Gill-Nets in the Codfishery : A Descrip- 

 tion of the Norwegian Cod-Nets, with 

 Directions for their Use, and a History of 

 their Introduction into the United States, 

 By Captain J. W. Collins. Bulletin, 

 U. S. Fish Commission, I. 1881. Pp. 

 1*7, with Nine Plates. 



The Fish Commission, believing the gill- 

 nets to be a valuable fishing apparatus, has 

 exerted itself to have them introduced and 

 generally used in the United States. The 

 present pamphlet is a part of its effort. The 

 title furnishes a sufficient index to its read- 

 ing contents. The plates exhibit the con- 

 struction and method of setting and using 

 the nets, to the minutest detail. 



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.

 The figures in the plates are representations
