 mon practice, and attended with much good. The old 

 method of performing this operation is simply to use a 

 syringe, or to elevate the head and pour lotions, etc., into 

 the nose. 



Professor Rey has adopted a very simple and satisfactory 

 procedure. It consists in causing the fluid to rise in each 

 nostril by atmospheric pressure, and when the one division 

 of the nose is thus filled, the liquid passes over, and is seen 

 to flow out at the opposite nostril. In this way the liquid 

 most effectually touches every part of the membrane, and a 

 mild solution of sulphate of zinc or copper, and other seda- 

 tive, astringent, or antiseptic lotion, may be brought in con- 

 tact with the suppurating or ulcered surface. The instru- 

 ment which Professor Rey employs for this purpose is drawn 

 at Fig. 14. The long tube is fifteen inches in length, and 

 one and a-half inches in diameter, expanding and funnel- 

 shaped above, where the broadest part is two inches wide.

The short arm is five inches in length, and the aperture two- 

 thirds of an inch in diameter. Over the short arm is passed 

 a closely-fitting leather ring, four and a-half inches in diam- 

 eter. This serves as the surface over which, and round the 

 short arm, wet tow may be adapted, so that, on introducing 

 the small tube in the nostril, the latter is compressed care- 

 fully on the tow; at the same time fluid is poured into 

 the funnel, and rises in the nasal chamber. If the horse's 

 head be bent in, and held as much as possible in a perpen-
