The opening made by the trephine should be an inch in dia- 

 meter. Sometimes, however, success is best attained by forcing 

 the fluid up the nostril from the natural opening at the 

 bottom. 



The Syringe used for the purpose should not hold less than 

 half a pint of liquid ; and it should also be provided with a 

 pipe six or eight inches long, made of india-rubber, or of a 

 strong, soft, and flexible material of another kind. This should 

 be passed up the nostril with the greatest care ; otherwise the 

 turbinated structures, and their investing mucous membrane,

Amongst the best fluids to inject are — Cold "Water, Tinc-

 Tincture to a pint of Water. 



Chloeide of Zinc. — Use this remedy in the proportion 

 of 1 drachm of the Salt to 12 or 14 ounces of Water. 



Tinctuee of Myeeh and Aloes. — Use this remedy in 

 the proportion of 1 ounce of the Tincture to 3 or 4 ounces of 

 Water. Its efiect, when injected up the nostril, is not only 

 that of a stimulant upon the mucous membrane, but the Myrrh 

 and the Aloes form a sheath upon the parts diseased, which 

 greatly favours recovery. 



Diet. — The Diet of the patient ought to be generous. 

 Beans, Oats, Malt, Bran, and good Hay should form the daily
