to a greater degree than does that with the isotonic salt, while the 

 latter combination probably promotes the growth of granulations 

 more than does the former. These solutions on contact with the 

 wound cause a burning sensation which quickly passes away. 



The healing of blind tracks of soft parts may be facilitated by 

 injecting the tracks once in 6 or 8 hours through tubes having no 

 punctures, introduced to their bottoms, for which purpose the 2 

 per cent, chinosol solution having the 5 per cent, salt content is 

 probably the preferable solution of the two. The tincture of 

 chinosol (ty chinosol 2 per cent, and sodium chloride grains i ss 

 to the ounce in 80 per cent, alcohol) has seemed particularly ad- 

 vantageous for the healing of blind fistulae in ano, though with a 

 different technic, it being injected into the track two or three times 

 at 15 to 30 minute intervals each day. 



For the control of sepsis in a draining empyema case, the solu- 

 tion of 2 per cent, chinosol with the 5 per cent, sodium chloride 

 content is recommended, one ounce of which may be injected into 

 the cavity to be retained by posture, following a preliminary 

 washing with salt solution. In one case the use of a 5 per cent, 

 salt solution for the preliminary washing, seemed to avail more 

 toward cicatrization and healing of the wound than had normal 

 saline. Wright has shown that a preliminary wash of a pus-se- 

 creting surface with physiological salt solution to remove the 

 albuminous substances, gives an aftercoming antiseptic an oppor- 

 tunity to reach the bacteria. Before dressing a wound, the sur- 

 rounding skin is first wiped with McDonald's solution (Alcohol 

 60 parts, acetone 40 parts, to which 2 per cent, of pyxol is added). 



First-aid treatment is effected either by packing the wound with 

 gauze saturated with a solution of chinosol iv grains to the ounce 

 and 0.85 per cent, sodium chloride, which may be left in place 

 for 24 hours before repairing or redressing the wound, when the 

 same solution should be used again, or by simply sponging the 

 wound freely with the solution during the operation for its imme- 

 diate repair. The above gauze pack, after remaining in a fresh 

 wound for 24 hours, often adheres to well nourished tissues. 

 Hypertonic salt should not be used in a fresh wound which is to be 

 sutured. In both old and fresh wounds which gape, it is advisable 

 to interpose a piece of rubber tissue between the gauze which
