thought that this very probably was nothing more than a decomposition 
product—the result of too intense heating—I treated a second portion of 
the silver salt in a similar manner, taking care, however, not to let the 
temperature become too great. The thermometer indicated 103°C for 
three hours. The color of the liquid in the tube was dark red. The tube 
was opened and the liquid filtered off from the silver iodide which was 
washed with alcohol, and the solution then evaporated almost to dryness. 
Upon allowing the solution to stand over night, I observed the next morn- 
ing that the liquid had solidified perfectly. The mass was removed from 
the beaker glass, reduced to a fine powder, and after being exposed to the 
air for several days, it was dissolved in alcohol. 
Upon warming the solution the mass dissolved readily, and upon cool- 
ing the compound separated out in long, colorless needles. These fused at 
48°C, upon recrystallization I discovered that the fusing point remained 
constant, and the substance was then subjected to an analysis.

Cahours (Ann. Chim. Phys. 10, 343) mentions a methyl] ether of chlor- 
salicylic acid produced by the action of chlorine upon methyl] salicylic acid, 
It was difficult to obtain it pure. I believe this to be entirely different from 
my compound above described.

I have succeeded in forming this compound, but as I have never had it 
in pure enough condition to make an analysis, I give merely my experience 
in its formation. Time and again I heated the pure silver salt with per- 
fectly pure ethyl iodide, but when I searched for the resulting ether, I ob- 
tained nothing more than a dark heavy liquid that remained in this condi- 
tion under all circumstances. That this was nothing else than a decompo- 
sition product I learned afterwards. High heat is not required for the 
formation of this compound, it is produced just as soon as the silver salt 
and ethyl iodide are shaken well with each other, the reaction is indicated by 
the increase of temperature that may be noticed by placing the hand on the 
vessel containing the mixture. <A portion of the silver salt with ethy]
