DICHLORSALICYLATE OF LEAD. 
CHE Cl. O PbiC Oo: 
Lead acetate was added to a solution of the ammonium salt and the lead 
salt obtained as a white insoluble precipitate, which after being well 
washed and dried was analyzed.

Action oF Nirric AciD upon DIcHLORSALICYLIC ACID. 
Dilute nitric acid has no effect upon the acid. When treated with fum- 
ing nitric acid no change is produced until heat has been applied. After 
dissolving the dichlor acid in this solvent I permitted the solution to stand 
several days, hoping to find the nitro compound separated out by that 
time—this, however, did not occur. Upon evaporating the solution to dry- 
ness, nothing remained, the substance, whatever it may have been, having 
been completely volatilized. A second portion of the acid after treatment 
with fuming, nitric was mixed with a large quantity of water and then 
distilled. The distillate possessed a yellow color, and after neutralization 
with potassium carbonate, was strongly evaporated, then placed in a dessi- 
cator over sulphuric acid. After standing some time minute globular crys- 
tals appeared, but the quantity being so small I was not able to examine 
them, preferring to defer the investigation of this nitro compound, if such, 
until larger quantities of the substance can be obtained. 
CALCIUM OXxIDE AND DICHLORSALICYLIC ACID. 
The acid distilled with calcium oxide yielded an almost colorless oil, 
having a rather pungent odor. The compound was not further examined.

The introduction of the ethyl] radical was first attempted by heating upon 
a water bath a small flask containing the silver dichlorsalicylate and ethyl 
iodide. This, however, failed to produce the desired result. 
Inasecond trial the perfectly dry and pulverized silver salt was placed in 
a tube of Bohemian glass, an excess of ethyl iodide then added, the tube 
sealed and heated in an air bath for twelve hours, the temperature not ex- 
ceeding 135°C. Upon examination a rather large quantity of silver iodide 
was noticed, and the liquid which before heating was colorless was now of 
a reddish-brown hue. The tube was opened and its liquid contents poured
