Marshall. } 484 [April 5, 
After the amide has been dissolved in nitric acid, water is added to the 
solution, which causes the precipitation of the nitro compound in yellow 
flocculent masses. These I brought upon a filter, washed well with cold 
distilled water and then boiled up with potassium carbonate. By strongly 
evaporating the solution the potassium salt crystallized out. After purifi- 
cation the acid was set free with dilute hydrochloric acid. The acid re- 
crystallized from water showed the constant fusing point 192° C. In cold 
water it is only slightly soluble and dissolves readily in large quantities of 
warm water. It crystallizes from aqueous solutions in long, slightly 
yellow-colored crystals—needles. 
The following salts were made and analyzed : 
SALTS. 
PotasstumM MONOCHLORNITROSALICYLAMIDE. 
Cr NO; ChEOMREe COUN EE: 
I obtained this by boiling the free acid with a slight excess of potassium 
carbonate. From the concentrated filtrate the salt deposits in long yellowish- 
red needles. Easily soluble in water. 
Potassium Estimation. 
.0460 Grm. air-dried salt were evaporated in a platinum crucible with 
sulphuric acid. There resulted .0146 Grms. K, SO, = 14.93% potassium.

Barium MONOCHLORNITROSALICYLAMIDE. 
(C, H, C1NO,O CON H,), Ba. 
I obtained this salt by boiling the free acid with barium carbonate and 
evaporating the filtrate. The salt crystallizes in short, thick needles, of a 
deep blood-red color. It is only soluble in a rather large quantity of boil- 
ing water. 
Barium Estimation. 
.2006 Grm. well dried salt were dissolved in water and the barium pre- 
cipitated as sulphate. Obtained .0805 Grms. Ba SO, = 23.66% Ba.
