DICHLORSALICYLATE OF POTASSIUM. 
G7 HB, Cl, OH.C:0:0: K. 
This salt was obtained by boiling the preceding compound with a calcu- 
lated amount of potassium carbonate. From a concentrated aqueous 
solution it crystallized in white needles, very much like the salt of Rogers 
described above. After recrystallizing the compound several times and 
then allowing it to separate from a dilute solution I obtained it in almost 
colorless needles, that united to form clusters. 
Analysis proved it to be anhydrous. 
Potassium Estimation. 
I. 0. 2020 Grm. well dried salt gave 0.0710 Grm. potassium sulphate= 
.03181 K—15.75 % K. 
II. .2651 Grm. dried salt gave .0930 Grm. potassium sulphate—0.04117 
Grm. K=15.5% K.

DICHLORSALICYLATE OF SODIUM. 
C,H, Cl, OH COO Na. 
Obtained by -boiling an aqueous solution of the barium salt with sodium 
carbonate and concentrating the filtered liquid. The salt crystallizes in 
broad needles, possessing a slight yellow tinge. It is easily soluble in 
water.

DICHLORSALICYLATE OF MAGNESIUM. 
(C, H, Cl, OH COO), Mg. 
An aqueous solution of the free acid was boiled with magnesium carbon- 
ate and the liquid evaporated to a small bulk. After standing some time, 
small, white crystals appeared; these were very readily dissolved by 
water.
