was formed and from that after saturation with sulphuretted hydro- 

 gen and evaporation of the filtrate the free acid was obtained as a 

 thick syrup-like liquid with strong acid properties. To further char- 

 acterize the acid the following salts were prepared : 



Lead octylhenzol sulphonate. — This salt was gotten by treating the 

 aqueous solution of the acid with pure lead carbonate. It crystal- 

 lized in small microscopic needles which were easily soluble in 

 water. 



Analysis— o. 1 71 5 g. of the salt yielded by 130° o.oi2ig. water; 0.1715 g. 

 of the salt yielded 0.0640 g. lead sulphate, equivalent to 

 0.04373 g. lead.

Barium octylhenzol sulphonate. — This salt was prepared in the 

 same way as the lead salt. Under the microscope it showed thin 

 plates which were easily soluble in water: 



Analysis. — 0.0987 g. of the salt gave by 130'' 0.0023 g- water 0.0987 g. of 

 the salt gave 0.0337 g- barium sulphate, equivalent to 0.01983 

 g. barium.

Silver octylhenzol sulplionate. — This salt was prepared from the 

 freshly precipitated silver oxide and the aqueous solution of the 

 acid. Under the microscope it showed thin plates which were easily 

 soluble in water. 



Analysis. — 0.1009 g. of the salt gave by 130 0.0046 g. water 0.1009 g- of 

 the salt gave 0.0363 g. silver chloride, equivalent to 0.02736 

 g. silver.
