SOLID FATTY ACIDS OF COCO-NUT OIL. 281 
From the acid obtained from ether, marked H, boiling point 230° to 240°, 
both a baryta and a lead salt were prepared. 
Baryta salt, marked H, gave 28°53 per cent. Ba. 
Analysis of lead salt, marked H. 
03805 grammes lead salt gave— 
060625 grammes CO, = 43°45 per cent. carbon. 
0252 i HO "7-3 sa hydrogen. 
0°20225 grammes lead salt gave, after ignition with sulphuric acid,— 
0:10775 grammes PbSO, = 38°03 per cent. lead.

Barium caprate (C,,H,,0,).Ba requires— 
28°60 per cent. barium. 
Analysis of baryta salt, marked N, from ether boiling point, 280° to 285° C. 
This salt is anhydrous. 0:233 grammes salt, exposed for two hours to 100° 
C., did not lose in weight. 
Three estimations of barium gave a mean of 25°40 per cent. Ba. 
Estimation of carbon and hydrogen; combustion made with oxide of 
copper.
