SOLID FATTY ACIDS OF COCO-NUT OIL. 283 
Agreeing with barium cocinate (C,;H,;0,).Ba, which requires— 
Carbon, . : : : ; : 55°41 
Hydrogen, ‘ A : : : 8°88 
Barium, . i ‘ 3 " ps 24°33 
The last analyses to be mentioned are those of baryta salt, marked P, from 
ether, boiling point 290° to 300°. 
Analysis shows this salt to be the same as O. 
Two estimations of barium gave— 
25°10 and 24°63 per cent. barium. 
Estimation of carbon and hydrogen ; combustion made with chromate of 
lead. 
I. 02095 grammes baryta salt gave— 
0:407 grammes CO, = 52:98 per cent. carbon. 
O1685, 5, HoO=> 8-93 » hydrogen. 
II. 01405 grammes baryta salt gave— 
0:2725 grammes CO, = 52°89 per cent. carbon. 
0°1175 a H,O= 9:28 i hydrogen. 
III. 0°551 grammes baryta salt gave— 
1:0765 grammes CO, = 53°26 per cent. carbon. 
0-412 oe. HO . 8:29 » hydrogen. 
Allowing for carbon retained as BaCO, (as in A, N, and O), these show—-

) To prove that the corrections made in the carbon determinations of these 
| analyses were not only justifiable but necessary, two analyses were made of the 
| same baryta salt P with chromate of lead mixed with one-tenth of its weight of 
fused bichromate of potash, with the following results :— 
I. Carbon, : ° : ; 55°40 per cent.
