O= —3368 * d4+2284*p+1011 * n—14683 * 144424, 
and by dividing by 14683 
O= —0'22944 - d+0°15555 *p+006885 *m—i+0°30130 (2). 
By multiplying this equation successively by the coefficients of i in 
the equations C, and adding these new equations to the corresponding 
ones of the system C, I obtained the system of equations D independ-
