886 PROF. W. H. MILLER ON THE CONSTRUCTION OF THE NEW STANDARD POUND. 
(Q with each of the weights I+K+A, I+L+B, I+M+F, I+N+A; each of the 
weights K, L, M, N with I ; I with A+B+F+A+Z; each of the weights A, B, F, 
A with Z+0. The value of 0 in terms of I was known from comparisons made for 
a different purpose. The weights A, F, A consisted of the auxiliary platinum weights 
A, C, D, used in forming the lb. of 7000 grains, with the addition to each of a three 
rouble platinum coin and a little more than 33 grains of platinum wire weights; 
B of the auxiliary platinum weight B together with the platinum weight V+0'03 gr. 
which had been used with K + L in weighing the kilogramme des Archives. Z con- 
sisted of the platinum weights F, G and 30'85 grains of platinum wire weights. 0 was 
made up of the platinum W’eights L and M of nearly 80 grains each, one of the 1-grain 
weights of the two Robinson’s balances, used by turns, and one of the ten weights 
Q of 0‘64509 grains each, also used by turns. 
The zero of the scale of the barometer was 305 mm. above the middle of the 
weights, 0’03 mm. must therefore be added to the observed value of F. 
Let l^=I-f K+A, L-f B, F, Jl5=I+N-f A.
