What has’ already been said when speaking of the results contained in Tables XI., 
XII., and XIII., will of course apply here. In Table XIV., the values in the columns 
headed r 100 °— r 1 ^ and r 0 °— do not agree in all cases ; and at the first glance we should 
be inclined to suppose that the law was not as correct for these alloys as for those given 
in Table XVI. ; but this is only due to slight errors in the determination of the resist- 
ances, &c., for a small percentage difference in these numbers will cause a very marked 
one in those under the headings r IOO ° — / 100 o and r 0 0 — r[o . If, on the contrary, the values 
in the columns r, ou ° — r 0 ° and r' 100 °— in Tables XIV. and XVI. be compared with each 
other, it will be seen that those in Table XIV. agree together quite as well as those in
