In reducing the observations we have employed Schiff’s values for the thermal 
expansion (‘Ber.’, 18, a, 1G05), and the number d{0°/(f) = 1‘0884 for the relative 
density. 
Taking 
= ‘008670 7^3 = ‘003447 rj^ (calculated) = ‘005469 
= 0°‘24 to = 82°‘53 curve) = 35°‘52, 
we obtain tlie formula 
— 15-677 
~ (105‘87 + ’ 
which gives results in good agreement with those obtained by observation.
