It Vv'ill be seen that, with the single exception of the observation at 16°'8 in 
Series I., the agreement is extremely satisfactory. The vaponr-pressures have also 
been determined by Dr. A. Eichaedson by our method (‘ Chem. Soc. Trans.,’ vol. 49, 
p. 763) with concordant results.

* As in our former memoirs, the specific gravities are referred to -neater at 4°, and are therefore true 
masses of one cubic centimetre.
