between 0° and 100° C. As the result of four experiments, the 
specific heat of pure beryllium was obtained as 0°4107, 0°4144,

if the atomic weight be assumed as 13°8, it follows that beryllium 
belongs, not to the magnesium group, but to that of aluminum, 
that its atomic weight is 13-8, its specific heat 0°4079, and that 
llium oxide is Be,O, as Berzelius claimed.— Ber. hem.
