‘Vapor of water, ‘4750 0°2950 
The author directs attention to the very remarkable fact that the spe- 
cific heat of the vapor of water, namel 0-475, is very nearly the 
ment of pure hydrogen gas. Similar decompositions occur with angelic 
and oleic acids and may be represented by the following equations. 
CioHs01+2KO, HO=CsH:30s, KO+Cc6H;s0s, KO+2H 
CseHs20s+2KO, HO=CiH20s, KO4+Cs2H310s, KO+2H 
These remarkable reactions not merely demonstrate the existence of 
@ series of acids homologous with oleic acid, but exhibit the relations 
t 
excess of eaustic potash yields acetate and benzoate of potash and hy- 
drogen. The equation is 
‘Thence it would appear that cinnamic acid stands in the same relation 
to benzoic acid that acrylic acid does to formic acid, or oleic to ethalic 
( ween acid, and tans ok a further analogy between the acetyl

ew organic radicals containing Tin.—Léwic has communicated 
the results of an elaborate investigation of the products resulting from 
the action of iodid of ethyl upon alloys of tin and sodium. ‘These re- 
sults are of great interest, and throw much light upon the nature and 
structure of organic radicals. The alloys of tin and sodium employed, 
were obtained by simply melting tia in an earthen crucible and adding
