oaportunity to examine and taste numerous samples
OF meat, prepared in many different ways that had

months at the Summer temperature of Florence,

PROPERTIES OF FUslBLE AILoYs.-Mr. Walter
Spring has presented to the Academy Of Sciences
of Belgium memoir On the dat2tlon and specific
heat of fsible alloys, and their relations with the
law of the capacity of heat of atoms of simple and
compound bodies. THIS memoir which has been
accepted for publication by the Academy, is both Of
theoretical and experimental nature After re-
viewing tle great works Of DUlong Petit Regpauit
Nenuiann and Others the author remarks that thus
far we have generally admitted that specific heats
of bodies depend simply the temperature but
that he thinks If more likely that they should do
pend upon two factors, viz, volume and tempera-
fnre. After Developing his views tceo'en'a1yi ho
