Ihis is in harmrony with the fact that magnesium amalgam does
not form when magnesium and mercury are brought together
at ordinary temperatures;' it requires a higher temperature in
order that the union of the re-tals will take place.
  The view that solutions are chemical combinations of solvent
and solute may seen, somewhat antiquated at the present time
when purely physical conceptions of solutions are in predomi-
nence.  But this older view is still held by eminent chemists
and physicists, for it gives an adequate cause for the process of
solution, for the thermal changes accompanying the latter, and
for the fact that (exclusive of the mass) the properties of a
solution are never found to be quite equal to the sum of the
properties of solvent and solute. -Moreover, facts known at
present concerning both dilute and concentrated solutions are
entirely compatible with it, and it will no doubt prove a most
valuable aid in further research.

 'At ordinary temperatures the affinity between the metals is not
able to overcome their cohesions. Compare the work of Wanklyn and
Chapman on magnesium amalgam in the Jour. Chem. Soc. (2) 4, 141.
