O F L O N D O N ,
(T o one o f whose lamented Vice-Presidents the
fir st Volume has already been consigned), I presume
to dedicate this result o f the labour o f twenty-three
years, and I beg o f them to accept o f it as a grateful
testimony o f esteem fo r a Society in which I have
long been honoured with a name. This tribute o f
gratitude is more particularly due to them, as from
the President and many o f the Members o f the
Society I have received the most material assistance.
