This Report may now fitly be brought to a conclusion by calling 
fresh attention to a notice, prefixed to the Prospectus of Lectures for 
the Session 1854 — 55. — " The Society was constituted for the 
purpose of training its members in habits of investigation and 
thought, as well as affording opportunities for acquiring facility 
of expression in the delivery of the sentiments to which subjects 
under discussion might give rise." By keeping these objects con- 
stantly in view, the Plymouth Institution cannot fail to steadily 
progress in the favour of a discerning public.
