fession is a thriving one ; its future prospects are most en- 
couraging; it has within itself resources to gratify any rea- 
sonable ambition ; and you may either reap the harvest 
which is sure to follow right endeavours, or leave it to be 
secured by others, whose courage, energy, and perseverance 
entitle them to gather it. 
Another requisite for success, depends upon a sedulous 
and irrepressible devotion to the objects which seriously 
occupy the attention. Happily enthusiasm has been exten- 
sively implanted in the soul, and few are so formed as to 
be without it. When restricted to its peculiar limits, it en- 
hances much the pleasure, and adds greatly to efficiency in 
the performance of respective duties ; in fact, without it, 
even mediocrity can hardly be attained. But I may advance 
one step farther, and assert, that from this principle origi-

and ingenuity, unexcited to legitimate exercise, would be 
expended upon trifles. Nothing great, nothing good, has 
been accomplished without the infusion of an enthusiatic 
feeling, which has led to the removal of difficulties nearly 
insuperable, and brought forth discoveries the most remark- 
able. Genius must be aroused by it, or genius must lie 
dormant and profitless. In every department of knowledge, 
it has been the impulsive instrument of extension ; for the 
love of knowledge and discovery alone, would prove of 
little service. 
Enthusiasm bestowed spirit and animation upon the re- 
searches of Newton, cold and abstract as they may appear

Locke upon the stretch to fathom the depths, and unfold 
the operations of the human intellect. It stimulated Cuvier 
in the exploration of the external forms and modifications 
presented on the surface of the globe, and aided him in 
building up a system of arrangement before unequalled. It 
so completely possessed the control of Davy, as to render 
him untiring in his labours. And it sustained Champoiion
