the frequent shout, OF applause which greeted
the lecturer. In 'scr, the walls echoed and re-

We were highly delighted with the lecture In
fact, Professor n Is every thing we could wish
an exceedingly h1ent and graceful speaker,
poetcal and choice his language, complete
master OF his subject, and possesses the happy
tact OF making even statistical details interest
