Bishop Clark'b subject was "The Living Machine," which ha treated physieally and metaphysically, familiiuly and scientiflcally. The human organism was denionstrated the most perfect and wonderful piece of machinery, of complex construction, but capable of reproducing itself, and of repairing damages- with the aid of the Medical Faculty. It is a laboratory, converting gnses into fluids, öuids uto solids, and viee versa; it is an engine of great power. The connection between the body and ihe soul was traced and their material dependonce pointed out. The Bishop has ';a voice under peifect cojitrol, his illustrations were happy, his science made plain, and thelectureabounded with passages of eloquence which thrilled every person in the l-.rge, audience. Tliosc heard it will long euiember it with nleasure.
