The Second Volume of the Reverend Dr. DUNCAN'S Sacred Philosophy
of the Seasons, is devoted to Spring; and is an provement, perhaps a considerable improvement, upon the first The subject is more genial, more varied, and admits of a wider extent of theological illustration and religious enforcement, than the sadder thence of Winter. The causes of the phenomena of nature-
" In the pleasant spring, When every thing
Is bursting from the ground"— the organization and reproduction of vegetables—the animal sys. tem of living creatures—the instincts connected with their gene. ration, and with the parental feelings—are all rich in curious and instructive facts; and Dr. DUNCAN, assisted by some friends of a kindred spirit, has brought together a very interesting collection of them from the works of modern_ naturalists, as ROGET, BELL, and KIRBY. The author also treats of the nature and management of soils—the principles of agriculture—the effects of cultivation both upon land and plants; varying, as before, his six daysof natural theology by a religious discourse on the seventh day, de. rived from the character of his previous subjects—as Christian regeneration finds an appropriate place in the midst of the section on the reproduction, &c. of animals.
