In my inaugural lecture, I stated that while holding this professorship I should direct you, in your practical exercises, chiefly to natural history and landscape. And having in the course of the past year laid the foundational elements of art sufficiently before you, I will invite you, now, to enter on real work with me; and accordingly I propose during this and the following term to give you what practical leading I can in elementary study of landscape, and of a branch of natural history which will form a kind of center for all the rest-Ichthyology.
