The instruction will be conducted by the pro-fessors and assistants of the school, and will consist of lectures andexaminations on the following subjects; viz. Mineralogy, Geology,*Botany, Zoology, Chemistry, Experimental Philosophy and PracticalMathematics, particularly Land Surveying, Harbor Surveying andEngineering. Applications will be made, by direct inspection ofrocks and minerals in place, plants and minute animals in their nativelocalities, the works of the engineer in actual operation, the labors ofthe agriculturist, he. One of the largest boats belonging to the flo-tilla is to be furnished with a suitable chemical and philosophical ap-paratus, and cabinets in mineralogy and geology; a reading room,also, is intended to contain such scientific books as are deemed re-quisite for the course. Students of the course will be taught
