APPLIED CHEMISTRY.-The application of Chemistry to the arts and manufactures is taught by lectures and text-book. Whenever it is practicable, the actual products are exhibited to the students, and the manufacturing processes reproduced in miniature. Attention is drawn to the scientific relations and connections between the various manufactures. The great losses by imperfect methods of manufacture and by waste products are pointed out, and the student is taught to see the true economy of production. Illustrative of the lectures visits are made to various manufacturing establishments, of which there are a number in and about New Brunswick, and an opportunity is given to see manufacturing operations in actual working.

PRINCIPLES AND THEORIES of Chemistry having recently developed in a very remarkable way, form a most important branch of Chemistry. Accordingly, the subject extends throughout the Senior year. The instruction begins with a discussion of the atomic weights and the general chemical properties of gases. Then liquids and solids are considered from a chemical point of view, particular attention being paid to chemical action in solution. The course is so arranged that at the end students have a clear idea of modern chemical thought. Owing to the exceedingly careful observations required, few experiments can be performed in the class-room, but the student is encouraged to become more familiar with the subject by experiments at his desk.

After finishing experimental organic chemistry, the student takes up work for his thesis chosen by him, but subject to the approval of the instructor.

MINERALOGY is taught in the Junior year. In the second term there is a course of lectures in Descriptive Mineralogy, in which the general characters of minerals are discussed, and some of the most important species are carefully studied. Special attention is paid to CRYSTALLOGRAPHY, as being one of the most distinguishing characteristics, and therefore much used in Determinative Mineralogy, which occupies the third term. In this part of the course the student learns to make the tests by which minerals are distinguished from each other, and becomes familiar with their differences by actual handling and comparison. In this course use is made of the College collections, supplemented by the private collection of the Professor in charge.

Geology is studied in the first and second terms of the Senior year. A text-book is used, but each lesson is explained in advance and fully illustrated by the use of specimens, with which the College is abundantly supplied.

COURSE IN ELECTRICITY.

This course is nearly the same as that in Engineering, Physical Laboratory practice being substituted for Railroad Curves, BridgeBuilding and Geodesy, and for part of the afternoon work in Draughting. This preparation enables graduates to take such positions as do not demand the full mechanical and mathematical equipment of a professional electrical engineer. And those who intend to pursue Electrical Engineering after graduation are furnished with the necessary practical basis. Manual skill and preference for mechanical details are prime requisites for electrical pursuits, hence, those who enter the course will be required to do the most exact work possible, and expected to show cheerful patience in tedious manipulations.

The Physical Laboratory is provided with engines, motors, dynamos and testing apparatus.

COURSE IN BIOLOGY.

Students electing this course must divide their time nearly equally between three departments, viz.:

ANIMAL BIOLOGY, first and second terms; BOTANY, second and third terms; ENTOMOLOGY, first and third terms. Agricultural and Classical electors follow the same general subjects as the Biological electors for corresponding terms. The course is recommended as introductory to medical studies or special biological branches of education or investigation.

DEPARTMENT OF ANIMAL BIOLOGY.-Human Anatomy, Physiology and Hygiene is a required study during the first term, Freshman year. Instruction is given by means of lectures, demonstrations, charts and Auzoux models. The aim is to make the student see the importance of a knowledge of lower forms of life to a comprehension of human biology. Students applying for advanced standing should offer satisfactory evidence of the mastery of such a text-book as Martin's "The Human Body " (Briefer Course), or its equivalent.

ZOOLOGY is a required study during the second term, Freshman year. The method of instruction is by means of lectures and demonstrations of charts, specimens and models. Some laboratory work is done in the class-room. The object is a general survey of the great groups of animals, their general structure and affinities, which may serve as introductory to the study of Historical Geology pursued later, and also may enable the student to appreciate the more popular biological discussions of to-day. Those who enter higher classes without pursuing this course must give satisfactory evidence of mastery of Orton's "Comparative Zoology" or some work on zoology of at least equal grade.

The elective work begins in the Junior year with General Biology. This is mainly in the Laboratory, and is pursued by means of microscope and scalpel. The student sketches and describes the objects studied. Supplementary lectures are given. Each student provides himself with Parker's "Lessons in Elementary Biology " and a small case of instruments. Other apparatus, microscopes and materials are provided in the laboratory, for which a fee is required. The following subjects are studied in the order mentioned:

1. General Biology of Plants.-First half, Fall term, Junior year. Topics: Fermentation (Yeast), Fungi (Mucor, Penicillium), Bacteria, Algae (Pleurococcus, Hæmatococcus, Spirogyra), Chara, Moss, Fern, Alternation of Generations in Higher Plants.

2. Biology of Invertebrated Animals.-Second half of Fall term, Junior year. Topics: Protozoa (Amoeba, Vorticella, etc.), Cœlenterates (Hydra, Hydroids, Sponges), Echinoderms (Starfish), Vermes (Earthworm, etc.), Molluscs (Oyster, Clam, Snail), Arthropoda (Lobster).

3. Biology of Vertebrates.-Winter term, Junior year. Topics: Fish, Frog, Turtle, Pigeon, Mammal (Cat or Dog).

4. Embryology.-Fall term, Senior year. The subject of Comparative Embryology is introduced by a practical study of the development of the hen's egg, artificial incubation being used. This course is intended, also, to supplement the work on Invertebrate Biology of the Junior year.

5. Osteology.-Fall term, Senior year. The subject of Comparative Osteology is introduced by a detailed study of the skeletons of the domesticated animals.

6. Comparative Anatomy.-Winter term, Senior year. Vertebrate Anatomy, introduced by the careful dissection of a mammal, is now offered as supplementing the Vertebrate Biology of the Junior year.

7. Histology.-Winter term, Senior year. In connection with the careful dissection of a mammal, the histological and technical training previously gained is now greatly extended by a special microscopical study of sections of the various organs.

8. Economic Zoology.-Winter term, Senior year. The principles previously acquired are now applied to practical questions, and such topics as the Laws of Heredity and of Stock-Breeding are discussed in a way to show how abstract truths can be subjected to economic application.

BOTANY.-The study of Botany, two hours a week, begins in the third term of the Freshman year, and the ground covered is embraced by "Gray's Revised Lessons." In connection with the text-book work each student makes drawings and descriptions of leaves, stems, roots and other parts of plants. This is followed by a thorough study of the flower from living specimens gathered in the field. The terms used in Descriptive Botany are dwelt upon so that each member of the class becomes familiar with the methods of determining the botanical names of plants, and acquaints himself with the relationships of genera and orders.

Laboratory study in Botany begins in the second term of the Junior year, and students then pursue a course in vegetable anatomy with the compound microscope, in which they are introduced to the various kinds of tissues and tissue systems as illustrated in the leaves, stems and roots of the higher plants. In the third term laboratory practice is continued with the histology of the organs of reproduction, and the collecting of plants in the field begun. Each student prepares an herbarium of at least fifty species, all neatly mounted and fully labeled.

The Seniors, in their second term, have a course of lectures upon Vegetable Physiology, special attention being paid to the origin of varieties through cross-fertilization and other causes. In the laboratory each member of the class becomes familiar, microscopically, with the

histology of cryptogams, particularly those best enforcing the principles in Physiology considered in the class-room. The third term is specially devoted to a consideration of those low organisms that are so obscurely known under the general term of the fungous diseases of plants, and embracing one branch of Economic Botany, now called Vegetable Pathology.

ENTOMOLOGY.-In the third term of the Junior year, Entomology will be taught, chiefly by lectures and laboratory practice. Comstock's "Introduction to Entomology" will be used as a text, and during this term a knowledge of the external and internal structure of insects and of their physiology will be given. Especial attention will be paid to the morphological and biological side of the science. In the Senior year the system of classification will be given, and the students will be required during laboratory hours to prepare, classify, and arrange collections, in part made by themselves. A very full collection of the insects of the United States will assist in acquainting the student with the family types. The aim will be to give such a knowledge of the subject as a whole, as will enable the student to specialize without further assistance should he desire to continue the study at the conclusion of the course.

WINTER LECTURE COURSE IN AGRICULTURE.

January 11th to February 19th, 1892.

The New Jersey State Agricultural College has established a sixweeks' Lecture Course in Agriculture, which is designed to teach those general principles which underlie reasonable farm practice, and their adaptation to the various lines of farming. The course, while primarily intended for farmers' sons, will also be open to such farmers of the State as may desire to attend. In the preparation of the course it has been the aim of the College to make the instruction scientific in its character, but of such a nature as to be directly applicable to the every-day work of the farm. It will embrace the following subjects:

Agriculture.
