laboratory of the University Experiment Station. In the sub-basement there are a large constant temperature room, dynamo rooms, the ore crusher room, a large stock room, etc.

Distilled water is conducted in block tin pipe to all the more important rooms on each floor, from a tin-lined tank in the uppermost story where the distilling apparatus is placed. Every student's place is furnished with all the essential apparatus for his general work and with water and gas, and with suction in the quantitative and organic laboratories; oxygen, hydrogen, and air-blast are supplied wherever required, from reservoirs in the basement. The oxygen and hydrogen are made by the electrolytic decomposition of water by means of a dynamo current, the gases being collected in tanks of about fifty cubic feet capacity, and thence piped to the various rooms of the building.

The museum contains collections for the illustration of lectures upon general, organic and applied chemistry. These collections include specimens of the elements, their compounds, and the ores from which they are obtained, a full series of typical organic compounds, and also specimens iliustrating the leading chemical industries, such as the manufacture of the various acids, alkalies and salts, pigments, glass, pottery, soap and stearine, and the chemical processes of bleaching, and dyeing, and photography.

THE CHEMICAL LIBRARY contains complete sets of all the important journals, and is very fully supplied with works of reference and the standard books on chemistry and allied subjects. Such additions are made to it from year to year as are necessary to keep it abreast of the times. It is accessible to all students, under such restrictions only as are necessary to secure it against injury or loss.

The laboratories are open from 8 to 5:30 except on Saturday, when they are closed at 1 o'clock. Instruction hours are from 8:30 to 1, and 2:30 to 5:30.

In this course especial attention is given to certain important chapters of organic chemistry, for which an elementary knowledge of the subject is necessary. Frequent references are made to the original literature, and an attempt is made to acquaint the student with the classical researches of organic chemistry. Assistant Professor ORNDORFF.

23. Advanced Organic Chemistry. Laboratory work. The course in the preparation of organic compounds is here continued. These preparations being more difficult require more experience and skill on the part of the student. The original literature is consulted, and the student is finally required to repeat some extended and important piece of work and to compare his results with those published, before taking up original work in this field. Assistant Professor ORNDORFF. 24a. The Coal Tar Dyestuffs.. Lectures. Fall and Winter.

S., 12, Ch. L. R. 1.

The coal tar dyestuffs have become so important, from both a theoretical and a practical standpoint, as to justify their consideration in a separate course of lectures. The methods of making the dyestuffs, their properties, constitution and relations to each other are discussed, the treatment being scientific, rather than technical. Assistant Professor ORNDORFF.

24b. Stereochemistry. Lectures. Spring. S., 12., Ch. L. R. 7. The stereochemistry of the compounds of carbon and nitrogen form the subject of this course of lectures. The necessity for considering the space relations of the atoms in certain classes of physical isomers is shown and the close agreement of the facts and theory is brought out. Assistant Professor ORNDORFF.
