30 BULLETIN OF THE LABORATORIES 



During the school year of 1884-5 he pursued special studies in 

 Physics in the University of Berlin. He is a member of the American 

 Association for the Advancement of Science. Besides his publications 

 in the Bulletin of the Scientific Laboratories of Denison University, 

 given in the table of contents of that publication, he is the author of 

 " On the Refractive Index atid the Reflecting Poiver of Water and Alco- 

 hol for Electrical Waves" published in Annalen der Physik und Chemie. 

 and the Physical Review ; " Electrical Waves in Parallel Wires,'' in 

 the Proceedings of the A. A. A. S and the Electrical World; " Den- 

 son Univ. Laboratory Course in Electricity and J\Iagnetisni,'' and others. 



More than ten thousand dollars have recently been spent in equip- 

 ping the laboratories of Physics and Chemistry for efficient work. They 

 occupy fifteen rooms in Barney Memorial Hall. 



The Courses in Physics include eight and one-half terms of work 

 in Mechanics, Sound, Electricity, Heat, Light and Electrical Engineer- 

 ing. The work is largely laboratory work, and the laboratory is well 

 supplied with modern apparatus and reference books. Five large 

 power dynamos and motors, as many more small ones, ammeters, volt- 

 meters, spectrometers, photometers, polariscopes, etc. of recent con- 

 struction are available, and electrical current for light and power is fur- 

 nished by a storage battery capable of furnishing nine horsepower. A 

 shop, well furnished with power-driven machines for work in wood and 

 metal, furnishes opportunity for construction of apparatus for special 

 purposes. 



The course in Chemistry includes ten terms of work in (General 

 Chemistry, Qualitative Analysis, Organic Chemistry, Assaying, Sani- 

 tary Chemistry, Electro-Chemistry and Technological Chemistry. Six 

 analytical balances are provided for this work, also spectro- 

 scope, polariscope, storage battery for electrolytic work, three assay 

 furnaces for testing ores, Beckmann's apparatus for determining molec- 

 ular weights, Hempel's for gas analysis, etc. There are working 

 desks, well supplied with gas and water, for sixty students, and a con- 

 siderable collection of reference books. 



Instruction in Chemistry is given by daily lectures and recitations 

 during the spring to Freshman pursuing the course leading to the de- 

 gree of Bachelor of Arts. Remsen's Chemistry and the Laboratory 

 Manual of the same author are text-books used. Thorough experi- 

 mental illustration in the class room is sui)i)lemented by individual work 

 in the laboratory. Abundant apparatus and desk room, with water
