Journal of Applied Microscopy 



on " Metameric Segmentation," at the originally planned hour, 4 p. m., but the 

 three lectures by Dr. G. N. Calkins on the " Protozoa '" and three by Prof. G. H. 

 Parker on the " Sense Organs of the Crustacea " were given in the evening at 

 the general lecture hall. 



The laboratory work of the day was divided into two periods of two hours 

 each, the first from 10 a. m. to 12 m., the second from 2 to 4 p. m. During 

 these periods it was the duty of three instructors to be in the laboratory for the 

 purpose of distributing material to the students and to answer such questions as 

 they might be asked concerning the work of the day. Besides these regular 

 working hours the laboratory was open at all times to the students and many of 

 them took the opportunity to carry further the work begun in the course or to 

 work along lines in which they were especially interested. The work in the lab- 

 oratory consisted chiefly in gross dissections and microscopical studies but some

work was given in killing, staining and mounting small animals and in mounting 

 and interpreting serial sections. Each student furnished his own dissecting 

 instruments, drawing materials and microscope. In many cases the micro- 

 scopes were owned by the students, but in others they were rented for the course 

 from the Bausch ^r Lomb agency. For a rental of five dollars a student was 

 provided with a B.B. stand furnished with an Abbe Condenser, two eyepieces 

 and two objectives. 



Students were advised to make accurate drawings of what they saw, and in 

 case the work was to be substituted in their college course such drawings were 

 required. 



The table which follows will give a better idea of the actual work done in 

 the course and the manner of conducting it, than could be gotten from a lengthy 

 description.
