tables and chairs conveniently proportioned and arranged 

 so that each pupil's place may be as well lighted as possi- 

 ble. If dissecting microscopes such as those recommended 

 on page 133 can be supplied by the institution, the work 

 will be much facilitated. Each institution should possess 

 at least one compound microscope with powers ranging 

 from 65 to 500 diameters, for demonstrating points un- 

 satisfactorily brought out under the lenses of the simple 

 microscope. However, most of the details called for in 

 the laboratory directions may be fairly satisfactorily demon- 

 strated under the lenses of a good dissecting microscope.

THE teacher should allow the laboratory work upon seeds 

 to proceed very slowly, taking care that the students make 

 their observations very carefully, finishing the work called 

 for by one paragraph before proceeding to that demanded 

 by the next. Very careful attention should be paid to the 

 manner in which the drawings of the different seeds and 

 their contents are made. They are very easy objects for 

 the most part; each detail can be plainly indicated and 

 labelled. If the student begins his work properly, the future 

 study will be made easier and better.
