important is a. tool-and-gas table equipped with bunsen and 

 other burners, and the ordinary tools as described in the next 

 chapter. This should be 3 feet high, and the space beneath it 

 used one half for drawers and the other for cupboards. So 

 much apparatus is needed in this course that ample storage 

 room must be provided, and hence the long case shown on the 

 plan, with numerous drawers beneath, and glass-fronted cases 

 above, will be none too large. Separate cases should be pro- 

 vided, too, for books and for chemicals ; and radiators, or, better, 

 lines of heating-pipe along the walls beneath the windows, are 

 necessary. A case for the balances may well stand on one of 

 the apparatus tables. The windows should be broad and tall, 

 and should be opposite the student's tables and the tool-table, 

 while one half of the partition between laboratory and green- 

 house may best be of glass. Such seems to me a profitable 

 general arrangement, though a far simpler one allows of 

 extremely good work. 



4. APPARATUS AND MATERIALS. 



A list of the appliances and materials needful for a practi- 

 cum in physiology will now be given. It is not always easy 

 to determine whether certain given pieces shall be included or 

 excluded, since the scale of equipment is a sliding one which 

 can be considerably expanded or contracted according to 

 circumstances; but as a standard I shall take the equipment 

 actually used by my own class of twelve students in the present 

 (1899-1900) year. This may be taken to represent an optimum 

 of equipment for such a course, but some of the articles could 

 be omitted without serious detriment to the work. Although 

 at first glance the list may appear formidable in length, it is 

 really hardly longer than would be a list of the equipment of a 

 good anatomical course with its microscopes, microtomes, 

 paraffine baths, etc. Moreover, it is not needful to procure all 

 of the appliances at once, but they may be added a few at a
