A New Botanical Laboratory. 91 



The windows are five feet wide and at just the height of 

 an ordinary table from the floor. They afford an abundance 

 of good light. Opposite each window are two tables, 

 4^ X 2^ feet, placed back to back. Accommodation is thus 

 afforded for ten students at one time, which answers all 

 present needs, though there is room for sixteen. 



Affixed to each pair of tables, at the outer end, is a' rack, 

 two shelves of which hold test tubes and specimen bottles, 

 while the two lower shelves hold narrow bottles containing 

 such reagents and stains as are in common use. For those 

 reagent which are required less frequently, the general 

 reagent stands 2, 2, are provided. Each table has a plain 

 wood top dressed with hot boiled linseed oil, while in the 

 centre of the working side there is a black working square, 

 18 X 24 inches. The furnishings provided each student 

 include a supply of needles, forceps, rods, dipping tubes, a 

 razor, various covered dishes and watch-glasses for prepara- 

 tions ; slides and covers, wash bottles holding distilled 

 water and alcohol ; drop bottles containing glycerine, car- 

 bolic acid and balsam: camera lucida, vegetation dishes, 

 Bunsen burner, and an albo-carbon drop light for illuminat- 

 ing purposes — an essential part of the outfit, on account of 

 the very early approach of darkness in winter. A row of 

 gas pipes, bearing T arms, extends the whole length of the 

 room. One end of each T — the outer — bears an ordinary 

 burner for illuminating purposes, while the other bears a 

 nozzle from which a rubber tube feeds the drop light of each 

 table. A wall bracket at each table supplies gas for the 

 Bunsen burner furnished to each student. 



At 9, the entire wall space between the doors is occupied 

 by a blackboard, which can be seen reaching from each 

 end of the room. At 5, a large sink is provided with two 

 taps, supplying water at a pressure of 120 pound; 4, is a 

 short bench for section cutting and other work of a similar 

 nature. It is provided with two microtome — one King and 

 one Becker — and a paraffine bath for imbedding ; 3 is a gen- 

 eral work bench, well supplied with gas, and also with a
