1^04 Journal of Applied Microscopy 



Tools and material : Hammer, saw, brace, bits, twist drills, flat file, tri- 

 angular file, round file, screw driver, pliers, sand paper, nails, tacks, monkey- 

 wrench, fine wire, screws, pins, thread, twine, sealing wax, wire netting, etc. 



A work shop containing a suitable work bench will repay its cost yearly. 



Carrying-trays, say 30 x 10 inches or 24 x 18 inches, for moving bottles, or 

 for taking material to the basement to avoid freezing, should be made of thin 

 wood and should have handles at the ends. 



Window trays for holding plant boxes may be made of zinc, or wood lined 

 with zinc. They should fit the window sills, and should be a trifle wider than 

 the length of a chalk box. Three inches is a convenient depth, 



INDIVIDUAL EQUIPMENT. 



The school should provide each pupil with the following articles : 



A Dissecting Set. — These cost less than one dollar per set, and will include, 

 in a case, two mounted needles, one or two pairs of forceps, one scalpel, and one 

 pair of scissors. The small lens sometimes included should be omitted. 



A Dissecting Microscope. — These are so much more effective than the ordi- 

 nary magnifying glasses, that the extra cost is more than compensated for. The 

 Barnes dissecting microscope (Bausch & Lomb), with a doublet lens No. 2 (10 

 diameters), is a useful form. Other dealers have similar instruments. Cheap 

 instruments with poor lenses should be avoided. An extra lens of higher power 

 may be added when finances permit. Pupils should be encouraged, but not 

 required, to purchase a pocket magnifier. 



A Dissecting Pan {for zoology work) — Cheap substitutes may be made by the 

 local tinner. Square glass candy trays are cheap and durable. Cork or wax 

 bottoms are necessary. 



The pupil should provide himself with the following : 



A Note Book. — One with removable leaves is recommended ; a portion of 

 these should be drawing paper. 



A Drawing /'t7/<r//.— Either HHH or HHHH quality. 



A Chalk Box. — These are to be used for germinating seeds. Pine sawdust 

 is^better than sand. 



APPARATUS. 



The following equipment will enable the school to perform nearly all the 

 experimental work in botany, zoology, and physiology given in any of the texts 

 in common use. The quantities specified are such as experience has shown to 

 be desirable for a class of twelve pupils. Pieces used but for a single experi- 

 ment have been omitted. 



1 blast lamp. 1 nest beakers, assorted 1-4. 



1 doz. dissecting microscopes (10 1 doz. alcohol lamps, 4 oz. 



diam.). 1 doz. dissecting sets, including needles, 

 1 doz. dissecting pans, paraffin bottoms. forceps, scalpel, scissors. 



1 set cork borers (six). 1 cork press. 



1 doz. corks, large flat, 2^ in. diam. 1 gross assorted corks. 



3 graduates, 100 c.c, cylindrical, 2 doz. rubber stoppers, single and 

 1 set weights, 2 kilo to 5 grams. double perforated.
