2. Dissecting dishes. 



A small pie-dish 6 or 8 inches in length, and an ordinaiy 

 salve-pot will meet all requirements. They should be 

 half filled with a mixture of paraffin and lamp-black, put 

 in hot, and weighted down with a piece of sheet lead. 



3. Injecting apparatus. 



Two or three ^-oz. medicine-droppers, with their points 

 drawn out to varying degrees of fineness. 



A 1-oz. syringe, preferably of metal, for histological 

 work. 



4. A compound microscope, preferably with a short body ; 

 fitted with low power ( i inch) and high power (Jth inch) 

 objectives. A shallow eye-piece of low magnifying power 

 will suffice, but a higher one may conveniently be to 

 hand. 



5. A hand-lens : preferably of the pocket or watchmaker's 

 type. 



A simple dissecting microscope may conveniently be 

 added. 



6. Sundries. 



Drawing material. Unlined paper ; pencils H and 

 HB, and a box of moist-colours. Paints may be em- 

 ployed in preference to chalks, and it is advisable to 

 use corresponding colours in representing corresponding 

 organs of different organisms, or corresponding parts of 

 organs themselves. 



In drawing, accurate representation in outline should 

 be aimed at, and it will generally suffice to colour in light 

 flat washes. 



Microscopic slides and cover-slips. 



Of the former, \ a g ross ? with rough or ground edges at 



will. 



Of the latter, 2 oz., preferably square thin. 



Glass dipping-tubes of various calibres and lengths ; 



two or three to be drawn out to a point
