stains, etc., and be within easy reach of the operator. 

 These stains should be in glass bottles, with rubber teat 

 droppers fixed in them, and labelled. 



The microscope is conveniently placed in the middle of 

 the table, and, of course, accessible to the operator, or in 

 the best position for reflecting the light from the window, 

 a hanging gas-bracket, or an electric pendant. 



Other accessories found upon the table should be a test- 

 tube rack, cornet forceps, platinum needles, forceps, watch- 

 glass, various shaped and sized pipettes, spirit lamp, slide 

 trough for staining, distilled water flask and dropper, a 

 slab of plasticine, and one or two glass dishes with covers 

 to them. 



Another important addition is a laboratory sink. Any 

 ordinary sink -will answer if it is deep enough, and hot and 

 cold water should be laid on, with an additional small tap 

 under which is fixed a bracket shelf, and upon which the 

 glass slide to be washed is placed for the removal of 

 excess of stain, etc. 



Two or three rows of shelves should be fixed upon the 

 wall to carry bottles, etc. 



A pair of balances will be found most useful, and if put 

 in a cupboard with a glass door and fixed upon the wall at 

 a convenient height they occupy little room, and are within 

 easy access. Another strong shelf should be made to carry 

 an incubator and the two sterilizers (i.e., moist heat and 

 dry heat). Under each of these a gas-tap should be fixed* 

 a hole bored in the shelf, through which a rubber tube 

 passes, and leading to a Bunsen lamp, which is used for 

 the purpose of heating these apparatus. 



It is advisable to cover the surface of the shelf with 

 sheet metal to reduce the danger of fire. 



In addition one must have glass tubing, one or two glass 

 funnels, graduated measures, and glass flasks. The latter 

 need not be graduated, as they are somewhat expensive. 

 To standardize them, fill with water from a given graduated 

 measure, and with a grease pencil draw a ring round in
