CHOICE AND USE OF APPARATUS 



obvious that a turntable is useless. Specimens 

 mounted in Canada Balsam do not need ringing, for 

 the Balsam is unaffected by air or the moisture 

 therein, when once it has set hard. 



Several firms supply prepared microscope slides, 

 and it is often useful to know where reliable prepara- 

 tions may be obtained. The slides supplied by Messrs 

 Flatters & Garnett Ltd., 409 Oxford Road, Man- 

 chester, are models of what well-made slides should 

 be. 



It always lends greater interest to the hobby if 

 objects are found and mounted by the microscopist 

 himself. By going out into the fields, by the pond- 

 side, or along the shore, in search of interesting 

 material for examination, much will be learned of 

 animal and plant habits which even the microscope 

 cannot reveal. Some of us, however, have neither 

 the opportunity to hunt for our specimens, nor the 

 time to mount them properly, and those of us who 

 are so situated will be glad to know where objects 

 may be obtained. 



Apparatus, useful for students of pond or sea-shore 

 life, may be obtained from Messrs Flatters & Garnett, 

 who always have a goodly stock of collecting jars, 

 nets, &c. From the same firm, also, may be obtained 

 stains and any of the limited number of chemicals 

 required by the microscopist. 



We have given a few simple directions for staining 

 in our chapter on Bacteria. In many cases it is 

 absolutely necessary to have recourse to stains in 

 order to see the structure of the objects we are
