LABELLING AND MOUNTING SPECIMENS.

fastened to the object holding the specimen. In the case of 

 a bird stand or wooden tablet, this is effected by perforating 

 the end c and then using a tack. When applied to a botde, 

 copper wire is used. The end c is folded around the wire 

 and the wire then placed around the neck of the bottle and 

 the ends twisted tightly. The advantages of this method are 

 many ; the label is firmly held and at the same time can be 

 readily removed by loosening the 

 folds with a knife. All original labels 

 can be safely preserved out of sight 

 by placing between the public label 

 and the tin strip. The labels are 

 also kept flat and by bending the tin 

 at b can be readily disposed so as to 

 be more easily read when on a high 

 or low shelf. 



In the case of alcoholic speci- 

 mens a label should always be kept 

 in the bottle, as well as one on the 

 outside. This label should be 

 written with a soft lead pencil, or 

 with India ink dissolved in acetic 

 acid (never with common ink) on parchment or very strong 

 paper. This label, which is intended only for the student 

 and curator, should contain every item of information re- 

 garding the specimens. 



Insect labels should be kept on the pin and should be small. 

 It is usual in arranging insects to place them in rdws and 

 then in the farther left hand corner is placed the family label.
