HOW TO SELECT AND STUDY FRESH SPECIMENS. 23 



In describing the colors of soft parts, I would advise you to 

 purchase the following 1 Windsor & Newton tube colors (oil) 

 and use them as standards for reference : Ivory black, Vandyke 

 brown, burnt limber, burnt sienna, raw sienna, Naples yellow, 

 Indian yellow, chrome yellow, Indian red, vermilion, purple 

 lake, cobalt blue, and indigo. 



LABELLING. For scientific- purposes, a specimen without a 

 label is not quite so good as no specimen. It takes up room, 

 and is useless. The most important record to make on a label 

 is the name of the locality in which it was taken. Next in im- 

 portance is the date of its capture. You may leave off every- 

 thing else if you really must, for as to its name the specimen 

 can speak for itself. But it is by all means desirable that the 

 label should give the name, locality, date, sex, and some meas- 

 urements. I need not mention " name of the collector," for the 

 collector can always be trusted to look out for that without 

 advice from anybody, even under the most discouraging cir- 

 cumstances.
