Excerpt from The Canadian Entomologist, 1880, Vol. 12 The chief advantages of this process are: the ease with which it is done 5 the great convenience with which the specimens are preserved or transmitted through the post for identification or exchange 5 their greater durability, for they will stand much rougher handling than specimens pre served in the ordinary way 5 and, more important than all these, the fact that if you have only one specimen you can show both the upper and under sides at once, and also the membranous skeleton of the wings, which can thus be very easily examined and makes a beautiful object for the microscope 5 moreover. If you. Have only an imperfect specimen, it is possible to preserve a good likeness of it by filling in the wanting parts with water-colors. Further, it does not matter how old your specimens are 5 I have some prints which I have taken from butterflies collected in India more' than twenty years ago, which are quite as good as others printed on the same day that the insects were caught here.
