In all the other insects we find them much as in the bees, with the separate parts varying greatly in form, to agree with the habits and character of their posses- sors. No wonder DeGeer and Fabricius detected these varying forms as strongly indicative of the nature of the insect, and no wonder that by their use they were so successful in forming a natural classification. If, as seems certain, the " Doctrine of Natural Selection " is well founded, then a change in habit is the precursor of a Fig. Microscope Mounted for Dissecting.—Original. change in structure. But what organs are so intimately related to the habits of animals, as the mouth and other organs that have to do with food-taking and food-getting ? Every bee-keeper will receive great benefit by dissecting these parts and studying their form and relations for himself. By getting his children interested in the same, he will have conferred upon them one of the rarest of blessings. To dissect these parts, first remove the head and carefully pin it to a cork, passing the pin through, well back between the eyes. Now separate the parts by two needle-points, made.
