Many pollen- grains when in contact with moisture change their form en- tirely, a n d dif- ferent media will sometimes alter them still more. In contact with water the grains under consideration assume a spherical form, from which grow at ecjiiidistant points three processes or projections, which are usually the commencement of the pollen tube (Fig. 3, b). If this same pollen-grain be now placed in a 5 per cent, solution of formalin, it will in a short time assume the form of a wrinkled pea, the processes of which are nearly hidden (Fig. 3, c). The drawings b show the changes it undergoes when placed direct into honey, as would practically be the case when taken up with the nectar by the bee. b b shows a further development, and b c a still <&b-Section a mostly found in every drop of medium examined. {To be continued.).

I observed lately that the w ere consorting with the Entomo- logical Society, and so, I suppose, my thoughts were that way bent. The science is a very old one— indeed, I think, the very oldest, because "Adam gave names to all cattle, and to the fowl of the air, and to every beast of the ; We are not expressly told that h e gave names to all " in- sects '' : but why not? The task would be a hard one if we credit the fact that while all classes of ani- mals number only about 30,000, insects probably a
