Annotation

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. When the time comes for it to make the Great Change, to transform itself from a gluttonous worm into a winged moth, to cease its gross existence as a creeping thing and to enter into an aerial life, to sip honey and to make love, it requires an envelope for hiding, for a dark and secret place, according to the command of Nature. From certain glands at the back of its head it ejects two minute threads of a viscous liquid which become coated with another secretion flowing from two other convenient glands, and these two little streams are thus cemented to a double strand.
