Page 306 - To-day I saw the dragon-fly Come from the wells where he did lie. " An inner impulse rent the veil Of his old husk : from head to tail Came out clear plates of sapphire mail. " He dried his wings: like gauze they grew: Thro' crofts and pastures wet with dew A living flash of light he flew.
Page 362 - ... immediately," according to Mr. FW Putnam,* "collects a small amount of pollen mixed with honey, and in this deposits from seven to fourteen eggs, gradually adding to the pollen mass until the first brood is hatched. She does not wait, however, for one brood to be hatched before laying the eggs of another, but, as soon as food enough has been collected, she lays the eggs for a second. The eggs...
Page 52 - Take out a leaf and put it into a vessel of water ; rub it between the fingers under the water. If the epidermis and parenchyma separate easily, the rest of the leaves may be removed from the solution, and treated in the same way ; but if not, then the boiling must be continued for some time longer. To bleach the skeletons, mix about a drachm of chloride of lime with a pint of water, adding sufficient acetic acid to liberate the chlorine. Steep the leaves in this till they are whitened (about 10...

Page 2 - ... the various departments of Natural History invites the establishment of a journal which shall popularize the best results of scientific study, and thus serve as a medium between the teacher and the student, or, more properly, between the older and the younger student of nature The value of the magazine will depend more on its power to awaken the absorbing interest invariably excited by the contemplation of nature, and of illustrating the wisdom and goodness of the Creator, than on any adornment...
Page 449 - weightier matters of the law," it is also true that in no other way could the material laws of the universe be thoroughly investigated than by making them the subjects of an absorbed and undivided attention.
