Or take a small capitu- lum of the sunflower. In addition to half of a sliced capitulum being displayed in one jar, in another can be suspended a mica sheet with dissections. These might consist of an entire and sectioned ligulate floret, a tubular floret in the latest bud stage, an- other in the expanded staminate stage, still an- other in the pistillate stage, and one in longitudinal section. They can all be neatly tied on by silk thread; but a preferable method would be to attach them with some transparent cement that would not alter in or be dissolved by alcohol. Such a cement is still a desideratum with me. Considerable ingenuity can likewise be displayed over fruits and seeds. Witness, for example, this preparation of the Thorn-.
