We have now, in the last place, to notice the chiefpoints of interest to the Microscopist, which are furnishedby mature Seeds. Many of the smaller kinds of these bodiesare very curious, and some are very beautiful, objects, whenlooked-at in their natural state, under a low magnifying the seed of the Poppi/ (Fig. 190, a) presents a regular Fig.
