V.
The figure on the bottom left-hand corner of Plate V. is a portion of the pretty Nitophyllum lacerátum, a plant belonging to the same family as the preceding one. The specimen here represented has a gathering of spores upon the frond, in which state the frond is said to be “in fruit.”
Fig. [27] represents a portion of the common sea-grass (Enteromorpha), so common on rocks and stones between the range of high and low water. On the left hand of the figure, and near the top, is a small piece of the same plant much more magnified, in order to show the form of its cells.

We now take leave of the vegetables for a time, and turn our attention to the animal kingdom.
On Plate [VI]. may be seen many beautiful examples of animal structures, most of them being taken from the insect tribes. We will begin with the antennæ, or horns, as they are popularly termed, of the insect.
