i. A grain of Cocculus Indicus, n. s.

2. A diagram of the seed constructed from dissections; a, the outer

skin, composed of irregularly-shaped cells full of dark brown colouring matter in three or four layers overlying; b, elongated branching fibrous cells, anastomosing amongst the elongated fibres (<r) and the cylindrically formed wood cells at g: these form the hard or woody portion of the grain, in which are seen at intervals the spiral vessels (s v); d, layers of double-pointed fibres with thickened walls and lateral channels; <?, albumen of the seed (cellular), containing much starch;

f, cells of albumen separated to show their pores.

3. A grain of Paradise, magnified 8 diameters.

4. A diagram of the seed: a, the elongated wavy cells of the outer

skin, overlying b, the woody tissue, amongst which are numerous oil receptacles, 0:the branched fibres are seen anastomosing amongst these, e; c, the thin tough-walled cells of the albumen, containing abundance of minute starch granules.

5. Oil globules from the large cysts at b.

6. A grain of Datura Stramonium, magnified 2 diameters.

7. A horizontal diagram of the seed: a, long thin-walled cells of

outer seed coat; b, layer of thick-walled coloured cells underlying it; c, a layer of long delicate cells underlying these, and overlying a layer of same form at a right angle to these; e, cyst containing dark brown colouring matter ;/, a layer of long delicate cells with thin walls, and another of short cells with thick walls firmly attached to albumen (g), composed of very thick-walled cells laden with minute starch granules;

g, cells of albumen very highly magnified.
