base of grain; (ff) lines representing the position of the paleae, 
which are seen in their natural condition in fig. 3; (g) the pe- 
dicel or receptacle to which the grain is attached. 
Fig. 2 shows the ripe grain of rye, twice magnified; (a) 
embryo; (b) crown of hairs; (c c) shrivelled stigmas; (d) albu- 
men, composing body of the grain; (g) pedicel. 
Fig. 3 shows ripe grain in its natural position between the 
paleas (ff). 
Fig. 4 is intended to give a representation of the com- 
mencement of the formation of the ergot; but an accurate idea 
cannot be well given, on account of the minuteness of the par- 
ticles and filaments composing the fungus: (a) is the ovary of 
the grain overrun with the fungus, which completely hides it 
from the view; (b) shows the fungus has cemented the anthers 
and the stigmas together; (ee) the two scales at its base, sepa- 
rated from each other to show the extent of the fungus, which 
stops generally at the receptacle (g), all these parts being twice 
or three times larger than natural. 
Fig. 5. The ergot about half grown as it begins to show it- 
self between the paleae; (a) ergot beginning to lose most of its 
filaments and sporidia, and beginning to appear purplish; 
(ee) scales at its base, that have been spread open; (g) recep- 
cle; (h) remains of hairy crown and stigmas. 
Fig. 6. Matured ergot, exhibiting the furrow and several cracks 
and fissures, and retaining (ee) the two scales, and (g) recepta- 
cle, not altered; (h) remains of stigmas and hairy crown, still 
adhering. This and the preceding figure are twice the natural 
size also. 
Fig. 7. A portion of a transverse section, so thin as to be trans- 
parent, magnified 700 times, showing the irregular, cellular 
structure enclosing minute fatty particles. 
Fig. 8 represents some of the sporidia, magnified 1000 
times, and which contain different numbers of green granules; 
the first, however, having none. Phoebus' figure of these is 
precisely similar; but Philippar's very imperfect. 
Fig. 9 is their germination, by emitting tubes containing 
granules similar to those of the sporidium producing them.
