OVULA IN SISYRINCHIUM AND CYNOGLOSRUM. IE 
of the second integument and nucleus, from the base of 
the cavity of the outer. Up to a latish period a vertical 
view shows no elongation of the outer coat upon the lower 
part of the second, see X. Fig. 7. It hence follows that the 
nucleus is the part first formed, and that it exists prior to 
any of the others. 
In this I have not succeeded in demonstrating the mem- 
branous nature of the embryonary sac, although I have 
examined it shortly after its appearance, it is rendered 
opaque by brown grumous matter: it is developed from the 
base of the cavity of the nucleus, but subsequently commu- 
nicates with the apex of this also. It is at this time very 
easily separable, even when the testa has commenced to 
come crustaceous : the sac is broken down entirely by 
pressure. 
At the time of expansion the ovula are madii: seated 
on stout funiculi, the raphe which runs through this, but has 
scarcely entered the ovula being uppermost or next the: 
axis. The two coats are distinct, the outer one being thick, 
the opening of the second projecting a little beyond that of 
the first. The nucleus is solid, with a central discoloured 
nucellus, which points out the site of the excavation which is 
to be.—Suddyah: July 2nd, 1836. 

Cynoglossum racemosum.—At the time of expansion the 
ovaria are completely inverted and the raphal side of the 
ovule is consequently turned outwards, the foramin inwards, 
and pointing to the base of the style. The stigmatic tissue 
is distinct and spreads out at the base of the style, forming 
a distinct communication with the interior of each ovary. 
The raphe is just commencing to enter the ovulum. The 
nucleus adheres intimately with the only coat, which is pro- 
longed at its apex into a longish neck; sometime after, this 
neck is in immediate connection with the stigmatic tissue, 
and about this time the nucleus is evidently excavated to- 
wards its centre. A little after, this excavation will be found 
increased and lined by a membrano-cellular embryonary sac, 
_at the apex of which the globula and rudiment of the
