pulp is wholly compofed of bladers, in which many of 
thofe threads whereof the bladders are wove, are fo loofe, 
as to be eafily drawn out to a confiderable length, and 
are very vifible when applied to the microfcope. 
The feed cafe abed, of yellow henbane, fig. 434. 
opens on both Tides, from its top at a, grows a Item, 
which diminilhes as the cafe fwells, and at laft falls off". 
On the fides of the cafe run two oppofite*vafcular fibres, 
and as the cafe gradually increafes, it as gradually fepa- 
rates on both fides in the tract of the aforefaid fibres as 
at b. The cafe is lined with a fmooth thin {kin, in 
whofe center is a great parenchymos bofs c, being the 
bed of the feeds which lie all over as in a Itrawberry; 
throughout this bed the veffels d, for the generation and 
nourilhment of the feed, are diftributed, as may be feen 
in the tranfverfe fedtion thereof at d, in which a very 
fmall fibre, {hooting from the diredt fibres obliquely into 
each feed, is plainly vifible. 
The feed cafe of a tulip, whereof a, reprefents the cafe 
intire, b is a tranfverfe fedtion of it, and c the cafe fplit 
down. Fig. 345. it opens on three fides, from the midft 
of each proceeds a partition, all meeting in the center 
of the cafe, and making fix divifions for the feed. The 
veflels are curioufly difpofed after they rife above the 
ftalk, being at firft divided into three principal branches, 
running along the three angles of the cafe, from which 
divers lefler branches tend horizontally, and meet at the 
middle of each fide; whence they proceed through the 
breadth of each partition to their edges, in the center of 
the cafe, where they are again diftributed into very fine 
and ihort threads, whereon the feeds hang. 
The feed of anagallis or pimpernel, fig. 436, is a little 
globe opening horizontally into two hemifpheres, the
