them ; and, as the autumn comes on, that the heat de- 
creafes, they may be removed into places more expofed 
to the fun, where they may remain until October before 
they need_ be houfed. Towards Chrifhnas, if the roots 
are in good health, the firft fort will begin to flower, and 
continue producing frefli Rowers till the middle of Fe¬ 
bruary, and thefe will be fucceeded by the Perfian fort', 
which continue till May : but, if you intend to have any 
feeds, you mull let the pots be placed fo as to receive a 
great (hare of frefli air; for, if their flowers are drawn 
up in the houfe, they feldom produce any feeds. Thefe 
feeds are ripe about July, when they fhould be immedi¬ 
ately {’own in pots or cafes of good light undunged earth, 
which fhould be fheltered in winter under a frame, and 
expofed in fumvner in the fame manner as is directed for 
the older roots, obferving to remove them into pots at 
a wider diftance when they are two years old, and fo 
from time to time, as their roots irjereafe in bulk, you 
mud give them more room ; and in about four or five 
years they will begin to flower, when each root fhould 
have a feparate fmall pot, and, when it is grown large, 
a larger. When the firft fort is planted in an open bor¬ 
der, common hot-bed frames fhould be placed over it in 
winter, to protect it from fro ft. Thus managed, it will 
produce more and fairer flowers than when planted in a 
pot, and good feeds may be expected from it. Perfons 
who are curious in flowers fhould have a border framed 
over, on purpofe for thefe, the Guernfey and Belladonna 
lilies, with other curious bulbous roots.

not opening. Seed: (ingle, kidney-form.— FJfential Cha¬ 
racter. Calyx, four-parted, fpreading, with a fliort tur¬ 
binate tube ; corolla, none ; filaments inferted into the 
neck of the calyx; flyle flexuofe; legume roundifh, 
winged, one-feeded. 
Species, i. Cyclas fpicata, or fpiked cyclas : leaves pin¬ 
nate. The trunk of this tree is from thirty to forty feet 
liigh, and a foot and a half in diameter. The bark is 
grey, and fmooth ; the wood Whitifh. It lias fcveral large 
boughs at top, fpreading in all directions. Flowers in 
long fpikes, axillary, and terminating, on fliort pedicels. 
Native-of the great forefts of Guiana; flowering there 
in November, and fruiting in January. The Caribee 
name is apalatoua. 
2. Cyclas aromatica, or aromatic cyclas: Jeavesovate. 
The trunk of this tree is from forty to fifty feet high, 
and more, and about two feet in diameter. Native of the 
great forefts of Guiana, in marfliy places; it flowers there 
in December, and bears fruit in May. The Caribee name

CYGLI'DIUM, f. in zoology, a genus of infuforia 
or worms; invifible to the naked eye, very Ample, pel¬ 
lucid, flat, orbicular or oval. Thefe rank among the 
animalcuhe, and are obferved chiefly in vegetable infu-- 
fions. Seven fpecies have been afeertained,- one of 
which, the pediculus, is found on the arms of the hydra 
fufea, or frefli water polype, and is an inhabitant of Eng¬ 
land. The cyclidium bulla is among the fmalieft of this 
tribe ; and is alfo found in England, in infufions of hay. 
It is a very pellucid orbicular white animalculum, the 
edges a little darker than the reft. By the affiftance of 
the compound microfcopfc, fome globular inteftines of a 
very cryftalline appearance are juft perceptible in the 
center of the animal. The cyclidium glaucoma, is 
found in water that has been l;ept fbgnant about fix 
months. It has a pellucid oval body,"with both ends 
plain, or an oval membrane, with a diftinSt well-defined 
edge ; the inteftines are fo very tranfparent that they 
can fcarcely be difeerned when empty, even by the mod 
powerful magnifier: when full, they are of a green co¬ 
lour, and there are dark globules difcoverable in the 
middle. In plenty of water it moves fwiftly in a circu¬ 
lar and diagonal direction ; whenever it moves fiowly it 
fee ms to be taking in water, the inteftines are then more 
vilrble, and in a violent commotion. Two of the fmaller 
ones may often be perceived cohering to each other, and 
drawing one another by turns ; nor are they feparated by 
death, for they remain united even when the water is 
evaporated. Thole who are not .familiar with thefe 
kinds of curious obfervations, may eafily miftake the 
lhade in a (ingle one for a junction of two, or the .junc¬ 
tion of two for a copulation, for they generate by .divi- 
(ion. Some fpecies of thefe, magnified, may be feen in

C Y'CLOID, J. [from y.vy.XoBi^r,c, of v-vyJKoc, a circle, 
and e i 5 o?, lhape.] A geometrical curve, of which the 
•genefis may be conceived by imagining a nail in the cir¬ 
cumference of a wheel : the line which the nail deferibes 
in the air, while the wheel revolves in a right line, is 
the cycloid. This is the curve on which the doftrine of 
pendulums, and time-meafuring inftruments, in a great 
meafure depends. Mr. Huygens demonftrated, that from 
whatever point or height, a heavy body, olcillating on a 
fixed center, begins to defeend, while it continues to 
move in a cycloid, the time of its falls or ofcillations will 
be equal to each other. It is likewile demonftrable, that 
it is the curve of the quickeft defeent, i.e. a body falling 
in it, from any given point above, to another not exactly 
under it, will come to this point in a lefs time than in 
any other curve palling through thole two points.
