GEOMETRICAL (Cyd.)~- Geometrical method of the. an- tients. It is to be obferved that the antients eftablifhed the higher parts of their geometry on the fame principles as the ele- ments of that fcience, by demonft rations of the fame kind j and that they feem to have been careful not to fuppofe any thing done, till by a previous problem they had fhewn how it was to be performed. Far lefs did they fuppofe any thing to be done, that cannot be conceived, as a line or feries to be actually continued to infinity, or a magnitude to be diminifh- ed till it become infinitely lefs than what it was. The ele- ments into which they refolved magnitudes were finite, and fuch as might be conceived to be real. Unbounded liber- ties have been introduced of late, by which geometry, which ought to be perfectly clear, is filled with myfleries. See Mac Lauren's Fluxions. Introd. pag. 39. feq.

The common wild forts of this plant, and thofe alfo which are brought to the curious from the colder climates are hardy enough, and require little care ; but the African fpeeies, and the others frqm hot countries, which make fo very beauti- ful a figure in our green houfes, require great care in their culture and propagation.

Thefe are to be raifed by planting cuttings of them in any of the fummer months in beds of light rich earth, and care- fully fhading them from the fun, and giving them frequent, but gentle waterings, till they are well rooted. The mats with which thefe beds are covered are to be taken off" in gentle mowers, and always in the hot weather at. nights, that the plants may have the benefit of the dew. They mould remain about two months in this bed, by which time they will have taken root. Some pots of about feven inches wide are then to be filled with light earth, and the plants are to be carefully taken up with as much as ptiflible 01 their own earth about them, and planted feverally in the middle of thefe pots ; when they are to be fet in a fhady place, and watered at times till they have taken root. When they are well root- ed they fhould be fet in a more expofed place to harden them, and mould ffand out till the middle of October; but when the mornings begin, to grow frofty they muff be removed into the green-houfe, and then placed as near the windows as poflible, and the windows fhould be opened upon them till the weather is very cold. During the winter they muft be frequently watered a little at a time, and their dead leaves fhould be pulled off. They mult not fland under the fhade of other plants, nor need any artificial heat. Some raife them alfo from feeds, which mult be carefully preferved and fown on fine light earth, and when they come up be tranfplanted into other beds of rich earth, with dung at the bottom. They muft be fet here at about fix inches afunder, and in July they fhould be tranfplanted into pots, and from that time managed exactly as thofe raifed by cuttings. Miller's Gard. DicT

Geranium ftands recommended as one of the greateft vulnera- ries and abftergents of the vegetable world ; and is highly extolled for its power of ftopping profluvia of the menfes, and haemorrhages of all kinds. Experience confirms the truth of this, efpecially among the poor people in the country j and it were to be wifhed that the plant could be brought into more efteem in the fhops, where at prefent it is disre- garded. GERANOS, Tsfanjc, in antiquity, a remarkable dance perform- ed in the feftival called delia. See Delia. GERARDIA, in botany, the name of a genus of plants the characters of which are thefe. The perianthium is compofed of one leaf divided into five fegments, and remains after the flower is fallen. The flower is of the labiated kind, and compofed only of one leaf. The tube is longer than the cup, and of a cyhndric figure. The upper lip is erect, plain broad, obtufe and emarginated. The lower lip is bent back- wards, and divided into three fegments. The two fide ones are long and emarginated, and the middle one fhorter and bifid. The ftamina are four filaments fomewhat fhorter than the flower, and two of thefe are a little fhorter than the other two. The anthers are fmall. The gcrmen of the piftil is fmall and oval. The ftyle is fimple and fhort, and the ftigma is obtufe. The fruit is an oval bivalve capfule, containing two cells, and opening at the bottom ; when ripe the feeds are fingle and oval. Linnai Gen.
