The different forts of this plant make beautiful ornaments for cliimnies,and other places, being very tail, very much branched, and full of large and beautiful flowers, which retain their beauty a long time.
They are propagated by fowing their feeds in March, in a bed of light and undung'd foil, or by parting the roots; but the latter method being the more expeditious, is moll practifed . Almoft every flip, taken from the roots in September, and in March, will thrive ; but the plants raifed from feeds are ken to produce the fineft flowers : they are very tedious, however, this way, being three or four years before they flower. They

'mould, therefore, be tranfplanted the September after their" fowing into nurfery-beds, which fhould be of a light foil and not wet ; they fhould be fet here at fix inches fquare, and in frofry weather, the whole beds fhould be covered with mats, which will greatly ftrengthen the roots. In the September of the third year, they fhould be removed into pots, and fheltcred, during the fevere weather, in glafs frames; or elfe in wet weather, the pots muft be turned ftdeways ; and in very cold, they muft he fet^ under a warm wall, and covered with haulm, and furrounded with a little dung on the outfides of the pots, to preferve the roots from the frofrs. Thefe plants will often fucceed without this care, but with it they produce their flowers in fuch beauty and plentv, as amply to reward it, Miller's Gard. Diet

CAMPHOR (CycL)—lt has been difputcd to what fpecies of vegetable juices camphor properly belongs ? fome will have it a gum, others a refm, others a volatile fait. Phil. Tranf. N° 3^9- P- 3 22 -.
But camphor is we'd known to be a vegetable production, and much has been written of it by the chemifts, yet we do not feem to have any fatisfactory account of it, either as to the manner in which it is collected in the Indies, or as to what it truly is; and while we readily acknowledge it a vegetable production, yet it is odd, that we cannot produce any o.her fubject perfectly like it, either from the animal, vegetable, or mineral kingdoms.
It is evident, that it is neither a fait nor a gum, fmce it is not folublein water; nor is it a refin, fince it does not yield by diftillation either a phlegm or oil, or an acid fpirit, as all re- finsdo; much lefs does it leave a caput mortuum like thofe bodies. It totally vanifhes and evaporates in the open air ; in hot water, it firft runs and then evaporates, and in fpirit of wine, or fpirit of nitre, it wholly diffolves. It is no oil, be- cause it is not unctuous to the touch, but is a firm, dry, cry- flalliz'd matter; in its evaporation in the air, it leaves no re- mainder; and in clofe veffels over the fire, it rifes entire with- out diftillation, and appears at the top of the vefTel in a dry form. It leaves no caput mortuum, is fubject to no feparation of parts, and takes no empireumatic fmell ; in mixing with concentrated fpirit of nitre, it makes no ebullition, but pla- cidly refolves into a fort of oil. This is extremely different from the effect of all vegetable oils, which are known to ef- fervefce violently with this acid, and fome even to take fire, and are finally converted by it into a dry refin. Camphor is therefore an inflammable fubftance, fui generis, an artificial, fublimated, dry, white, pellucid, and cryftallized body, acrid to the tafte, of an aromatic fmell, extremely fragrant, brittle, and eafily evaporable by fire, or in a warm air. When broken, it appears bright, fmooth, and faponaceous, but not unctuous to the touch; it conftfts of a copious inflammable principle, a fmall portion of water, and yet lefs of a very fine and fubtile earth, mixt intimately together. Act Eruditor, 1727. p. 524. The common ways of keeping it from evaporation, are by burying it in linfeed, millet, pepper, or the like, but the ra- tional way is, by keeping it from the external air ; this is beff. done by wraping it up in a paper or bladder, and putting it then into a leaden box, or an earthen, or glafs vefTel fet in a cool place. Or it may be preferved in large quantities, only by papering it up carefully, and putting it in wooden veffels in a cellar. Notwithftanding that it is a body fo nicely and intimately combined, in its own texture, yet it is ready at all times for medicinal ufe; and as it is not eafy to give it any preparation, fo it needs none. In its natural ftate, it readily mixes with all oils and inflammable fpirits, and this without fear of evaporation ; it has no. change of colour in folution with fpirit of nitre, but when diflblved with oil of vitriol, it becomes brown, and finally, red; and if water .be added to either of thefe folutions, the camphor is precipitated in its pro- per and folid form ; it may, however, be abfolutely difFolved, by long maceration and frequent drawing over by the retort, with either of thefe menftruums.
The two medicinal preparations of campho^, m ufe now in the fhops, are the folution of it in wine and in oil; the one called camphorated fpirit of wine, the other, oil of camphor

Th
