aperture to look through ; and an opening may alfo be 
made in the fide of the box, for the convenience of draw¬ 
ing. This fort of camera is eafiiy changed into a fliow- 
box for viewing prints, &c. placing the print at the bottom 
of the box, with its upper part inwards, where it is en¬ 
lightened through the front, left open for this purpofe, 
either by day or candle light; and the print may be view¬ 
ed through the aperture in H I. A variety of contrivan¬ 
ces for this purpofe may be feen defcribed in Harris’s Op¬ 
tics,. b.ii. feel. 4. 
Mr. Storer has got a patent for a camera of this kind, 
which he calls a delineator; being formed of two double 
convex lenfes and a plane mirror, fitted into a proper box. 
One lens is placed clofe to the mirror, making with it an 
angle of 45° ; the other being placed at right angles to the 
former, and fixed in a moveable tube. If the moveable 
lens be direfled towards the object, which is to be viewed 
or copied, and moved nearer to or farther from the mirror, 
till the image is didindly formed on a greyed glafs, laid 
upon that fnrface of the upper lens which is next the eye, 
it will be found more fliarp and vivid than thofe formed 
in tive common inftruments; becaufe the image is taken 
up fo near the upper lens. And, by increafing the diame¬ 
ter and curvature of the lenfes, the effect will be much 
heightened. See Dioptrics.

C AMERA'RI A,f [fo named by Plunder from Joa¬ 
chim Camerarius, a phyfician and botanid of Nuremberg.] 
In botany, a genus of the clafs pentandria, order mono- 
gynia, natural order contortae. The generic characters 
are—Calyx : perianthium five-cleft, acute, converging, 
very fmall. Corolla: monopetalous, funnel-form; tube 
cylindric, long, bellied out at the bafe and tip ; border 
five-parted, flat; divifions lanceolate, oblique. Stamina: 
filaments five, very fmall, from the middle of the tube ; 
anthene converging. Prdillum: germs two, with lateral 
appendages ; flyles hardly any ; digmas obfeure. Peri- 
carpium: follicles two, horizontally reflected, oblong, 
obtufe at both ends, and fending forth a lobe each way 
near the fides of the bafe, one-celled, one-valved. Seeds: 
numerous, ovate, inferred on the larger ovate membrane 
at the bafe, imbricate.— F.Jfential Charader. Contorted;

follicles two, horizontal'; feeds inferted into-their proper 
membrane. 
Species, t. Cameraria latifolia, or badard nianganeel : 
leaves ovate, acute at both ends, tranverfely flriated. This 
is a tall elegant tree, about thirty feet in height, abound¬ 
ing vvith an acrid milky juice ; leaves fomewhat refemblirig 
thofe of myrtle ; flowers white. It was fent to Mr. Mil¬ 
ler from the Havannah by Dr. Koufioun. The flowers 
appear in Augtid, but never produce any feeds in England. 
2. Cameraria angufiifolia : leaves linear. S{em irregu. 
lat ly brandling, (lirubby. Flower and fruit much fmaller 
than in the foregoing fpecies, as is the whole plant. It 
grows about eight feet high abounds with an acrid milky 
juice, like the other fort; and grows naturally in Jamaica. 
Propagation and Culture. Thefe plants are propagated 
by feeds, which mud be procured from the places of°their 
growth. They may alfo be increafed by cuttings planted" 
in a hot-bed during the fuinmer month's. They mult have 
a bark-(love, for they are very tender ; but in warm wea¬ 
ther they nmft have plenty of air. See Montia. 
C AMERA'RIUS (Joachim), a learned German, born 
at Bamberg in 1500, and educated at Leipfic. Here he 
loon diftinguilhed liimfelf by his uncommon abilities; and 
his more uncommon application to letters foo.n made him 
known 10 all the eminent men of his time. In 1534 he 
was offered the place of fecretary to the fenate of Nurem¬ 
berg ; but, preferring the eafe and freedom of a ftudious 
life to all advantages of a pecuniary nature, he refufed it. 
Tv.o years after Ulric prince of Wirtemberg fent him to 
Tubingen, to reftore the difeipline and credit of that uni- 
verlity; and, when.he had been there about five years, 
Henry duke of Saxony, and afterwards Maurice his fon, 
invited him to Leipfic, whither he went, to direft and af- 
iifl in founding that univerfity. In 1556 he accompanied 
Melandhon to the diet of Nuremberg ; and attended him 
the year after to that of Ratifbon. After [pending a life 
of letters and happinefs, he died, full of years and ho¬ 
nour, at Leipfic, April 17, 1575. His labours in the lite¬ 
rary republic were prodigious. He wrote a vail number 
of books; and, which in thofe days was no fmall fervice, 
tranflated as many. Greek was but little uhderdood ; fo 
that, to facilitate the learning of that language, he tranfla¬ 
ted feveral authors of antiquity : Herodotus, Demofthe- 
nes, Xenophon, Euclid, Homer, Theocritus, Sophocles,. 
Lucian, Theodoret, Nicephorus, &c. Melchior-Adam 
fays, that “he ftudied evermore, within doors and with¬ 
out, up and in’bed, on a journey and in hours even of re¬ 
creation ; and that he learned French and Italian when he 
was old.” He was a man of great goodnefs of difpolition, 
of great humanity, and fincerity in his fearches after truth. 
CAMERA'RIUS (Joachim), fon of the foregoing, and 
deeply veiled in feveral arts, particularly that of medicine,. 
was born at Nuremberg in 1534. He rejected the invita¬ 
tions of feveral princes, who were defirous of having him 
about them, that he might devote liimfelf entirely to che- 
miftry and botany. He died in 1598, aged fixty-eight. 
His works are, 1. Hortus Medicus, Nuremberg, 1654, 4m. 
2. De Plantis, 1586, 4to. 3. F.piftolae. 4. Elefta Geor-
