The Cambogia gutta of Linnzus, according to Keenig, alfo affords 
a yellow juice; but this, on drying, acquires a brownith hue, and is 
confidered as a fpurious kind of Gamboge. 
Gamboge is brought from the Eaft Indies, and is well known to 
operate powerfully both upwards and downwards. Geoffroy fays, 
that its emetic tendency is counteracted, if given in combination with 
mercurius dulcis, and that it may be given with lefs danger from its 
violence, in a liquid form than.in fubftance. In hydropic cates it is 
often ufed to quicken the operation of other purgatives. 
Though the ordinary dofe of this cathartic is two or three grains, 
yet for the expulfion of the tape worm it has been given, with an 
a quantity of vegetable anal, to the extent of fifteen grains.

THE tree, from which this refin is obtained, though not yet _ 
botanically afcertained, is known to grow on the banks of the river

Kino immediately iflues drop by drop, and by the heat of the fun is 
formed into a hard mafs. This, which was for fome time confidered 
as a fpecies of fanguis draconis, was afterwards fully explained, and 
its medical character eftablithed, by Dr. John Fothergill. ( Med. Obf:
