plays, where the actors fpoke. But this feems an error in that great critic, for they fecm, by what hiftories we have left of them, to have been reprefented fingly long before that time, Pylades living in the time of Auguftus Csefar. Poetry and dancing were early fuppofed to have fome re- lation to one another ; the firft was called a [peaking dance, and the latter a dumb poem ; a name afterwards, and not till long afterwards, given to a piflure. Thus they were in- troduced on the fame fcenes, as things naturally connected together.

Scent bags, in natural hiftory, a name given by Tyfon to thofe peculiar pouches, or bags, which certain animals, as the civet cat and mufk animal, have for the receiving the mat- ter of their perfume. Thefe bags are common to more animals than is generally fuppofed, and in all have much the fame qualities, the matter they contain being in mod of them feet id, and disagreeable, while contained in the bag, and only becoming fweet and pleafant when dried, or taken at lead: from the animal, and fmelt in fmall quantities. The weafcl and polecat with us have bags of this kind, and the famous bag, or pouch of the opoflum, is of the nature of thefe ; though it ferves alfo to the other great purpofe of re- ceiving and flickering the young in time of danger. It contains, like the reft, a tough and vifcous matter, which ouzes out of the glands, and is of a very offenfive fmell while the creature lives ; but as foon as it is taken out and dried, the fmel! changes into a fine perfume. The gland of the aper mofchiferus, as Tyfon calls it, is of this kind, con- taining a glutinous humor of a very offenfive fmell when frefh, but when dried, becoming fweet and perfumed as mufk.

There is no flower of petals. The ftamina are fix very fhort and flaccid capillary filaments. The anthera? are ereel and obtufe, very long, and of a compreffed figure. The germina of the piftils are three in number; they are of the fize of the cup, and of an oval compriiicd figure; though there be no ilyle. The ftigmata are oblono-, and obtufe on the upper part ; they grow on the outfide to the germina. The fruit confifts of as many capfules as the piftil had germina ; they are of a roundifh figure, inflated and comprefled, and each compofed of two valves. The feeds are Angle and oblong.

The number of the germina and capfules vary, from three up to fix ; the three feem, however, the moft natural ftate of the flower, and are the moft frequent. Linneei Gen. Plant, p. 152.

The ftamina arc a confi- derable number of oblong flender filaments. The germen of the piftil is roundifh, and the fruit is a globofe berry, containing a large feed of the lame globofe figure. This plant, in its external appearance, refembles very much the rbus and the lentijk, m the fru&ification, but when clofely examined, is found to differ from both ; from the former, in having more than five ftamina, and from the latter, in the petals.
