SCISSORS. Mr. Monro has given us the figure and defcrip- tion of a pair of feijfors, the blades of which are crooked on their flat fides. Thefe fdjfors are very ufeful for taking oft' excrefcences from hollow parts, or for cutting in curve lines, which the common feijfors cannot eafily be applied to. Med. EfT. Edinb. Vol. 5. art. 41.

SCIURUS, the fquirrel, in the Linniean fyftem of zoology, makes a diftincf genus of animals, the characters of which are; that the creatures have four toes on the fore feet, and five on the hinder, wiih palms made for climbing and leaping, and all have woolly tails. Linnai Syftem. Natur. p. 33.

We have five fpecies of this little animal defcribed to lis. 1. The common Englifh kind. 2. The great grey Virgini- an one. 3. The black backed kind of Ceylon. 4. 9 I'he American flying fquirrel. And 5. the Barbary kind. The common Englifh fquirrel is well known, and is di- ftinguifhed from the others by its fize and colour. It is fomething larger than the weafel, but fhorter bodied; its back and fides are reddilh; its throat and belly white; and it generally carries its long hairy tail erecf over its back, fo that it ferves it for a fhade. It is common in our woods, and feeds on all forts ot fruit, but principally on hazel nuts; which it gathers in the feafon, and lays up for its winter ftore. The fame fpecies of fquirrel with ours is found in Poland and RuSia, grey or aih coloured. The fecond, or great grey American jqui rril, is very com- mon in Virginia, and is of the fize of a rabbet. It is of a dark iron grey, fuch as feme rabbets are of; its fore feet have only tour toes, its hinder ones five. The third, or black backed fquirrel, is found in the ifland of Ceylon, and called by fome rukkaia, from the noife it makes. The hair on its back is fometimes grey. The fourth, or flying fquirrd, is a very linall kind; its back is of a dufky moule-coloured grey; its throat and belly White; its eyes fmall, black, and prominent, refembling thofe of the moufe kind; its tail is very long, and very broad and flat. It has a thin and lax fkin on each fide, Which is fixed to the fore ar.u hinder legs, and confequently, on the extending its legs, this (kin expands on each fide like a fort of fail : this it always does in leaping, and is by that means carried a great way; and hence has arifen the opinion of its flying. It is very common in New Spain, and is fometimes met with in the colder American countries. It very much approaches to the moufe kind in many particu- lars, receding from the nature of the fquirrel. Its furr is fhort like that of the rat or moufe, not long like the other fquirrels. It never ereas its tail on its back, nor turns or twifts it round, as the other fquirrels do. It has a very beautiful black line on each fide the face, near the eyes.

The fifth kind, or Ekrbary fquirnel, is of a mixed colour, between black and reddilh, and is very beautifully variegated all down the fides with brown and white longitudinal ftreaks, laid in a regular alternate order, and each reaching the whole length of the body. Thefe lines are, in fome ol" thefe creatures, not brown and white, but black and white;

■ and the tail, when in a ftate of reft, is feen elegantly (beak- ed with the fame colours, but when the creature erefts it, the hairs Handing all upright, the beauty of this variegation is hid. The belly of this creature is blue and white. It is fmaller than our fquirrel, and has fhorter ears, which are loundiih, and lie clofe on the head. The whole head has much of the figure of a frog's, in all other refpects it is per- fectly Kke our fquirrel. Ray's Synop. Quad. p. 2 14.

SCLARI.A, in botany, the name of a genus of plants, the charaaers of which are thefe. The flower confifts of one leaf, and is of the labiated kind; the upper lip is hooked like a reaper's fickle, and the under one divided into three fegments, the middle one being largeft, and hollowed like a fpoon. The piftil arifes from the cup, and is fixed in the manner of a nail to the hinder part of the flower. It is fur- rounded by four embryos, which ripen into as many feeds. and are contained in a fort of tubular capfule, which was the cup of the flower.

The fpecies of fdarea, enumerated by Mr. Tournefort, are thefe. 1. The fdarea, called ^allitrichum fativum and or- vala by authors. 2. The woolly fdarea with very large flowers, called Mtbupis by many authors. 3. The jagged leaved felarea, called the Mthiopis with divided leaves. 4 .The large leaved glutinous Portugal fdarea. 5.

Of this there were two fpecies;, the one found native in the earth, the other fiaitious.

The latter kind was prepared by rubbing a quantity of vi- negar in a brafs mortar, with a brafs peftle, till it became thick and ropy; when it was in this condition, a fmall quantity of alum and fea fait, or nitre, were added to it, and it was fet in the fun in the heat of the dog days. It was to ftand thus till it became ropy, thick, and of a green colour; and then being drawn out into long threads, and dried, it h:; d the refemblance of worms in fhape, and thence had its name.
