tJNCIFORME Oj, in the carpus, is the fourth bone In the fe- conii row) it has its name from the Latin uncus, a hook, and is compofed of a body, and a hooked or uniform apophy- sis. This apophyfis, which is one of the four eminences on the concave or inner furface of the carpus^ is flat, and the hol- low fide of its curvature is turned toward the os magnum. The outer furface of its body is rough, and in fome meafure trian- gular ; it compleats the convex fide of the carpus, and, to- ward the ulna, terminates in a fmall tuberofity, which is all the cubical fide of this bone.
It has three articular or cartilaginous fides, one radial, one brachial, and one digital. The radial fide is double, anfwer- ing to the cubital fide of the os magnum. The brachial fide is very oblique, fome part of it being gently concave, the reft gently convex, anfwering to the digital fide uf the os cunei- forme. The digital fide is double, or diftinguifhed into two " halves, by a figmoide angular line, for its articulation with , the two laft bones of the metacarpus. Winjlo%v\ Anatomy.;

UNDERWOOD, (Cycl.)— In the cutting the Underwood of coppices* when the (tubs are great, they mould be ftubbed up, for they only take up a great deal of room, and fend up few fhoots, their cracks and hules letting in water, and ufually half killing them. The taking up thefe fhould be performed in win- ter, and the fpaces they leave will be foon occupied by young trees, if not, along branch of fome neighbouring tree may be laid down, and will foon fend up a fufEcient fupply of fuckers for the place.
In felling the Underwood * it is always proper to leave young .trees enough. The worft of thefe may be taken down the next fall, efpecially if any of them grow near a great tree that will be fit to fell the next feafon, becaufe they may be fpoiled by its fall. When trees are at their full growth, there are fe- veral figns of their decay, as the withering or drying of their top branches; their taking in water at fome of their knots, their being hollow or difcoloured, and their making but fmall moots. If wood-peckers make holes in the body, it is a bad fign, and according to the appearance of one or more of thefe fymptoms, it is very propeF to cut down the tree before it de- cays farther. Large and fpreading trees in coppices are often of more mifchief than advantage, as they fpo'il a great deal of the Underwood by their droppings.
The owner of a coppice mult be very careful when he fells the wood ftanding, by the acre, to mark beforehand what ftand- ards are to be left, elfe the purchafer feldom fails to cheat him, by felling fome of them. Mortimer's, Hufbandry, vol. 2.

SuppL UNEDO, in natural hiftory, a name ufed by the antients for a fruit which they recommend as cooling and fub-aftringent. The generality of the world are lead into a common error of believing this to be the fruit of the arbutus or ftrawberry-tree. Pliny has given occafion to this error, by faying exprefsly that the Unedo is the fruit of the arbutus ; but we find this to be contrary to the practice of all the antient Latin writers, who have always called the fruit by the fame name with the tree,' not by a different one. Varro de re Ruftica, (peaking of ga- thering the autumn fruits, calls them all by the name of the trees ; and among them, mentioning the fruit of the arbutus, he exprefl'es it in the fame manner, not by the word Unedo,. decerpendo arbutum mora pomaq_uc : And both Galen and Paulus iEgineta deny the Unedo to be the name of the fruit of the arbutus or ftrawberry-tree, and make it the fruit of the epimelis. Servius explains the word Unedo- by the fruit of the itraw berry -tree j but in this he too ramly follows Pliny's opi- 3 -

We have, in the Philofophical TranfacUons, an account of a young fellow, whofe finger ends were, as it were, armed with hums inftead of nails j they grew to a very amazing length, but then would wear away, or drop off at the ends. The horny excrefcencc on the thumb was the longeft on each hand, and next to it was that of the middle finger, the re-it being gra- dually fhorter ; his feet were well armed with the fame fort of weapons, only that the two little toes had none of them.' Thefe horns feemed to owe their origin to a thickening of the body of the nails, which, inftead of growing out in length in the common way, elevated themfelves in "height from the back ; and when they had rifen to a certain height in this di- rection, they turned downward, and became crooked, fo as to reprefent a bird's claw, only that it was not taper and fharp, but all of the fame thicknefs, and blunt at the end. The upper or convex part of each was marked with a great many chaps, but the concave or under part was fihooth-
