1'OfKNT, in general, is the tenden- 

 cy of a body from a higher to a lower 

 place ; thus all bodies, unless otherwise 

 determined by a force superior to their 

 gravity, descend towards the centre of 

 the earth : the planets too may be said 

 to descend from their aphelion to the 

 perihelion of their orbits, as the moon 

 does from the apogee to the perigee. 

 Heavy bodies, meeting with no resistance, 

 descend with an uniformly accelerated 

 motion, for the laws of which see MKCHA- 



l)i:<( F.VT, or hereditary succession, is 

 the title of which a man on the death of 

 bis ancestor acquires his estate by right 

 of representation, as his heir at law : and 

 an estate so descending to the heir is in 

 law called the inheritance. 



Descent is of three kinds ; by common 

 law, by custom, or by statute. By com- 

 mon law, as where one hath land of in- 

 heritance in fee-simple, and dieth without 

 disposing thereof in his life-time, and the 

 1 and goes to the eldest son and heir of 

 course, being cast upon him by the law. 



Descent of fee-simple by custom is some- 

 times to all the sons, or to all the brothers 

 (where one brother dieth without issue), 

 us in gavel-kind ; sometimes to the young- 

 est son, as in borough English ; and some- 

 times to the eldest daughter, or the 

 youngest, according to the customs of 

 particular places. Descent by statute is 

 of fee-tail, as directed by the statute of 

 minster, 2. dc donin. 



NT, in genealogy, the order or 



succession of descendants in a line or 



ta-nily ; or their distance frotn^a common 



progenitor. Thus we say, one descent, 



cents, ike. 



1) -IKNT, in heraldry, is used to ex- 

 'ie coming down of any thing from 

 above ; as a lion en descent, is a lion with 

 his head towards the base points, and his 

 heels towards one of the corners of the 

 chief, as if he were leaping down from 

 some high place. 



I)KS( KNT, in fortification, are the holes, 

 vaults, and hollow places, made by under- 

 mining the ground.

 whereof the upper partis covered with

 this trench is on a level with the - 

 of the water, but in dry ones it is sunk as 

 dei p as the bottom of the ditch.

iiu'Tio.N. In deeds and grants 

 there must be a certain description of the 

 lands granted, the places where they lie, 

 and the persons to whom granted, ike. to 

 make them good. But wills are more fa- 

 voured than grants as to those descrip- 

 tions; and a wrong description of the 

 person will not make a devise void, if 

 there be otherwise a sufficient certaint) 

 what person was intended by the testa- 

 tor. Where a first description of land, 

 &.c. is false, though the second be true, 

 a deed will be void : contra, if the first 

 be true and the second false. 



DESCRIPTION, applied to botany, the 

 natural character of the whole plant, in- 

 cluding all the external parts. In this 

 respect the description of the species is 

 distinguished from the specific difference 

 which regards the essential or striking 

 characters only. A perfect, or complete 

 description, is not confined to the princi- 

 pal parts of plants, as the root, stem, 

 leaves, and fructification ; but includes, 

 likewise, whatever is conspicuous in their 

 external appearance: as the foot-stalks of 

 the leaves and flower; the stipulx, or 

 scales; the bractez, or Moral leaves ; the 

 glands, or vessels of' secretion ; the wea- 

 pons of offence and defence; the buds ; 

 the complication, or folding of the IC^N es 

 within the buds ; and the habit or gene- 

 ral appearance of the whole plant. The 

 order to be observed iu tile description is 

 that of nature, proceeding from the root 

 to the stem ; next the branches; then the 

 foot-stalks, leaves, flow tr-stalks, and 

 flowers.
