DIAPERED, or DIAFHE, in heraldry, 

 the dividing of a field in planes, like fret- 

 work, and tilling the same with variety of 

 figures. This chiefly obtains on bordures 

 which are diapered or fretted over, and 

 the fret charged with tilings proper for 

 bordures. Baron renders it vuriutus, 

 which is not sufficient to express the se- 

 veral things of which it is variated. 



DIAPHANOUS, an appellation given 

 to all transparent bodies, or such as trans- 

 mit the rays of light. 



DIAPHORETICS, among physicians, 

 all medicines which promote perspira- 

 tion. 



DIAPHRAGM, in anatomy, a large, 

 robust, niusculous membrane or skin, 

 placed transversely in the trunk, and di- 

 viding the thorax from the abdomen. See 



AxAfOMT. 



DIARRHOEA, in medicine, is a fre- 

 quent and copious evacuation of li- 

 quid excrement by stool. See Mtjii- 

 nra. 



DIASTOLE, among physicians, sig- 

 nifies the dilatation of the heart, auri- 

 cles, and arteries ; and stands opposed 

 to the systole, or contraction of the same 

 parts. 



DIASTOLE, in grammar, a figure of 

 prosody, whereby a syllable naturally 

 short is made long : such is the first syl- 

 lable of Priamides in the following verse 

 of Virgil. 



JUtque hie Priamidea : nifal o tibi, amice, 

 rclictum. 



This figure is used either out of mere 

 poetic license, without any necessity for 

 so doing, or through necessity, for the 

 sake of the verse ; as when three or more 

 short syllables follow each other in hex- 

 ameter verse. 



DIATESSARON, among ancient mu- 

 sicians, a concord or harmonica! inter- 

 val, composed of a greater tone, a less 

 tone, and one greater semi-tone : its pro- 

 portion in numbers is as 4 : 3. The word 

 diatessaron has been of late used by se- 

 veral authors for a harmony of the four 

 gospels. 



DIBBLING, in agriculture, a mode of 

 setting corn, or other seeds, practised 

 with advantage in places where labour is 

 cheap ; it is chiefly used for putii ng wheat 

 crops into the ground. The practice of 

 dibbling was first introduced into Nor- 

 folk, about 25 years ago. The method 

 of dibbling is this : when the land is 

 ploughed and rolled, a man with an iron 

 dibble of about three feet long in each 



hand, walking backwards, makes two 

 rows of holes in each furrow, at about four 

 inches distance from each other, and an 

 inch or two deep. The dibbler is fol- 

 lowed by two or three women, or chil- 

 dren, who drop two or three grains into 

 each hole. The field is afterwards bush- 

 harrowed. The usual quantity of seed it 

 from a bushel and a half to two bushels 

 per acre, and the expense of labour about 

 ten shillings. An experienced dibbler, 

 with three active attendants, will plant 

 half an acre a day, making six holes in 

 every foot length. 



DICE, among gamesters, certain cu- 

 bical pieces of bone or ivory, marked 

 with dots on each of their faces, from 

 one to six, according to the number of 

 faces. 



Sharpers have several ways of falsify- 

 ing dice : 1. By sticking a hog's bristle in 

 them so as to make them run high or low 

 as they please. 2 By drilling and load- 

 ing them with quicksilver ; which cheat 

 is found out by holding them gently by 

 two diagonal corners; for, if false, the 

 heavy sides will turn always down. 3. 

 By filing and rounding them. But all 

 these ways fall far short of the art of the 

 dice makers; some of whom are so 

 dextrous this way, that sharping game- 

 sters will give any money for their assis- 

 tance.

 Polyandria Monogynia class and order. 

 Essential character : petals four or five, 

 obovate, trifid ; nectary four or five 

 emarginate corpuscles ; anthers two
