Mr. Millar affirms that he has cultivated

DOLIOCARPUS, in botany, a genus 
of the Polyandria Monogynia class and or- 
der. Essential character : calyx five-leav- 
ed ; corolla three-petalled, plaited ; stigma 
sub-bifid ; berry globular, crowned with a 
style, one-celled, two-seeded. There are

DOMBEYA, in botany, so called in me- 
mory of Jos. Dombey, a genus of the Dioe- 
cia Monadelphia class and order. Natural 
order of Coniferae. Essential character: 
male, calyx of the ament; scales termi- 
nated by a leaflet; corolla none; anthers 
ten or twelve, without filaments. Female, 
calyx ament, with many germs; corolla 
none ; stigma bivalve, unequal ; seeds many 
in a roundish strobile. There is but one 
species, mz. D. chilensis, a tree very little 
known, of a resinous nature, in some re- 
spects allied to protea; and also to the 
pines in some particulars of its fructifica- 
tion ; the trunk is straight, and of consider- 
able height ; the wood is white, solid, and 
clothed with a kind of double bark. The 
flowers are male and female, borne on dif- 
ferent individuals, and hang in sessile soli-

DOME, in architecture, a spherical 
roof, or a roof of a spherical form, raised 
over the middle of a building, as a church, 
hall, pavilion, vestible, stair-case, &c. by

DOMESDAY, or Dooms-day-book, a 
very ancient record made in the time of 
William the Conqueror, which now i-emains 
in the Exchequer, and consists of two vo- 
lumes, a greater and a less ; the greater 
contains a survey of all the lands in most of 
the counties in England, and the less com- 
prehends some counties that were not then 
surveyed. The book of domesday was be- 
gun by five justices, assigned for that pur- 
pose in each county, in the year 1081, and 
finished in 1086. It was of that authority, 
tliat the Conqueror himself submitted, in 
some cases wherein he was concerned, to be 
determined by it. Camden calls this book 
the tax-book of king William ; and it was far- 
ther called magna rolla. There is likewise 
a third book of domesday, made by com- 
mand of the Conqueror ; and also a fourth, 
being an abridgment of the other books. 
DOMINICAL letter, in chronology, is
