markable, that by a statute of 37 Hen.VIII, 
a doctor of civil law may exercise ecclesi- 
astical jurisdiction, though a layman. 
Doctor in music, a musician upon whom 
some university has conferred the degree of 
doctor in the feculty of music. By the qua- 
lifications foi-merly required of a candidate 
either for a doctor’s or batclielor’s degree 
in music, it should seem that the science 
was regarded merely as speculative. The 
present statutes, however, are formed on a 
broader principle, and looking to talent and 
active science for the necessary qualifica- 
tions, require of the candidate an exercise 
in eight vocal parts, with instrumental ac- 
companiments, which he is to submit to the 
inspection of the musical professor, and to 
have performed in the music school, or some 
other public place in the university.

DODECANDRIA, the name of tlie 
eleventh class in Linnaeus’s Sexual System ; 
consisting of plants with hermaphrodite 
flowers, that, according to the title, have 
twelve stamina or male organs. This class, 
however, is not limited with respect to the 
number of stamina. Many genera have 
sixteen, eighteen, and even nineteen sta- 
mina ; the essential chai-acter seems to be 
that, in the class in question, as in Polyan- 
dria, the 13th, the stamina are inserted into 
the receptacle: whereas in the intermediate 
class, Icosandria, which is as little deter- 
mined in point of number as the other two, 
they ai'e attached to the inside of the calyx. 
The orders in this class, which are six, are 
founded upon the number of tlie styles, or 
female organs. Asarabacca, mangostan, 
storax, purple loose-strife, wild Syrian rue, 
and purslane, have one style; agrimony 
and heliocarpus have two ; burning thorny 
plant and bastard rocket three ; glinus five ; 
illiciura eight ; and houseleek twelve. 
DO DEGAS, in botany, a genus of the 
Dodecandria Monogynia class and order. 
Natural order of Calycanthemae. Myrti, 
DOL 
Jussieu. Essential character: corolla five- 
petalled ; calyx half four-cleft, bearing the 
corolla, superior ; capsule one-celled, con- 
nate with the calyx. There is but one spe- 
cies, viz. D. surinamensis, a native of Su- 
rinam. 
DODECATHEON, in botany, a genus 
of the Pentandria Monogynia class and or- 
der. Natural order of Precias. Lysimachiae, 
Jussieu. Essential character : corolla rotate, 
reflex ; stamina placed on the tube ; cap- 
sule one-celled, oblong. There is only one 
species, viz. D. meadia. Virginian cowslip, 
or meadia, has a perennial yellow root, 
from which come out in tlie spring, several 
long smooth leaves, six inches long, and 
nearly two broad ; at first they stand erect, 
but afterwards they lie on the ground, espe- 
cially if the plant be much exposed to the 
sun; from among these leaves arise three 
or four flower stalks, eight or nine inches 
high, they are smooth, naked, and termi- 
nated by an umbel of flowers, of a peach 
coloured blossom ; these appear in April or 
May ; the seeds ripen about July, soon af- 
ter which the leaves decay, and tlie roots 
remain inactive till the following spring. 
It is a native of Virginia, and many parts 
of North America.

DODONjEA, in botany, so named in 
honour of Rembert Dodonffius, a famous

binlaceae, Jussieu. Essential character: 
calyx four-leaved; corolla none; capsule 
three-celled, inflated ; seeds in couples. 
There are two species, viz. D. viscosa, 
broad-leaved dodonaea, and D. angustifolia,

native of the countries between the tropics, 
the latter is found at the Cape of Good 
Hope.

DOLICHOS, in botany, a genus of the

Natural order of Papilionaceae, orLegumi-

oblong calluses at the base of the standard, 
compressing the wings underneath. There 
are thirty-eight species ; most of these are 
annual, and natives either of the East or 
West Indies. They are chiefly herbaceous, 
with twining stalks : the flowers are frequently 
in spikes, and axillaiy ; the legume is often 
smooth, sometimes villose, or pruuient.
