of glass. But as the labour increases by 
adhesion of the cushion, tne stronger the 
excitation, it seems as if the strength of a 
man would be more profitably employed in 
turning two or more plates, or cylinders, at 
the intensity of thirty ^feet, than at any 
higher intensity ; besides which, this power 
is less variable, and may last five or six 
hours without requiring fresh amalgam. 
The vulgar notion of electricity is, that 
it is fire which passes in a spark from one 
body to another. From its passage through 
dense conductors, as well as through the 
air, it seems to move with extreme velocity ; 
and this may be sufficient, without suppos- 
ing it to be essentially luminous, to account 
for the ignited appearance it affords, in all 
non-conductors, whether air, or oil, or 
glass, or wood, &c. and even in metal, 
when the conductor is small. If oxygen be 
present, these bodies will have their com- 
bustible parts burned ; and if not, a de- 
composition of those parts which are ignited 
may ensue. 
EXCLAMATION, in rhetoric, a figure 
that expresses the violent and sudden break- 
ing out, and vehemence of any passion, 
Such is that in the second book of Milton’s 
‘‘ Paradise Lost 
“ O unexpected stroke, worse than of 
death ! 
Must I thus leave thee, Paradise ? Thus 
leave 
Thee, native soil ; these happy walks and 
shades, 
Fit haunt of gods !” 
Other figures are the language of some par- 
ticular passion, but this expresses them all. 
It is the voice of nature, when she is in 
concern and transport. 
EXCLUSION, or Bill of Exclusion, a 
bill proposed about the close of the reign 
of King Charles II. for excluding the Duke 
of York, the King’s brother, from the 
throne, on account of his being a papist. 
Exclusion, in mathematics, is a method 
of coming at the solution of numerical pro- 
blems, by previously throwing out of our 
consideration such numbers as are of no 
use in solving the question. 
EXCLUSIVE is sometimes used adjec- 
tively, thus : “ A patent carries with it an 
exclusive privilege ;” and sometimes adver- 
bially, as, “ He sent him all the numbers 
from N° 145 to N° 247 exclusive that is, 
all between these two numbers, which 
themselves were excepted. 
Exclusive propositions, in logic, are 
EXE 
those where the predicate so agrees with its 
subject, as to exclude every other. Thus, 
“ Virtue alone constitutes nobility,” is an 
exclusive proposition. 
EXCOECARIA, in botany, a genus of 
the Dioecia Triandria class and order. Na- 
tural order of Tricoccag. Euphorbiae, Jus- 
sieu. Essential character : ament naked ; 
calyx and corolla, none ; styles three ; cap- 
sule, tricoccous. There are two species ; 
viz. E. agallocha and E. Cochin Chinensis. 
EXCOMMUNICATION, in law, is 
of two kinds, the less and the greater, 
which last is the highest ecclesiastical cen- 
sure which can be pronounced ; for thereby 
the party is excluded from the body ot the 
church, and disabled from bringing any ac- 
tion in the common law courts ; he is also 
disabled to serve on juries, or to be a wit- 
ness in any cause ; he cannot be attorney 
or procurator for another; he is to be turned 
out of the church by the churchwardens, 
and not to be allowed ehristian burial. He 
may also, in some cases, be imprisoned un- 
til he submits to the ecclesiastical jurisdic- 
tion, as in case of refusing to answer to a 
suit for tithes. 
EXCORIATION, in medicine and sur- 
gery, the galling or rubbing off of the cuti- 
cle. To remedy this, the parts affected may 
be washed often with warm water, and 
sprinkled with drying powders, as chalk, 
hartshorn, but especially tutty, lapis cala- 
minaris, and ceruse, which may be tied 
loosely in a rag, and the powdev shook out 
on the disordered places. 
EXCREMENT. See Feces. 
EXCRESCENCE, in surgery, denotes 
every preternatural tumour which arises 
upon the skin, either in the form of a wart 
or tubercle. 
EXCRETION, or Secretion, in me- 
dicine, a separation of some fluid, mixed 
with the blood by means of the glands. See 
Secretion. 
EXCRETORY, in anatomy, a term ap- 
plied to certain little ducts or vessels, des- 
tined for the reception of a fluid, secreted 
in certain glandules, and other viscera, for 
the excretion of it in the appropriated 
places. 
EXECUTION, in law, is a judicial writ, 
grounded on the judgment of the court 
whence it issues; and is supposed to be 
granted by the court, at the request of the 
party at whose suit it is issued, to give him 
satisfaction on the judgment which he hath 
obtained; and therefore an execution can- 
not be sued out in one court, upon a judg-
