ACC 
abdomen beset on its hind part with numer- 
ous white bristles. It attaches itself to the 
skin, and is with difficulty disengaged. On 
the part where it fixes, it causes a tumour, 
about the size of a small bead, accompanied 
by a severe itching. The tick is 'of this 
species, which is to be found on dogs and 
other animals. Many of the acari attach 
themselves to insects ot a larger kind, and 
hence they take their names, as A. coleopte- 
rous, found on the black beetle. (See plate 
I. Entomology, fig. 1 and 2.) 
These insects, which are often very trouble- 
some on plants, and in hothouses, may be 
effectually destroyed by the following mix- 
ture. Take two ounces of soft green soap, 
one ounce Of common turpentine, and one 
ounce of flour of sulphur ; pour upon these 
ingredients a gallon of boiling water, work 
the whole, together with a whisk, and let the 
mixture be used warm. This mixture may 
also be of use for preventing the mildew on 
the peach and apricot ; but it should never 
be used on fruit-trees near the time when 
their fruits are ripening. A strong ley 
made of wood-ashes will likewise destroy 
the acari ; but plants are greatly injured 
by this, and by briny and spirituous compo- 
sitions. 
ACAULOSE, or Acaci.ous, among bo- 
tanists, a term used for such plants as have 
no caulis, or stem. See Caulis. 
ACCEDAS ad curiam, in law, a writ ly- 
ing where a man hath received, or fears 
false judgment, in a hundred-court, or court 
baron. It is issued out of the Chancery, 
and directed to the sheriff, but returnable 
in the King’s-bench or Common-pleas. It 
lies also for justice delayed, and is said to be 
a species of the writ Recordare. 
ACCELERATION, in mechanics, de- 
notes the augmentation or increase of mo- 
tion in accelerated bodies. 
The term acceleration is chiefly used in 
speaking of falling bodies, or the tendency 
of heavy bodies towards the centre of the 
earth produced by the power of gravity; 
/ which, acting constantly and uniformly upon 
them, they must necessarily acquire every 
instant a new increase of motion. See 
Gravitation. 
ACCELERATOR. See Anatomy. 
ACCENT, among grammarians, is the 
raising or lowering of the .voice in pronounc- 
ing certain syllables of words. 
We have three kinds of accents, viz, the 
acute, the grave, and circumflex. The acute 
accent, marked thus ('■), shews that the 
voice is to be raised in pronouncing the 
ACC 
syllables over which it is placed. The grave 
accent is marked thus ('), and points out 
when the voice ought to be lowered. The 
circumflex accent is compounded of the 
other two, and marked thus (" or '•) : it de- 
notes a quavering of the voice between high 
and low. Some call the long and short 
quantities of syllables, accents; but erro- 
neously. 
Accent, in music, a term applicable to 
every modulation of the voice, ‘"both in 
speaking arid in singing. It is to the study 
of this that the composer and performer 
should unceasingly apply ; since without ac- 
cent there can be no music, because there 
can be no expression. . 
ACCEPTANCE, in common law, the 
tacitly agreeing to some act before done by 
another, which might have been defeated 
without such acceptance. Thus if a hus- 
band and wife, seized of land in right of the 
wife, make a joint lease or feoffment, re- 
serving rent, and the husband dies ; after 
which the widow receives or accepts the 
rent ; such receipt is deemed an acceptance, 
confirms the lease of feoffment, and bars 
her from bringing the writ cui in vita. 
Acceptance, among merchants, is the 
signing or subscribing a bill of exchange, 
by which the acceptor obliges himself to 
pay the contents of the bill. 
Bills payable at sight are not accepted, 
because they must either be paid on being 
presented, or else protested for want of 
payment. 
The acceptance of bills payable at a fixed 
day, at usance, or double usance, &c. need 
not be dated : because the time is reckoned 
from the date of the bill ; but it is necessary 
to date the acceptance of bills payable at a 
certain number of days after sight, because 
the time does not begin to run till the next 
day after that acceptance : this kind of ac- 
ceptance is made thus, Accepted such a day 
and year, and signed. See Exchange. 
ACCESSARY, or Accessory, in com- 
mon law, is chiefly used for a person guilty 
of a felonious offence, not principally, but 
by participation ; as, by advice, command, 
or concealment. There are two kinds of 
accessaries; before the fact, and after it. 
The first is he who commands, or procures 
another to commit felony, and is not present 
himself; for if he he present, he is a prin- 
cipal. 
The second is he who receives, assists, or 
comforts any man that has done murder, or 
felony, whereof he has knowledge. A man 
may also be accessary to an accessaiy, by
