T H R I P g. 
To feel a sharp tingling sensation. 
To seek sweet safety out. 
In vaults and prisons; and to thrill and shake, 
Ev’n at the crying of our nation’s crow. 
Thinking his voice an armed Englishman. Shakspeare. 
To pass with a tingling sensation. 
A faint cold fear thrills through my veins, 
That almost freezes up the heat of life. Shakspeare. 
THRILL, s. The breathing place or hole.—The bill of 
the dodo hooks and bends downwards; the thrill or 
breathing-place is in the midst. Sir T. Herbert. —A 
piercing sound. 
THRIMBY, a hamlet of England, in Westmoreland; 9j 
miles north-north-west of Orton. 
THRIMSA, in Antiquity, a silver coin, the value of which 
has occasioned a variety of conjectures. Lambard, who 
gave the first estimate of it, makes it a three-shilling piece, 
in which opinion he is followed by Sir Henry Spelman. 
Bishop Nicholson apprehends, that it was the name of their 
common coin, and that the thrimsa sceata, and penny, were 
all of them the same. Somner, from the import of the word, 
and the value given to the thrimsa in the Saxon laws, rates 
it at three-pence. Selden, Brady, and Hickes, are of opinion, 
that this coin was either the last tremissis of the Franks and 
Germans, and consequently four-pence, or the third part of 
the Saxon shilling, i. e. three half-pence and one-third of a 
halfpenny in their money. 
THRIN, a river of England, in Norfolk, which runs into 
the sea, near Yarmouth.

To THRIN G, v. a. [Spmgan, Sax.] To press; to thrust, 
still used in some parts of the north. It is, in fact, no other 
than throng; and in our old language, is both active and

THRIPS, a name used among the ancients to express a 
sort of worm hatched from the egg of a beetle. 
THR1PS, a genus of the order of Hemiptera, the charac¬ 
ters of which are, that the rostrum is obsolete, being hidden 
within the mouth ; the antennae filiform, and as long as the 
thorax: the body sleuder, and of equal thickness; the abdo¬ 
men reflexible, and often bent upwards ; the four wings 
extended, incumbent, narrow, and crossing one another at 
some distance from their base. The thrips has six feet, 
and the tarsus of each foot has only two articulations, 
Gmelin enumerates the following eleven species. 
1. Thrips paradoxa.—Brown, with abbreviated wings, 
and antennae pectinate, fissile and filiform.-—Found in China, 
but Gmelin doubts whether it be of this genus. 
2. Thrips physapus.—With glaucous elytra or shell- 
wings, and black body.—Found frequently on flowers in 
Europe. 
3. Thrips minutissima,—With glaucous elytra and body, 
and brown eyes.—Found as the former. 
4. Thrips juniperina.—With snowy elytra and brown 
body.—Found in the galls of the juniper. 
5. Thrips ulmi.—Black, with snowy ciliated wings, and 
acuminated anus.—Found gregarious on the bark of the elm. 
6. Thrips urticae.—Yellow, with whitish elytra.—-Found 
solitary on the leaves of the nettle, vine, and hazle. 
7. Thrips fasciata.—With elytra banded with white and 
black, and brown body.—Found on flowers in Europe. 
8. Thrips fusca.—Blackish, with glaucous elytra.—Found 
in Denmark: the female probably fasciated ? 
9. Thrips obscura.—Yellowish, with palish elytra, and eyes 
and wings of the abdomen black.—Found in Denmark. 
10. Thrips rufa.—Red.—Found on the spikes of wheat; if 
it be not the larva of the minutissima. 
11. Thrips variegata.—Variegated.—Found on flax. 
The thrips is highly injurious and destructive to many 
sorts of fine fruited trees, but particularly so to those of the 
grape or vine kind. The best and most effectual means of 
preventing its mischievous effects, in such cases, is probably 
that of frequent good washing of the trees with common 
water, by the engine or otherwise. It has lately been ad¬ 
vised that this should be done every evening, as, when per¬ 
formed in the heat of the sun, tire vines are materially injured. 
Indeed all such trees should, it is supposed, be well washed 
every evening, until the berries begin to colour, whether 
infested with insects or not, but especially in the former state ; 
after which it is to be wholly discontinued. 
Where there is a neglect of washing the trees in this or 
some other way, the thrips, for the most part, makes its ap¬ 
pearance. In such cases, these insects may without much 
difficulty be destroyed by the fumigation of tobacco and 
damp hay ; the plants or trees being well washed after it by 
pure water. 
The white bug is another insect which is often very hurtful 
to peach-trees and vines in forcing-houses; and the cause of 
which is believed to be much owing to the trees not being 
daily properly washed in the above manner. Each of these 
sorts of trees stand in need of particular management in clear¬ 
ing them of this insect. 
The brown-bug too occasionally makes its appearance on, 
and is hurtful to peach-trees in such situations, especially 
when they are shaded, or approach near the flues of the 
houses. Proper washing of the trees, in these cases, with 
lime-water, in the winter season ; and syringing them with 
it as soon as the leaves have fallen off, are often very effectual 
in removing such insects. 
The green-fly is also very destructive to peach-trees, espe¬ 
cially when in the forcing state. These are the most effec¬ 
tually destroyed by means of well washing the trees daily in 
a regular manner, after the work of forcing is begun. It- 
is the common practice of most gardeners to discontinue 
such washings as soon as the flowers begin to make their 
appearance, but others have lately continued them wilh sup¬ 
posed advantage, and not found to prevent the fruit from 
setting. If any flies of this, sort present themselves, they 
may be kept under by proper watering or washing, as 
above, and by carefully picking off - the first buds on which 
they appear, which is found to prevent them from breeding, 
and to render the use of tobacco-smoke unnecessary. Fu¬ 
migations of this substance are, however, sometimes bene¬ 
ficial in these cases in removing the vermin. 
This and the blue-fly too are often very injurious to plum- 
trees, especially after they have been affected ' with the 1 
honey-dew. The manner of getting rid of them in such 
cases,
