 the general dilTolution in 1540, when the fcitc and mod of 

 the demefnes were granted to fir William Pickering. At

 of Stapylton.

THIRST, a painful fenfation, occafioned by a vellica- 

 tion of the nerves of the throat or fauces, and producing a 

 defire of drinking. See Dioestion. 



Third may be fometimcs eluded by rolling a clean bullet

Mr. Boyle mentions a man who could eafily abftain fi-om 

 drinking for nine days, and yet have his diet nothing more 

 liquid than ufual ; the fecretions of urine, fweat, &c. being 

 performed all the while regularly, and in the fame quantity 

 as ufual. 



In dropfical cafes, where there is not a right fecretion of 

 the urine by the renal glands, and tlie vcffels and parts of 

 tJie body are loaded with too great a quantity of ferous 

 humours, a great moderation in drink might be attended 

 with good fuccefs, provided fomc liquor could be found 

 out to allay that uneafy fenfation. Probably this would be 

 beft performed by mucilages acidulated with fpirit of vitriol 

 or fulphur, or jellies with juice of lemon, &c. and that a 

 fmall quantity of fuch a compofition, now and then ufcd, 

 might be of as much real fervice, in quenching third, as 

 draughts cf liquors, which increafe the fymptoms. 



In feverifh diforders, the patient is frequently tormented 

 with a violent third, which is moderated by acidulating the 

 barley-water, or fage-tea, with fpirit of vitriol, or with 

 lemon-juice : but by nothing fo much, as allowing the 

 patient fome dices of an orange. Pringle, Obferv. on Dif- 

 cafes of the Army, p. 135. 



THIRSTY Sound, in Geography, an inlet or bay on the 

 N.E. coad of New Holland, fo called by Cook in 1770, 

 becaufe it afforded no fre(h water. It lies in S. lat. 22° 10', 

 and W. long. 210' 18'; and may be known by a group 

 of fmall iflands lying under the (hore, from two to five 

 leagues didant, in the dircftion of N.W., and by another 

 group of iflands that lie right before it, between three and 

 Four leagues out at fea. In this inlet is good anchorage in 

 7, 6, 5, and 4 fathom ; and here are places very convenient 

 for laying a fliip down, where, at fpring-tides, the water 

 does not rife lefs than 16 or 18 feet. The N.W. point of 

 Thirdy Sound was called " Pier-Head."

 • .J^^S'^'LE, in Agriculture, a well-known prickly trou- 

 bleiome weed, common in corn and other fields. It has 

 been obferved, that wherever thidles grow naturally, it is a 

 iure fign that the land is ftrong, and of a tolerable good 

 quality ; but that they ai'e at the fame time a great annoy- 

 aace to every plant intended to be cultivated. And it has 



T H I 



alfo been well remarked, that there are no weed-plants over 

 which the economical farmer ought to keep a more watchful 

 eye than the thidlc tribe, as they are not only wholly ufe- 

 lefs, but occupy much ground, and being furniflied with 

 downy feeds, are capable of being multiplied and car- 

 ried almod to any didance. Befides, they do much mif- 

 chief by impeding the work both in handUng hay and corn 

 crops. It is of courfe a matter of much confequence to be 

 well acquainted with the qualities of each kind, in order 

 to enable the farmer to judge with certainty how far and by 

 what means their dedrudlion may be effefted in the moil 

 certain and ready manner. 



There are a great many forts of thidles ; and thofe which 

 chiefly dcfcrve the attention of the farmer, are the annual, 

 biennial, and^crennja/ kiuds. 



There are four of thefe plants belonging to the fird divi- 

 fion or fort, namely, the mujk-thijlle, which grows to the 

 height of two or three feet ; the heads hang down, and the 

 flowers fmell fomewhat like muflc. It is frequently found 

 occupying whole fields, particularly where the lands are of 

 a chalky or barren quality ; and fending forth flowers in 

 July and the following month in great abundance. The 

 milk-thijlle, which is found plentiful in mod wade places, 

 and upon old banks, being well known by its beautiful 

 large leaves, which are variegated with white fpots and 

 veins, as if they had been fprinkled with milk. The flow- 

 ering feafon of this plant is in Augud, or thereabouts. The 

 ivelted or curled thidle, which is frequently met with on 

 banks, and by- road-fides, but feldom intruding itfelf into 

 fields or paftures. Its time of flowering is June and the 

 following month. See Carduuj. 



And the common foiu-thiflle, which is a very troublefome 

 weed in fields and gardens ; it is found in fome fituations 

 that the plant is fmooth, but in others that it is rough, being 

 prickly on the margins and mid-ribs of the leaves, and alfo 

 on the peduncles and calyces of the flowers, and the dems 

 or dalks abound with a laftefcent or milky juice. See 



SONCHUS. 



But in the fecond divifion, or biennial kind, there are not 

 more than three, as the /fear or bull-thifih, which rifes about 

 three or four feet in height, the extremity of each leaf 

 running out into a long fliarp point, remarkably prickly : 

 hence, in fome places it is called by the name of the buU- 

 thidle. It has large heads of flowers, and commonly grows 

 by the fides of roads, near dunghills, and not unfrequently 

 in fields and padures, flowering in June and the following 

 month : the marjh-thijlle, which grows very tall and prickly, 

 having numerous heads of flowers, fmall and of a red co- 

 lour, growing abundantly in wet meadows and in woods, 

 flowering in July and the month which fucceeds it. See 

 Carduus. 



And the cotton-thijlle, which is found plentifully in uncul- 

 tivated places in many parts. The roots are long and 

 fibrous, and fend forth (everal oblong ftiarp-pointed whitifti- 

 green finuated leaves, covered with a cottony down, and 

 fet with fpines on tlieir edges. In the middle of thefe 

 ftioots up a ftalk, to the height of five or fix feet, divided 

 towards the top into diverfe branches, fet with leaves at 

 their joints, and having jagged, leafy borders running along 

 them, edged with fpires, as has the main dalk alfo. Each 

 branch terminates with a fcaly head of reddifh purple flo- 

 rets, having narrow tubes, and cut at their brim into five 

 teeth. They contain flowers, which are fucceeded by 

 fmall oblong feeds crowned with down. The time of its 

 flowering is about July, for the mod part. See Onopor- 



DUM. 



And in the third divifion or fort there are only two ; as
