RETINACULUM, the name of a chirurgical inftniment ufed in caftration, and in the operation for a hernia, to prevent the interlines from falling into the fcrotum. RETORT (CycL)— The quantity of air rifing from fome fubftances is apt to burft glaffes in difrilling; Dr. Browne Langrim has therefore given us a new contrivance of ap- plying receivers to retorts, by which fuch accidents may be prevented. To his firil receiver he adapts a fecond, inferted into an opening at the top of the firft, in order to give more room to the rarefied and new generated air. To an opening, at the bottom of each of thefe receivers, he fixes a bottle, tied on clofe by means of a bladder, fo that they may be removed at any time, and another infrantly placed in their room ; by which means very little of the fteam will cfcape. He alfo ties on a bladder to an open- ing) or upper neck of the fecond recipient; and this bladder being much thinner and weaker than any of the glafles, will always give way firfr, and prevent their burfting. And even when there is the greateft danger of this accident, the imalleft pin hole made through the top of the bladder, as foon as the fumes begin to rife, will be fufficient to let out the air as faft as it is generated. See Philof. Tranf. N° 475. Se6t. 3. where we have a figure of the whole apparatus. See alfo Tab. of Chemiftry, N° 22, and 34.
RETREAT, (Cycl.) or Tattou, in the art of war, is a beat of the drum in the evening, at the firing of a piece called the warning piece, at which ihe drum-major, with all the drums of the battalion, except fuch as are upon duty, beais round the regiment ; the drums of the quarter guards, of the generals guards, and all other fmall guards, do like- wife beat j the trumpets at the fame time founding at the head of their refpe&ive troops.

REWARDS. Military reward^ among the Athenians, confid- ed fometimes in crowns prefented to thofe that had merited them; on which their names and noble actions were inferibed. Some had leave granted them to erect, pillars or ftatues, in honour of fome god, with Infcriptions fetting forth their victories. This was a favour that was feldom granted; Cimon indeed was honoured with it, but Themiftocles could never obtain the like. Another honour conferred at Athens on the valiant, was to have their arms placed in the citadel, and to be called Cecropidts, or citizens of the true old blood. Others were prefented with a «7«^oirAi«, or Compleat fuit of armour. Songs of triumph were honorary compliments paid to fome. The children of thofe who were killed in battle were maintained at the public expence, till they came to maturity; at which time they were pre- fented before the affembly of the Athenian people with a Compleat fuit of armour, one of the public minifters pro- claiming before them, " that hitherto, in remembrance of M their fathers merits, the commonwealth had educated f thefe young men, but now difmified them fo armed, to " go forth and thank their country by imitating their fathers " examples."
Solon made a farther pro virion for the parents of thofe that died in the wars, it being extremely reafonable that they mould be maintained at the public expence, who had loft their children, the comfort and fupport of their declining age, in the fervice of the public.
As for thofe who were any wife difabled, they had an al- lowance from the public towards their maintenance. Potter, Tom. 2. p. 118, feq.

REY grafs. This is a hardy fort of graft, much efl-eerried among the farmers for that quality. It will grow on any land, and therefore produces crops where nothing elfe will. It thrives beft of all on fower, clayev, and weeping grounds, and equally endures the fevereft droughts of Cummer, and frofts of winter, fuffering no damage from either. It is the beft of all winter foods for cattle, the ihorter it is eaten the better, and it fprings the earlieft of any. There is no danger of overftocking it, for if it be left to grow too much, the ftalk becomes hard and fticky. It is 'bed for horfes and for flieep, and very much prevents the rotting of the latter. The beft way of lowing it is with clover. The common quantity of feed is two bufhels to an acre, but three bufhels is much better ; though in fome lands, where the clover is likely to fucceed very well, they fow eight pounds of clover feed, and one bufhel of rey feed to an acre, and this makes a crop that will laft feven or eight years. Some mow it as hay, and thrafh it for the feed, which about London fells from half a crown a bufhel to three millings. Four or five quarters of this feed will be fometimes produced from an acre of the grafs. If at any time a field of this grafs is found to grow thin, jt is only neceflary to ftreW on a bufhel of the feed, and roll it with a wooden roller, and the plants rifing from this addition will make the whole crop fufficiently thick. Rey grafs has this great advantage, that it kills weeds without any other fown plant ; even thirties cannot grow among it. When the rey grafs is cut for hay before perfeflly ripe, the hay is the better, but the feed will not grow fo well. When the feed is newly thrafhed, it muft not be laid too thick, for it is very apt to heat and ferment, and the whole will be fpoiled. Mortimer's Huf- bandry, p. 40.
RHABARBARUM, in botany, the name given to the plant of which rhubarb is the root, and which Mr. Tournefort makes to conftitutc of itfclf a peculiar genus, of which there is no other fpecies.
