 particularly ferviceable in female obllruitions, paralytic dif- 

 orders, and when continued for a long time, in rheumatic, 

 ifchiadic, and gouty pains. It was denominated by fome 

 of the ancient botanills yua arlhritna, from its ufe in ar- 

 thritic pains. It has been recommended by foreign writers 

 in (low fevers, allhma, and apoplttlic feizures ; and alfo in 

 infarttions of the vifcera and jaundice ; and externally for 

 cleanling and confolidating ulcers, as well as for an antidote 

 to the cancer. But its medical reputation has, in later 

 times, conliderably declined. Lewis's Mat. Med. Murray

The fuit fpecics of Ajuga may be propagated by feeds, 

 fown when they are ripe in a pot filled with earth, and 

 placed in a lliady fituation till Autumn, and then removed 

 under a frame. In the Spring, they fhouldbe tranfplanted 

 into feparate pots. In the hard froft of Winter they 

 fhould be covered. This fpecies may be alfo more flowly 

 inereafed by ofi-sets, of which it affords but a few. The 

 lixth fort may be propagated in the fame manner. As for 

 the rert, they are hardy and eafily multiplied by the fide 

 flioots : they delight in a moill (liady fituation, and are apt 

 to fpread too much. Martyn.

AiUS LoQ_UENS, or Locutius, i.e. a fjient'wg voirr, 

 in Mythology, the name of a Roman deity, to whom a tem- 

 ple was eretted at Roirre, on the following occafion. — M. 

 Cxditius, a plebeian, informed the tribunes, that, as he 

 was paffing through the New Street in the night, he heard 

 a fupernatural voice near the temple of N'^ella, which warned 

 the Romans of the approach ot the Gauls ; but the warn- 

 ing was difregarded on account of the meannels of the 

 perfon who reported it, in confequence of which, the Ro- 

 mans fuffered very much from their invafioii. Camillas, 

 however, delivered them, and advifed them to expiate the 

 offence by erefting a temple in the New Street to this ima- 

 ginaiy deity. Cicero, de Divin. lib. i. $ 45. Oper. torn. iii.

AJUTAGE, or Adjutage, formed of the verb, ajou- 

 ler, to adapt, in Hydraulics, part of the apparatus of an 

 artificial fountain, or jet d'eau; being a fort of tube, fit- 

 ted to the mouth or aperture of the velTel, through which 

 the v-iater is to be played, and by it determined into any 

 figure and direftion. 



It is chiefly the diverfity in the ajutages, that makes the 

 difierent kinds of fountains. — And hence, by having feveral 

 ajutages to be fupplied occafionally, one fountain comes to 

 have the effect of many. 



Mairiotte inquires into the beft kind of ajutages, or fpoutc, 

 for jets d'caii, affirming, from experiment, that an oen po- 

 lilhed round hole, in the end of the pipe, gives a higher jet 

 than either a cylindrical, or a conical ajutage : of which, 

 however, the latter is the better. Vide Trait, du Movcm. 

 des Eaux, part. iv. Phil. Tranf. N" 181.
