    Galen always calls this operation Para- kentejis [c], a punffion, as he does the in- ftrument with which it is performed Para- kenteterium, and the operator Parakentetes : which words are at this day appropriated folely to the operation for the dropfy, called in Englijljy tapping. It is obfervable of this antient, that, though he is lingular in the name, he is fo explicit in his defcription of the operation for the Cataradt, that he leaves us no doubt but the dodtrine we (hall advance is agreeable to the pradtice of thofe times [d\. He tells us that the oculift places the needle in a great cavity, wherein it is feen to work above and below, to the right and to the left, and ail manner of ways, without hurting (fays he exprelly) the iris on the one fide, or the chryftalline on the other. The fpecific term in Greek for this ope¬ ration, is Kenembatejis [e], palling through the void, becaufe the needle enters into the, cavity of the eye. Celfus exprefsly explains the word, in the fame chapter where he ahattre le Catarafty or aguilleter le Cataract. The latter may be very properly tranflated, needle the Cat.ara£ly the needle being the only inftrument with which the Ocu¬ lift here operates.
