^{page 299 note a} These wells ov fontes seem to have served as settling tanks before the water reached the head conduit.

^{page 301 note a} A suspiral was no doubt in the first place a vent or breathing-hole (spiramen or spiraculum) to let the air out of a conduit, to avoid a supposed danger of the pipes being burst by the compression of the air within; and in that sense the Promptorium Parvulorum has “Suspyral, of a cundyte. Spiraculum vel Suspiraculum.” (At Durham the word was shortened to “susper.”) But in the drawing under notice the suspirals seem to have served the further purpose of settling tanks, and as a means of relieving the pipes from the pressure of the water. This must have been considerable, there being a fall of about 64 feet from the White Conduit to the distributing cistern in the great cloister of the Charterhouse, a distance of almost exactly a mile.

^{page 302 note a} “Wind vent” here seems to be applied to what in other places would be called a snspiral. See note on preceding page.

^{page 305 note a} The course of the St. John's pipe remains in outline as far as the lower edge of the membrane, with traces of a suspiral above. The course of the nuns' pipe may be similarly traced. But in tinting the drawing the limner has discontinued the nuns' conduit before reaching the crossing of the pipes, and roughly daubed in th e St. John's pipe as following the same direction as the other.

^{page 308 note c} The word “age,” meaning apparently the distributing cistern of a conduit, seems to be identical with the Latin augea, a word used in grants relating to the water-supply of London in the fifteenth century. Thus the Abbot and Convent of Westminster in March 1439-40 granted to the Mayor and Commonalty “unum capud simul cum quibusdam fontibus…una cum augeis sesperalibus fontibus et cisternis congruis ac convenientibus ad includendam recipiendam. et habendam aquam salientem ac emanentem in quodam clauso nostro vocato Oxlese infra terram et precinctum Manerii nostri de Padyngton…erigere construere ponere et habere valeant imperpetuum” (Patent Roll, 21 Henry VI. pt. 2, m. 2). Another grant to the Major and Citizens by the King in June 1443 refers to the building of “quandam Crucem spectabilem in Westchepe dicte civitatis pro quadam augea eisdem conductibus tanquarn mater deservitura” (Ibid. m. 14).

The former of these quotations occurs in an inspeximus of Henry VI., dated 24th June, 1443, printed in Rymer's Fædera (xi. 29-33), on whose authority Du Cange has the following: “Augea Ventosa, Spiramentum, Gall. Ventouse. Dicitur de canalibus fontium, quibus parvum additur foramen, quo interclusi venti elabantur, a Gallico Auge, Alveus, canalis: Augece Ventosæ, suspirales fistulæ, pipæ et aliæ; machinæ, per quas tota aqua, veniens et discedens a capitibus et fontibut prædictis, recipitur et currit…dictas Augeas Ventosas, suspirales fistulas, pipas et alias machinns… perscrutari, mundari et reparari, apud Rymer, torn. 11, pag. 29.” [Glossarium Mediæ et Infimce Latinitatis (Niort, 1883), i. 476,Google Scholar s.v.] In the text as entered on the Patent Roll there is no such punctuation as has misled Du Cange, the words reading: “nonnulle augee ventose suspirales fistule pipe et alie machine,” etc.

Crabb's, Universal Technological Dictionary (London, 1823)Google Scholar gives: “Augea (Archæol.) a cistern for water.”

^{page 309 note a} At Mount Grace, where the arrangement of the pipes must have been similar, every monk had a tap fixed, in a small arched recess in the wall on the cloister side of his garden, usually under a penntise.

^{page 310 note a} A small tank has lately been uncovered in one of the gardens at Mount Grace.

^{page 312 note a} It stood on the site of a row of houses in the parish of Holy Trinity, Islington, on the south side of the street now (1902) called Denmark Road, but formerly White Conduit Street. See the map, engraved in 1841, in The History and Topography of the parish of St. Mary, Islington, by Lewis, S., junior (Islington, 1842),Google Scholar where the “White Conduit House” itself is shown. It had, however, been destroyed in 1831 (op. cit. 396).
