A very detailed set of instructions how to cater for a large abbey is to be found in a Barking document called the _Charthe longynge to the office of the Celeresse of the Monasterye of Barkinge_[361]. (8) The _Kitcheness_ superintended the kitchen, under the direction of the cellaress. (9) The _Infirmaress_ had charge of the sick in the infirmary; the author of the _Additions to the Rules_ of Syon, a person of all too vivid imagination, charges her often to chaunge ther beddes and clothes, geue them medycynes, ley to ther plastres and mynyster to them mete and drynke, fyre and water and al other necessaryes, nyghte and day, as nede requyrethe, after counsel of the phisicians, ... not squames to wasche them, and wype them, nor auoyde them, not angry nor hasty, or unpacient thof one haue the vomet, another the fluxe, another the frensy, which nowe syngethe, now wel apayde, ffor ther be some sekenesses vexynge the seke so gretly and prouokynge them to ire, that the mater drawen up to the brayne alyenthe the mendes[362].

Every well organised nunnery therefore divided up its revenues, allocating so much to the church, so much to clothing, so much to food, etc. Rules for the disposition of the income of a house were sometimes drawn up by a more than usually thrifty treasuress for the guidance of her successors, and kept in the register or chartulary of the nunnery. The Register of Crabhouse Priory contains one such document written (in the oddest French of Stratford-atte-Bowe) during the second half of the fourteenth century:
