But a habit even more subversive of strictly communal life and more liable to lead to disuse of the frater was rapidly spreading at this period. This was the division of a nunnery into _familiae_, or households, which messed together, each _familia_ taking its meals separately from the rest. The common frater was sometimes kept only thrice a week on fish days, sometimes only in Advent and Lent, sometimes (it would seem) never. This meant the separate preparation of meals for each household, a practice which, though uneconomical, was possible, because each nun's food allowance was fixed and could be drawn separately. Moreover, as we shall see hereafter, the growing practice of granting an annual money allowance to each individual, though used for clothes more often than for food, enabled the nuns to buy meat and other delicacies (if not provided by the convent) for themselves. The aristocratic ladies of Polsloe even had their private maids to prepare their meals[992]. This system was evidently well established at a comparatively early date. It is mentioned in Peckham's injunctions in 1279 and in Exeter and York injunctions belonging to the early years of the fourteenth century. To illustrate how it worked, we may analyse the references to _familiae_ in Alnwick's visitations of the diocese of Lincoln (1440-5)[993]. The number of households in a nunnery necessarily differed with the size of the house and it is not always easy to determine the proportion of households to nuns, because internal evidence sometimes shows that all the inmates were not present and enumerated at the visitation. Thus at Elstow the abbess "says that there are five households of nuns kept in the monastery, whereof the first is that of the abbess, who has five nuns with her; the second of the prioress, who has two; the third of the subprioress, who has two; the fourth of the sacrist, who has three; and the fifth of Dame Margaret Aylesbury, who has two"; but only thirteen nuns gave evidence[994]. In this house the frater was kept on certain days of the week, one nun deposing "that on the days whereon they eat together in frater, they eat larded food in the morning and sup on flesh, and they eat capons and other two-footed creatures in frater." At Catesby the prioress deposed that she had four nuns in her _familia_ and that there were three other households in the cloister. At Stixwould there were "five separate and distinct households"; at Nuncoton there were three; at St Michael's Stamford, the prioress and subprioress each had one, but all ate together in the frater on fish-days; at Stainfield the prioress, the cellaress and the nun-sisters each kept a household. At Gokewell and Langley the nuns were said to keep divers households "by two and two" and at Langley the prioress added, "but they do eat in the frater every day"; also she says that she herself has three women who board with her and the subprioress
