In framing these tables I have included among the Libri cathenati those specially presented to the College, 46 in number; but I have not attempted to sort them according to subject. I have also assumed that any book or books representing a given class, if not represented in the lending library, as Astronomy, Arithmetic, Music, etc., would be chained for reference. The number of this class, 220, if added to the 160 of the other class, gives the required total, 380.
In addition to these tables it will be interesting to construct a third, containing the subject and number of the books represented in both collections:

The subjects of the books included in this latter table represent, in a very clear and interesting way, the studies pursued at Peterhouse in the 14th and 15th centuries. It is prescribed by the statutes, dated 1344, that the scholars are to study Arts, Aristotelian Philosophy, or Theology; but that they are to apply themselves to the course in Arts until, in the judgment of the Master and Fellows, or at least of the larger and wiser portion of that body, they are sufficiently instructed to proceed to the study of Theology[300]. Two may study Civil Law or Canon Law, but no more at the same time; and one may study Medicine[301]. For both these lines of study special leave is required.
The course of Arts comprised Grammar, Logic, Aristotle, Arithmetic, Music, Geometry, and Astronomy. In the first of these, including Poetry, the lending library contained more volumes than the reference library; in Logic it had three times as many; in Philosophy (Aristotle and his commentators) it was well supplied; but, on the other hand, Music, Geometry and Astronomy were wholly wanting. Theology is represented by 63 volumes as against 61 in the reference library; Civil Law by 20 volumes against 9 in the reference library; and Canon Law by 19 against 18. In Medicine, however, there were only 3 against 15. By a curious coincidence the number of volumes in the two collections dealing with the subjects represented in both is the same. The subject most in request, as might have been expected, was Theology. Next to this come Civil Law and Canon Law. Medicine was evidently unpopular. I have no explanation to offer for the curious fact that Arithmetic, Music, Geometry, and Rhetoric are represented by only a single volume apiece in the library of reference[302].
These examples, which there is no reason to regard as exceptional, are sufficient to shew that an ordinary chamber would be large enough to contain all the volumes possessed by a college, even after some of the more generally useful books of reference had been chained to desks for the resort of students.
It has been already shewn that what Professor Willis calls "a real library—that is to say, a room expressly contrived for the purpose of containing books[303]"—was not introduced into the plan of colleges for more than a century after their first foundation. He points out that such rooms can be at once recognised by their equidistant windows, which do not, as a rule, differ from those of the ordinary chambers, except that they are separated by much smaller intervals. Examples of this arrangement are still to be seen at S. John's College, Jesus College, and Queens' College, Cambridge; but perhaps the most characteristic specimen of all is that which was built over the Hall at Pembroke College in the same University, by Laurence Booth (Master 1450-1480), the aspect of which has been preserved in Loggan's print, here reproduced ([fig. 48])[304].
