In questioning a MS. for any of these indications (except the last) you must be on the look-out for signs of erasures, especially on the margins of the first leaf and on the fly-leaves at either end. Here the owner's name was usually written. Often it was accompanied by a curse on the wrongful possessor, and at the Dissolution there were many wrongful possessors, who, whether disliking the curse or anticipating trouble from possible buyers, thought it well to erase name, and curse, and all. They seldom did it so thoroughly that the surface of the vellum does not betray where it was, and it can be revived by the dabbing (_not_ painting) upon it of ammonium bisulphide, which, unlike the old-fashioned galls, does not stain the page. Dabbed on the surface with a soft paint-brush, and dried off at once with clean blotting paper, it makes the old record leap to light, sometimes with astonishing clearness, sometimes slowly, so that the letters cannot be read till next day. It is not always successful; it is of no use to apply it to writing in red, and its smell is overpowering, but it is the elixir of palæographers. Yet, when all has been done, there is a sadly large percentage of MSS. which preserve an obstinate silence. They have been rebound (that is common), and have lost their fly-leaves in the process, or, worse than that, they have lain tossing about without a binding and their first and last quires have dropped away. In such cases we can only tell, from our previous experience in ancient handwritings, the date and country of their origin. ENGLISH LIBRARIES And now to turn to some individual libraries. Some of the most venerable have practically disappeared--that of Glastonbury, for instance, the premier abbey of England, the only one which lived through from British to Saxon times.[C] To it we might reasonably look to trace many an ancient book belonging to the days of the old British Church. Leland, who visited the library not long before the Dissolution, represents himself as overawed by its antiquity. But almost the only record he quotes is one by "Melkinus," which most modern writers think was a late forgery. However, there is in the Bodleian one British book from Glastonbury, written, at least in part, in Cornwall, and preserving remnants of the learning of the British clergy. It has portions of Ovid and of Latin grammar, and passages of the Bible in Greek and Latin. The catalogue, too, shows that there were in fact a good number of old MSS., and also that the monks of the fourteenth century did not care much about them, for they are marked as "Old and useless," "Old and in bad condition" (_debilis_), and so on. The actual extant books which we can trace to this foundation are few and for the most part late.
