It is further to be borne in mind that the classification now to be described does not in absolute strictness apply to the entire library, but to the acquisitions—comprising, however, nearly four-fifths of the whole—made since Sir Anthony Panizzi's accession to office as keeper of the printed books. The books in Montague House were indeed

scientifically arranged on their removal to the new premises, but space was then wanting to carry out the views entertained by the officer principally entrusted with their arrangement—the late Mr. Thomas Watts, a gentleman of prodigious memory and encyclopædic learning. Mr. Watts subsequently obtained space more in correspondence with the comprehensiveness of his ideas, and the Museum library will bear the impress of his mind for all ages. With his name will be associated that of the late keeper, Mr. Rye, for many years his coadjutor, and whose own independent arrangement of the Grenville library and the reference-library of the reading-room will always be cited as models for the disposition of limited collections. I trust to be excused this brief reference to gentlemen prematurely lost to our profession—the former by death, the latter by indisposition, brought on, it is to be feared, by over-application to his official duties. To the example of the former and the instruction of the latter I am indebted for whatever claim I may have to address you on a subject to which I can contribute little of my own.

The classification of a great library is equivalent to a classification of human knowledge, and may, if men please, become the standard or symbol of conflicting schools of thought. It might, for example, be plausibly maintained that knowledge, and therefore the library, should begin with the definition of man's relation to the unseen powers around him—that is, with Natural Theology. Or with man himself as the unit of all things human

—that is, with Anthropology. Or, on Nature's own pattern, with the most rudimentary forms of existence. Hence, as we heard yesterday from the distinguished gentleman who here represents the fifth part of the world, the reading-room library at Melbourne begins with works on the subject of Sponges. Fortunately for the neutral bibliographer, there exists a book which not only holds in civilised countries a place unique among books, but which has further established its claim to precedence by the practical test of being the first to get itself printed. The Museum classification accordingly begins with the Bible, and I venture to express the opinion that every sound classification will do the same.

When the next question emerges, how to arrange the Bible itself, we alight at once upon a few simple principles, which, with the necessary modifications, will prove applicable throughout. It is obvious that entire Bibles should precede parts of Bibles; that originals should precede translations; the more ancient originals, the more recent; and Bibles in both the original tongues those in one only. We thus obtain the following arrangement at starting: Polyglots, Hebrew Bibles, Greek Bibles. It is equally apparent that Greek cannot be fitly succeeded by any tongue but Latin; that Latin is most naturally followed by its modern derivatives; that these draw after them the other European languages in due order; the Slavonic forming a link with the Oriental, which in their turn usher in the African, American, and Polynesian.

Concordances, consisting of the words of the Bible detached from their context, form a convenient link with Commentaries. The latter fall into two principal sections, according as they relate to Scripture in its entirety or to some particular part. In arranging the former, the erudite labours of scholars are, as far as possible, kept apart from the popular illustrative literature of modern days. The order of commentaries on separate books must, of course, correspond with that of the books themselves in the canon of the Bible.

Next succeeds the very important class of literature representing the Bible in contact with society through the medium of the Church. The most obvious form of this relation is the liturgical. Liturgies accordingly succeed Scripture in the Museum arrangement, precedence being given to the various Churches in the order of their antiquity. A minor but very extensive class of Liturgy, the Psalm and Hymn, naturally follows as an appendix, preceding Private and Family Devotion, which prefaces works on liturgical subjects in general. The next great department of this class of literature ensues in the shape of Creeds and Catechisms. These pass into formal expositions of dogmatic theology, including theological libraries; which lead to the collected works of divines, commencing with the Fathers. The same order is observed here as in the arrangement of the Bible in its various languages: the Greek Fathers leading to the Latin, the Latin to the divines of the nations speaking languages derived from the Latin, and

these to the Teutonic nations, a division practically equivalent to one into Catholic and Protestant. The general theological literature of each nation follows in the same order, excluding works treating of special theological questions, but including all the immense mass of printed material relating to the Reformation and the controversies resulting from it down to the present day. With these the subject of General Theology may be deemed concluded, and we enter not only upon a fresh department, but upon a fresh numeration. The book-presses embracing the subjects hitherto described all bear numbers commencing with 3000. With the new department 4000 commences, and the same remark, mutatis mutandis, is applicable to every succeeding principal division. I must pass very lightly over the numerous sections of this second section. Beginning with the fundamental questions of the being of a God and the truth of Christianity, it embraces every special question which has formed the subject of discussion among Christians, in the order which commended itself as most logical to the original designer of the arrangement. These controversies conduct to the common ground of Religious Devotion and Contemplation, including the important departments of Tracts and Religious Fiction; and these to devotion in its hortatory form—i.e., Sermons, classified on the same linguistic principle as Scripture, and divided into the great sections of collected discourses and separate sermons. With these the subject of specifically Christian Theology terminates, and is

succeeded by the great and growing department of Mythology and non-Christian Religion. Judaism follows, leading by an easy transition to Church History. A few words on the arrangement of this section will save much repetition, as the principle here exemplified is never departed from. It demonstrates the advantage of beginning with a subject like the Bible, respecting the correct arrangement of which there can be no dispute, and which serves as a norm for all the rest. As the Bible necessarily commenced with Polyglots, so Church History begins with General Church History; the various nations succeed in their linguistic, which is practically also their geographical order, provision being, of course, made for the intercalation of sub-sections where necessary, as for instance one on English Nonconformity. Polynesia, as the last member of this arrangement, naturally introduces the next subject—Missions—which in turn brings on Religious Orders, including Freemasonry. Religious Biography follows, arranged on the same principle as Religious History, which is always carried out wherever practicable. Finally, the whole class is concluded by the small but important division of Religious Bibliography.
