Mr. D. E. Smith's 'Rara Arithmetica,' a catalogue of arithmetical works which appeared prior to the year 1601, was printed, in a limited edition, at Boston (United States) in 1908. It is a sumptuously produced work in two large octavo volumes, copiously illustrated. Professor de Morgan's 'Arithmetical Books from the Invention of Printing to the Present Time' contains brief notices of a large number of works 'drawn up from actual inspection.' It was published—a thin octavo of 124 pages—in 1847, and the books are arranged chronologically; but there is an index of authors.

Medical.

37. The collection of early medical books is a hobby that must appeal chiefly to the chirurgeon. Its sub-headings are not numerous, and each comprises volumes of considerable bibliographical interest. There are curious books on 'poysons' as well as upon the commoner branches of surgery, and there are glorious editions of all the ancient Æsculapians, such as Hippocrates, Dioscorides, Galen, and Avicenna. Herbals are doubtless collected by many who are not possessed of medical knowledge, and a number of them treat more of simples and housewifery than leechcraft, which is probably one reason of their attraction for the non-medical collector. But as these volumes in general are so inextricably bound up with the science of healing, I have thought fit to include them here. There is no denying that the fascination of these curious volumes, often (as in Fuch's magnificent tome) containing woodcuts that are a sheer delight to the bibliographer no less than to the botanist, is a strong one.

It is a moot point whether works on Early Chemistry or Alchemy should be included here or under the heading 'Occult,' seeing that they usually centre about the Elixir of Life and the Philosopher's Stone. Perhaps they would be classed more accurately with Early Scientific. But for the purposes of our list I have reserved that heading for those books which treat of mathematics and physics only. With the early works upon astrology we need not concern ourselves here: they have more to do with divination and horoscopes than the craft of healing, so their appeal is chiefly to the student of the occult. It is impossible, however, to classify under one heading all those early works which treat of the beginnings of scientific knowledge. The star-gazer, the herbalist, the necromancer, and the leech, must be content to share among themselves a class of books which deals generally with the search into the Great Unknown.

A useful catalogue of books on Alchemy was printed in two large quarto volumes at Glasgow in 1906. It is by Professor John Ferguson, and is entitled 'Bibliotheca Chemica,' being a list of the hermetic books in the library of Mr. James Young. The three volumes entitled 'Leechdoms, Wortcunning, and Starcraft of Early England' by the Rev. Oswald Cockayne, published in the 'Rolls' series, 1864-66, contain a valuable contribution to the early medical science of this country. Dr. J. F. Payne's 'English Medicine in the Anglo-Saxon Times' (the Fitz-Patrick Lectures for 1903) is for the most part a dissertation on that work.

Some of the prescriptions of these early leeches are rather quaint. 'If a man's head burst . . . let him take roots of this same wort, and bind them on his neck. Then cometh to him good benefit.' The following is an excellent remedy for toothache: 'Sing this for toothache after the sun hath gone down—"Caio Laio quaque voaque ofer saeloficia sleah manna wyrm." Then name the man and his father, then say: "Lilimenne, it acheth beyond everything; when it lieth low it cooleth; when on earth it burneth hottest; finit. Amen."' If after this the tooth still continues to ache beyond everything, it is evident that there is a wyrm in it. For stomach-ache, you must press the left thumb upon the stomach and say 'Adam bedam alam betar alam botum.' This is infallible.

Collections of medical authors began at an early date. Van der Linden's 'De Scriptis Medicis, libri duo' appeared first at Amsterdam in 1637, octavo—a valuable list of authors and the editions of their works. But it was reprinted with additions several times during the author's lifetime (he died in 1664); and in 1686 appeared at Nürnberg as a thick quarto entitled 'Lindenius Renovatus.' Dr. E. T. Withington's 'Medical History from the Earliest Times,' octavo, 1894, is useful for reference; whilst Dr. Norman Moore has recently produced (Oxford, 1908) a 'History of the Study of Medicine in the British Isles.' Dr. E. J. Waring's 'Bibliotheca Therapeutica' was published in two octavo volumes by the New Sydenham Society in 1878-79. It is a list of the books which have been written on each individual drug, classes of medicines, and general therapeutics. There is an index of authors. The first volume of Albrecht von Haller's 'Bibliotheca Anatomica' was published at London 'in vico vulgo dicto The Strand' in 1774; the second volume at Zurich in 1777. Both are in quarto, and are biographical as well as bibliographical. The same author published a 'Bibliotheca Chirurgica' and a 'Bibliotheca Medicinae Practicae' at Berne and Basel between 1774 and 1788. His 'Bibliotheca Botanica,' two quarto volumes, appeared at Zurich in 1771-72. For other writers upon Botany you must consult Curtius Sprengel's 'Historia Rei Herbariae,' two octavo volumes which appeared at Amsterdam in 1807 and 1808. 'A Guide to the Literature of Botany' by B. D. Jackson was issued by the Index Society in 1881. Jean Jacques Manget, a Geneva physician who died in 1742 at the age of ninety-one, was another voluminous compiler of bibliographies upon medical subjects.

Military.

38. Under the heading 'Military' are included not only historical accounts of military operations but those works which treat of the military art and the progress of its development. Obviously it is a subject that is as old as mankind, and dissertations on drill with the stone battle-axe must find a place here. Many of the books on Arms and Armour (such as Sir Samuel Meyrick's beautiful folio volumes) are fine works, and some of the earlier publications on Castramentation and Siege operations are interesting. We must not forget to mention the beautiful little Elzevier 'Cæsar' of 1536. It is a wide heading, for such books as the Commentaries of Blaise de Montluc and the Memoirs of Olivier de la Marche must be included, as they deal in large part with military operations. Books on Archery, Fencing, and Duelling are also comprised by this heading.

If this be your subject, our book-hunter trusts that you have been more successful than he has in your quest for the 'Traicté de l'Espée Françoise, par Maistre Jean Savaron' (small octavo, Paris, 1610). He narrowly missed a copy in Paris some years ago, and so far this scarce little volume of fifty-six pages has eluded him as successfully as the 'Pastissier François.' Probably, on account of its slimness, it is usually bound up with more substantial works, and thus escapes the eyes of book-hunters and cataloguers. Savaron also wrote a 'Traicté contre les Duels,' which is equally scarce. Works on duelling are legion, and range from Carafa's rather large folio entitled 'De Monomachia seu de Duello,' Rome, 1647, down to the little 'Dissertation Historique sur les Duels et les Ordres de Chevalerie: Par Monsieur B * * * *,' which is by Master Jacques Basnage—a duodecimo produced first at Amsterdam in 1720. An Italian bibliography of this subject by J. Gelli and G. E. Levi appeared in 1903. For the most part they are uncommon works and not easy to find. It is a subject that borders closely on the Chivalry of our list, for of course that subject was (like Heraldry) entirely military in origin. A 'Bibliography of English Military Books up to 1642, and of Contemporary Foreign Works' was compiled by Captain M. J. D. Cockle and published in quarto in 1900. Mr. Carl Thimm's 'Art of Fence: a Complete Bibliography' appeared in 1891; an enlarged edition was put forth in 1896.
