Unfortunately a major portion of the Books, particularly of the foreign ones, did not actually come into the hands of the Author, so that he was forced often to content himself with merely citing the Titles; and in such as are more precisely designated, he omits, as indeed is the case also with _Girtanner_, to give the length (pagination, or number of sheets) of the Works, from which at any rate a relative judgement might be made as to their completeness. Then since its publication almost another decade has passed, and the continuation of his Collection is still awaited on the part of the Author; consequently a second edition, carried on so as to cover the latest period, one that has been very prolific in Literary productions, is both necessary and desirable, and in it what is deficient might easily be supplied. Again from earlier Literature many additions might well be made and supplements giving what was overlooked or only cursorily noted by _Girtanner_. However would it not on the whole be more expedient to undertake an entirely new Work dealing with the whole Literature of Venereal Disease, but on other principles than those of _Girtanner_? Indeed for such a task the use of a Library such as Göttingen would be required. It would undoubtedly be of very great utility. _George Rees_, On the primary Symptoms of the lues venerea, _with a critical and chronological account of all the English writers on the subject, from 1735 to 1785_. Lond. 1802. 8vo. Finally we have to mention the Writers on the History of Medicine who have treated more or less fully the History of the Venereal Disease. To this class belong in especial: _J. Freind_, histoire de la médicine, traduit de l’Anglais par Etienne Coulet. Leide 1727. 8. T. III. S. 192-277. (_J. Freind_, “History of Medicine,” translated from the English by Etienne Coulet. Leyden 1727. 8vo. Vol. III. pp. 192-277). Seeks to prove the American origin. _Chr. Godfr. Gruner_, Morborum antiquitates. Vratislav. 1774. gr. 8. S. 69-101. (_Chr. Godfr. Gruner_, “Antiquities of Diseases.” Breslau 1774. large 8vo. pp. 69-101). Decides for the American origin. _Curt. Sprengel_, Versuch einer pragmat. Geschichte der Arzneikunde. 3. Auflage. Halle 1828. Bd. II. S. 521-525. 697-714. Bd. III. S. 204-217. Bd. V. S. 579-594. (_Curt. Sprengel_, “Attempt at a Pragmatic History of Medicine.” 3rd. edition. Halle 1828. Vol. II. pp. 521-525, 697-714. Vol. III. pp. 204-217. Vol. V. pp. 579-594). The Author accepts the Development of Venereal disease from Leprosy. In connection with other Diseases the Venereal is also dealt with in the following Works: _Franc. Raymond_, Histoire de l’éléphantiasis, contenant aussi l’origine du Scorbut, du Feu St. Antoine, de la _Vérole_ etc. Lausanne 1767. 132 S. 8. (_Franc. Raymond_, “History of Elephantiasis, containing also the Origin of Scurvy, St. Anthony’s Fire, Pox, etc.” Lausanne 1767. pp. 132. 8vo.).
