Note 1 — AUTHOR’S PREFACE TO THE FIRST (GERMAN) EDITION.

It would be a great mistake to think that because SPRENGEL wrote his History here, the opposite must be true. The greater part of the Works collected by him are no longer to be found. It is only too evident that the earlier administrators of the library, especially ERSCH, so famous as a Historian of Literature, left the medical side almost totally unconsidered; and what gaps the Administration of to-day has to fill up is sufficiently evidenced by the yearly Lists of Additions.
