a very sensible "_Universalis in notitiam cujusque generis bonorum Scriptorum Introductio_"--of this work two subsequent editions, one in 1691, the other in 1700, 4to., were published at Helmstadt. The last is the best; but the second, to him who has neither, is also worth purchasing. The seven dissertations "_De Libris legendis_" of BARTHOLIN, Hafniae, 1676, 8vo., are deserving of a good coat and a front row in the bibliographer's cabinet. "Parvae quidem molis liberest, sed in quo quasi constipata sunt utilissima de libris monita et notitiae ad multas disciplinas utiles." So speaks Morhof.] [Footnote 126: ADRIEN BAILLET was the eldest of seven children born in a second marriage. His parents were in moderate circumstances: but Adrien very shortly displaying a love of study and of book-collecting, no means, compatible with their situation, were left untried by his parents to gratify the wishes of so promising a child. From his earliest youth, he had a strong predilection for the church; and as a classical and appropriate education was then easily to be procured in France, he went from school to college, and at seventeen years of age had amassed, in two fair sized volumes, a quantity of extracts from clever works; which, perhaps having Beza's example in his mind, he entitled _Juvenilia_. His masters saw and applauded his diligence; and a rest of only five hours each night, during two years and a half of this youthful period, afforded Baillet such opportunities of acquiring knowledge as rarely fall to the lot of a young man. This habit of short repose had not forsaken him in his riper years: "he considered and treated his body as an insolent enemy, which required constant subjection; he would not suffer it to rest more than five hours each night; he recruited it with only one meal a day--drank no wine--never came near the fire--and walked out but once a week." The consequence of this absurd regime was that Baillet had ulcers in his legs, an erysipelatous affection over his body, and was, in other respects, afflicted as sedentary men usually are, who are glued to their seats from morn till night, never mix in society, and rarely breathe the pure air of heaven. These maladies shortened the days of Baillet; after he had faithfully served the LAMOIGNONS as a librarian of unparalleled diligence and sagacity; leaving behind him a "_Catalogue des Matieres_," in 35 volumes folio. "All the curious used to come and see this catalogue: many bishops and magistrates requested to have either copies or abridgments of it." When Baillet was dragged, by his friend M. Hermant, from his obscure vicarage of Lardieres, to be Lamoignon's librarian, he seems to have been beside himself for joy.--"I want a man
