"were written in hexameter and pentameter verses, after the manner of Ovid, whom he had in great esteem, preferring him even before the divine Virgil. I have heard him say that he believed Virgil could not have made the Metamorphosis so well as Ovid has concerning which there have been betwixt us several sharp, but not bitter disputes; for herein I confess I differed from him, though we were, as to all other things, generally speaking, of the same mind, as Horace says of his friend Fuscus Aristius and himself:

hac in re scilicet una

Multum dissimiles; ad cætera pene gemelli

Fraternis animis.”

In a very excellent speech which Barrow made to the students of Trinity College on his appointment to the Humanity Lecture,* he fully confirms this statement of Dr. Pope, when he gives the reasons for selecting Ovid as the subject of his lectures :

"Ex omni choro Authorum, quem unà legeremus, segregavi Ovidium. Torvum enim illud et morosum Virgilianæ majestatis reveriti, incertum et intricatum Papiniani tumoris abominati sumus. Et Horatium, sæpè suaviter nequam, dictisque elegantibus et præceptis non raro lasciviæ ac intemperantiæ virus admiscentem, respuimus. Quin et ipsum præterire ausi sumus Ciceronem, subinde dum largo flumine verborum exundat, rebus et sensibus parcum. Quidni igitur Ovidium in manus sumerem? Ovidium dixi, imò potius Genium quendam ingenii ac eloquentiæ in humana

specie ludentem: cujus versiculos nec mortalis aliqua cura finxisse, nec studium expressisse, neque ars concinnâsse, sed vel natura ipsa sponte effudisse, aut divinior quædam Musa dictâsse videatur. Ovidium, lactea ubertate eloquii, facili proprietate verborum, sincera puritate sermonis, sententiarum apposito lepore, utilique acumine, æquali calore, et continuo styli spiritu cuivis conferendum," &c.

After this he concludes with some admirable instructions for themes, and several other species of composition.

- Almost all the worldly goods which Barrow left behind him consisted in his books; but these were so well chosen, that they sold for more than they cost. He published only two sermons in his life-time; the rest, with the greater part of his works, were given to the world by his surviving and sorrowing father, who thus endeavored to perpetuate the benefits conferred on society by his illustrious son. The task of editing these precious remains was committed to Dr. Tillotson, who appears to have exercised his discretion in dividing some of the sermons, and correcting various inaccuracies in others: he has given a concise account of his editorial labors, and of the works themselves, in the preface.* Abraham Hill, Esq. was his coexecutor, and these two friends were empowered to determine on such works as should be published. Having now gone through the principal events recorded in the life of this great man, who died at the early age, of 47, and yet left behind him such a reputation as few persons have been able to acquire in the longest and most active career, I cannot find a more appropriate conclusion to my

In addition to the above there is in the Public Library at Cambridge, a volume in 8vo. marked Dd. xiv. 9. containing Sermons and Fragments. This Ms. came into its present place with the other Mss. and books of Bishop Moore presented by George I. to the University. The following note appears written at the beginning: "Hic Liber, ut ex manu videtur, fuit viri doctissimi Isaaci Barrow." When I compared its writing with undoubted autographs of Barrow, in company with Mr. Lee, Fellow of Trinity College, who has devoted much time and labor to the completion of a catalogue of Barrow's works, in the library of his own college, neither that gentleman nor myself had any doubt but that the writing in question was Barrow's.

The library of Trinity College contains thirteen Ms. Vols. of Barrow's works, published and unpublished, most of the former being in their primitive state, varying from the printed editions, or rough draughts of what afterwards were expanded into Sermons, &c. Among the latter is an extraordinary number of extracts from Demosthenes, Eschines, Plutarch, Cicero, &c., as well as from the Christian fathers; pages of detached sentences for the treatise on the Pope's supremacy, &c.; arguments on several questions in the Divinity Schools; miscellaneous notes, and references to the New Testament, &c. But the most valuable of these volumes is that containing four sermons, in the first page of which is the following note: "Dr. Isaac Barrow's sermons preached in 1676. Preached by him." The hand-writing is very large, and decidedly not that of Barrow.
