the catalogue to be perhaps the largest collection of heads ever exposed to sale,' We are also informed that it was thought proper, for the accommodation of the curious, to separate the volumes.' Thus was the collection dispersed, never again to be united-to the irreparable loss of the learned and ingenious!

5. Philosophy, Chemistry, Medicine, &c. UNDER this head, comprehending anatomy, astronomy, mathematics, and alchemy, there appear to have been not fewer than 2500 volumes in the foreign languages, and about 600 in the English: some of them of the most curious kind, and of the rarest occurence.

6. Geography, Chronology, and General History.

THERE were about 290 volumes on these subjects, written in the Latin, French, Italian and Spanish, languages, and about 300 volumes in our own language. Some of the scarcest books printed by Caxton were among the latter.

7. Voyages and histories relating to the East and West Indies.

About 800 volumes:-nearly equally divided into the English and foreign languages. Among the English, were Caxton's Recuyell of the historys of Troye,' 1471 (supposed to be the first book printed in this country ;) and his Siege and conquest of Jherusalem,' 1481.

8. Civil, Canon, and Statute Law.

AT least 800 volumes: 300 in the foreign languages, and the remaining in English.

9. Books of Sculpture, Architecture, &c. Nor fewer than 900 volumes, comprehending every thing published up to that period which was valuable or rare. Of these, more than 700 were written in Latin, Italian, French, or Spanish-and embellished with every beauty of graphic illustration.

IN his fifth lecture on the Chemical Phenomena of Nature, Mr. Davy considered the mechanical excitation of heat as produced by percussion, friction, and collision. Some experiments were exhibited on the production of heat by the condensation of air, and it was shewn that certain inflammable bodies are capable of being inflamed by it. Some singular facts were stated with regard to the chemical agencies of light. It would appear, from different experiments, that invisible rays exist in the solar beam possessed of chemical powers; but neither of illuminating nor heatmaking agencies.

J. Northcote.

Mr. Northcote has painted this series of pictures in imitation of Hogarth's

Idle Apprentice: and as far as colouring is concerned, has succeeded in the undertaking. An air of sweetness and simplicity pervades the good servant, of impudence and artifice the bad one.

No. 59. The good girl in her chamber, at her devotions,' is perhaps the best picture of the series. When the pencil is employed on such subjects, the connoisseur readily assents to the sacrifice of the higher departments of the art, in consideration of the extensive good which such representations seldom fail to produce. One immoral character converted, is worth a thousand rapturous exclamations of the knowing!

These pictures have all been engraved.

PETIMUS BENE VIVERE.

WE SEEK TO LIVE WELL.

HOR.

AMONG a variety of letters on good living, I have received two which I offer to the perusal of the reader. The first, which came to hand above a month ago, has the merit of extreme fashion, without being liable to any objection on the score of self gratification. The second may be found to have rather too much of the epicurean philosophy in it.
