These discourses, though written in Cornaro's old age, were penned at different times, and published separately: The first, which he wrote at the age of eighty-three, is intitled, A Treatise on a Sober Life, in which he declares war against every kind of intemperance; and his vigorous old age speaks in favour of his precepts. The second treatise he composed at the age of eighty-six: it contains farther encomiums on sobriety, and points out the means of mending a bad constitution. He says, that he came into the world with a choleric disposition, but that his temperate way of life had enabled him to subdue it. The third, which he wrote at the age of ninety-one, is intitled, An Earnest Exhortation to a Sober Life; here he uses the strongest arguments to persuade mankind to embrace a temperate life, as the means of attaining a healthy and vigorous old age. The fourth and last, is a letter to Barbaro, Patriarch of Aquileia, written at the age of ninety-five; it contains a lively description of the healthy, vigour, and perfect use of all his faculties, which he had the happiness of enjoying at that advanced period of life. This useful work was translated some years ago into English, under the title of _Sure and certain methods of attaining a long and healthy life_. The translator seems rather to have made use of a French version than of the Italian original; he has likewise omitted several passages of the Italian, and the whole is rather a paraphrase than a translation. This has induced us to give the public an exact and faithful version of that excellent performance, from the Venice edition in 8vo, in the year 1620 [1]: and as a proof of the merit and authenticity of the work, we beg leave to quote Mr. Addison's recommendation of it, SPECTATOR, Vol. iii, No 195.
