calculated every adult peasant to eat two pounds a day. And he added, without having received any leading question from me, of in any degree knowing my opinion upon the subject, that if the peasantry of his country would substitute (which they could do) a small quantity of animal food, with potatoes, instead of so much bread, they would live much longer, and with much better health. I am inclined to pay much deference to M. Dutrochet's opinion; for he combines the advantages of a regular medical education with great acuteness of mind, and I believe him to be as well acquainted with the general laws of organic life as any person living: and I think his opinion deserves some support, from the well known fact, that the duration of human life has been much greater in England during the last sixty years, than in the preceding period of the same duration. Bread made of wheat, when taken in large quantities, has probably, more than any other article of food in use in this country, the effect of overloading the alimentary canal: and the general practice of the French physician points out the prevalence of diseases thence arising amongst their patients. I do not, however, think, or mean to say, that potatoes alone are proper food for any human being: but I feel confident, that four ounces of meat, with as large quantity of good potatoes as would wholly take away the sensation of hunger, would afford, during twenty-four hours, more efficient nutriment than could be derived from bread in any quantity, and might be obtained at much less expense."--_Trans.

The Caliph Haroun al Raschid is stated to have maintained an unbroken friendship with his contemporary Charlemagne, throughout their mutual reign. A variety of magnificent presents attested the esteem of the caliph for his Christian friend. Among them were several objects, which tend to show the advance which art had made, at this time in the East. The first of these was a clock of gilded bronze, round which the course of the twelve hours was displayed; while, at the end of each hour, the number of brazen balls which were requisite to mark the division of time, were thrown out from above, and falling consecutively on a cymbal below, struck the hour required. In like manner a number of horsemen issued forth from windows placed around the dial; while a number of other clock-work miracles attested the height which the mechanical arts had reached at the court of Haroun.
