Dr. Hunter states that of several thousand new-born and perfect children which were weighed at the British Hospital, the smallest was about four pounds, and the largest about eleven pounds two ounces; but by far the greater number were from five to eight pounds, avoirdupois. He adds, that he never knew an instance of a child born at the natural period weighing twelve pounds. Of sixty male and sixty female children, born at the full time, which were weighed by Dr. Clarke, the lightest was four pounds, and the heaviest ten pounds. He found that the average weight of the males was seven pounds five ounces and seven drams, avoirdupois; that of the females only six pounds eleven ounces and six drams. The weight therefore of new-born children varies considerably.
