In a cylindrical retort of refracting clay, used for the distillation of coal-gas, was placed the body of an unfortunate poodle dog, drowned for contravention of the muzzle laws promulgated by the police. The dog weighed twenty-two and a half pounds. The apparatus was heated by a crown of flames issuing from a perforated circular tube. In order to render combustion as active as possible, the coal-gas was mixed with a certain quantity of pure air. Our readers will recollect this addition of atmospheric air is the principle of the Bunsen burner, which ensures perfect combustion of coal-gas, and produces a maximum of heat with a minimum of light. The cremation lasted several hours, producing a thick smoke, &c. After carbonisation, the skilful chemist succeeded in obtaining complete incineration, that is to say, the calcination of all the solid parts of the body, which weighed one pound fourteen-and-a-half ounces. Satisfied with the result of this experiment, which proved the possibility of reducing the carcase of an animal to ashes by ordinary coal-gas, Dr. Polli proceeded with a second and more complete experiment. One improvement was the disposition of a vertical retort in such manner as to consume the gaseous products of combustion. This is easily effected by placing at the upper orifice of the retort a second ring of gas jets. On this occasion better arrangements were made for carrying out the principle of the Bunsen burner, with the result of producing the complete incineration of a dog weighing forty-two and three-quarter pounds in the space of a couple of hours. On this occasion the solid residue weighed only two pounds and some ounces.
