We illustrated and described this invention on page 161 of the present volume of Scientific Asiekican ; since which we have had one in use, and find it to be exactly the thing for summer use. A very small quantity of charcoal will cook, boil water, or heat irons in a short time, making no dirt-or dust, and there is no suffocating atmosphere such as a range produces in hot weather. We can he'artily recommend it. The manufacturers and dealers are Smith & Burns, 9 Carmine street, New York. We have to thank C. F. Loosey, Esq., Austrian Consul at New York, for six numbers of the Zeitschrift, the journal of the Austrian engineers, published in Vienna.
