Machinery for Refrigeration

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. Among the many marvelous strides which the nineteenth century has witnessed in connection with the arts and sciences, those which have been made in the commercial pro duction of cold hold a very important place. The evolution of artificial refrigeration from the theoretical and experi mental to the practical stage hardly dates back forty years, and its present vast proportions have only been approached dur ing the last quarter of the century. The production of ice was probably the chief incentive to the work of the early inventors, but there can be no doubt that the preservation and transportation of food products, and the requirements of industries connected with cold storage, are largely respon sible for the remarkable development of artificial refrigera tion in later days.
