Excerpt from Refrigeration, Cold Storage and Ice-Making: A Practical Treatise on the Art and Science of Refrigeration, With Which Is Incorporated "Refrigerating and Ice-Making Machinery" The preservation of comestibles collected during times of plenty, for uses when the sources of supply fail, has been practised by man from the remotest ages and in the most uncivilised regions. Amongst primitive races, in order to avoid famine the preservation of food for use during certain times of the year was absolutely essential, and in civilised countries it is a factor mainly responsible for the maintenance of the balance between the demand and the supply. Probably the most ancient method employed for the preservation of food stuffs is desiccation or drying, and it is an excellent one, meat, for instance, so treated loses none of its nutritive qualities as it undergoes no chemical change. The remaining methods used arc heating and sealing in air-tight packages, treatment by means of chemicals, and refrigeration. The conservation of meat and other food stuffs by the latter method, which is now so extensively used, is that with which the author is here solely concerned. By means of refrigeration or thermal control meat can now lie transported round the world whilst retaining its original freshness. And fish, milk, butter, eggs, and fruits of almost ever}' variety can also be preserved and transported in good condition. In fact, as stated in the Preface to the first edition of this book, refrigeration is a subject of great and daily increasing interest, and the field of usefulness of the art is continually widening. "When the author produced, in 1895, his smaller work entitled " Refrigerating and Ice-Making Machinery," the literature dealing specifically with the subject was of a very limited, and chiefly of a scattered description, but at the present time there are a number of books published, and the periodical literature has also been largely augmented.
