Thc name of Mr. Thomas D. West, of Cleveland, Ohio, has long been familiar to foundrymen on both sides of the Atlantic as an authority 'on foundry practice, and op the peculiarities of cast iron in particular. Mr. West is at present engaged in an inquiry as to the real cause of the globules which occur in gas cavities, of the solidly encased shot iron observed in other cases, ami of hard streaks of white iron which are at times found inside of grey and soft iron. But little is yet known as to how these mischances arise, nor as to the best methods of avoiding them. Mr. West is accordingly collecting and studying samples of the defects enumerated, and is anxious to secure specimens from British as well as American sources. He is, therefore, making an appeal to foundrymen in this country to send him interesting samples of the defects enumerated, together with as full data as piacticable as to the conditions in which they made their appearance. . The character of the pig iron and of the scrap should be stated, also that of the fuel and flux, as well as particulars of anything unusual occurring during the heat. If possible, an analysis of the casting should be added, but in any case the specimen should bo accompanied by a statement as to the grade of casting produced, whether medium, soft, or hard. A rough sketch of the casting, having marked on it the location of the sample, would, Mr. West says, prove valuable, as would also particulars as to the character of the mould, and of the methods adopted for gating and pouring. To these data should be added a statement as to the conditions m which the metal was tapped, and in which it was poured, whether hot, medium, or dull. Mr. West intends to make the results of his inquiry the subject of a paper to be read before a leading technical society. His address is 10,511 Pasadena Avenue. Cleveland, Ohio.
