Silicosis and all other lung troubles classified under the ore general term "pneumoconiosis" have, no doubt, always articled those who were at ail active ia factories, in streets, or on farms. Science and science methods have disclosed these lung troubles. An accumulation of data acd case histories has made more evident the causes and results. With increasing facilities and the acquisition of authentic scientifically exact observations there has been on the part of plant managers a growing sense of responsi bility and the need for protective devices for their em ployees.

It behooves every ceramic manufacturer to prepare a defense against silicosis damage suits. The plant must be as free freo fine air floating dust as is possible and the men must be warned and provided with dust masks. But these precautions are not sufficient, The plant managers must i* prepared to show medical and Xray records. As further evidence` of the seriousness with which the scientists have studied the matter of silicosis the following ooe hundred and thirty-five references are given from a report by H. K. Pancoast and S. P. Pendergrass.* Con cerning there references the authors make the foliowing sir tar.es t: *nre references we have been obliged to consult wrxe very numerous. The literature during the past few years has been replete with articles dealing with the various phases of dust iohalation. We ere obliged to restrict our Ktt of references to those articles which present particular points of interest to the roentgenologist. We have been obliged :o omit many of the references included in our previous presentations. Refereeces E. Arnould. Is anthracosis a disease entity' Presse med,, 37, 1624-26 (1929). C. Basham.

Holmes I should like to call attention to the background of these dedication ceremonies which our friends have made pos sible for us to arrange for today. The New York State College of Ceramics, recently de wed to that status from the status of school, is tb* only institution ;n N'ew York devoted to higher education in cer'imrrs. f-jr ch<f curr-nf year hi canAlmcni is 247, ihis figure representing n 40% increase over that of the preceding year. There is a staff of twelve instructors, each a specialist in his line of work. The College is qp> ganized on the basis of three departments, that of General Technology and Engineering, Claas Technology, and Ce ramic Art. The courses of study embrace ail fields of the ceramic industries in their three essential aspects of tech nology, engineering, and art. The school now consists of three buildings including the cew one to be dedicated, to day, and affords 4(S.OGO square feet of* door space tfevocerf to lecture rooms and laboratories.
