Silicosis and all other lung troubles classified under the more general term "pneumoconiosis" have, no doubt, always afflicted those who were at all active in factories, in streets, cr on farms. Science and science methods have disclosed these lung troubles. An accumulation of data and 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 par: of plant managers a growing sense of responsi bility and the need for protective devices for their em ployees. As a reward for these humanitarian disclosures and efforts, the racketeering lawyers and doctors have seen the chance for making easy money. It behooves every ceramic manufacturer to prepare a defense against silicosis damage suits. The plant must be as free from 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 be prepared to show medical and X-ray records. As further evidence1 of the seriousness with which the scientists have studied the matter of silicosis the following one hundred and thirty-five references are given from a report by H. X. Pancoast and E. P. Pendergrass-1 Con cerning these references the authors make the following statement: The references we have been obliged to consult were very numerous. The literature dunng the past few years has been replete with articles dealing with the various phases of dust inhalation. We are obliged to restrict our Hst of references to those articles which present particular points of interest to the roentgenologist. We have been obliged to omit many of the references included in our previous presentations. References E. Arnouu Is anthracosis a disease entity? Presse mid., 37, 1624-26 (1929). C. Badham.

CERAMIC SCHOOL NOTES NEW YORK STATE COLLEGE OF CERAMICS AT ALFRED UNIVERSITY Dedication Erercises for the New Ceramic Building, at Alfred, New York, June 12, 1933 Introductory Remarks by Dean Major E. 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 ele vated .to thac status from the status of a school, is the -...........-- - v?w wvnriH fn higher education this figure representing a 40% increase over thac of the preceding year. There is a staff of twelve instructors, each a specialist in his line of work. The College is or ganized on the basis of three departments, that of General Technology and Engineering, Glass Technology, and Ce ramic Art. The courses of study embrace all 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 new one to be dedicated to day, and affords 40,000 square feet of floor space devoted to lecture rooms and laboratories. New, up-to-date equipment worth 540,000 has been installed in this new building during the past year and 515,000 worth will be installed in the coming year. o BULLETIN OF THE FERRO ASBESTOS MITTS The same high quality . . .
