Using the X-Ray on Animals

A laboratory for finding out what ails injured horses, cows, cats, dogs, and birds

��WHILE medical annals have been recording the marvelous work of the X-Ray in saving human life, and volumes have been written of the work of the great experimenters, a New York doctor has been carry- ing this saving Hght of science into another field — that of our four-footed neighbors.

��Hospital and X-Ray Laboratory, for the treatment of horses, dogs, cats, birds, and all kinds of pets, is the only one, so far as known, in the world. Certain experi- mental work along this line has been done in the University of Colorado, but Dr. Griessman is the only man to organ- ize an institution for carrying on prac- tical work.

He has i)ersonally diagnosed under the X-Ra\' hundreds of cases of bone diseases, fractures, dislocations, heart enlarge- ments and tubercular conditions, of various tissues and organs. His subjects have been horses, dogs, cows, cats, chickens, canaries and nionkeys. His laboratories are e(|iiippi'd for handling all kinds of animals.

I'or horses and cows he has constructcil a tilting t.ible operated by an eiectri-

��of pullcNs and wires so that it can be convenit'iitK- swimg to any point. In- muuerable dit'licullies encoiuitered in handling the service in Dr. Griessman's Hospital were overcome by Mr. Frank V. McGirr, a young electrical engineer.

��Coal-Mine Fatalities in the United States During 1915

Tl liCRL has been a gratif\ing decrease in the number of fatalities occurring in coal mines in the United Slates dur- ing 1915. The number reported during the year was 2,264, =>!^ compareil with 2,434 in 1914, and 2,785 in ii)i,V The actual mimber killed during li)',S was the lowest for any year since 1906, when there were 2,138 fatalities.
