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.

 He is put in a sling and shackled, and, 

 when all is ready, the table returns to a

A tilting table operated by an electric motor is used for examining horses and

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.
