KEPORT OF NATIONAL. MUSEUM, 1924 103 



Three models, prepared, for the Life Extension Institute (Inc.), 

 New York City, and the charts, pamphlets, etc., which go with them, 

 stress the necessity of periodic physical examinations in order to 

 detect disease in its incipiency while there is yet time to combat it. A 

 life extension unit is represented, showing the offices in which the 

 history of the case is recorded and the laboratories and clinics where 

 special and general physical examinations are made. Charts tell the 

 story of a complete examination of this kind and illustrate the object 

 sought — an increase of the life span. 



A series of six small models, prepared for the National Organiza-
