War. Diaurauis illustrate the relative deadliness of disease 

 geruis and bullets in earlier wars; and their lesson is reinforced by 

 a re]:)resentati(m of the relative importance from injuries in action and 

 from typhoid fever during the Spanish War. (Jne company, con- 

 fronted by a cannon, suffers the loss of one man wounded, while the 

 other, facing a tube of typhoid germs, has one dead and thirteen in the 

 hospital. Other models show liow camp wastes are disposed of, and liow 

 water supply is sterilized, and still others, how the soldier's tent is pro- 

 tected against mosquitoes and how a field hospital is equipped. The 

 field ration of the soldier and the preparation of anti-typhoid vaccine 

 are illustrated by specimens and models. 



Two tree trunks, one normal and the other infested with fungi as a 



result of mechanical injury, illustrate the important fact

his granddaughters, Maria R. and Florence Audubon, 



occupies the stairway hall. It includes original sketches and paintings 



by Audubon and his sons, illustrations in various stages from the Quad- 



ru]XHls of North America, and some of the copper plates of the ''Birds of 



North America." The most important piece is a large painting of a 



covey of "English" pheasants, flushed by a dog. Of more personal 



interest is the gun carried by Audubon on many of his ex]3editions and 



a favorite buckskin hunting coat.
