RHEUMATISM 189 



Brooders so constructed as to supply the heat from 

 the bottom are very apt to cause rheumatism in the 

 chicks; keeping chicks in damp basements, or per- 

 mitting them to run on cold cement floors, is another 

 cause. ' Chicks are very liable to succumb to this dis- 

 ease, whereas there is less danger of losing the grown 

 fowls unless the disease should go to the heart.
