This is a well known and very frequent condition of the lungs 
of horses affected with malleus, and I cheerfully concede that I 
have met with much difficulty in my endeavors to follow its 
development and to arrive at a satisfactory idea of the same. 
The parts of lungs thus infiltrated appear jelly-like, transparent, 
firmly filled with fluid, and extended to a degree conformable to a
