 for many settings of eggs ; and there the case rests, as

 make nothing of it, and it was not the fungus called 

 Saprolegnia. There was merely a cancer-like sore 

 with broken-down tissue which flowed out of the sores 

 in a pinkish fluid, and that was all. 



After a careful investigation I found that some beef
