NOTES ON SO-CALLED SLOW FEVER. 
By Herbert S. Adams, V.S., Centreville, Md. 
Malarial Fever , or Miasmatic Poisoning .—This is a disease I 
have learned very little about except by actual observation, 
since my residence here, on Easternshore, Maryland. The only 
article I have seen in print on this subject is the third report of

animals seldom, if ever, have the disease. Farmers who keep 
their stock in poor condition are the ones who have this 
trouble, if the conditions are favorable to it. They are as

these drain ditches, etc., are all full of water, and the grass growing 
in them is covered to a great extent by water and when dry 
weather comes on it is dried up leaving the grasses covered
