THE SWAMP FEVER OF HORSES.

and they recognize, under other names, more acute diseases 
and those which do not present the symptoms which have 
come to be recognized as characteristic of Swamp Fever. 
Diagnosis is especially difficult in early cases, in which 
definite symptoms are absent. On the other hand, it is 
made easily in advanced cases in which the symptoms are 
well marked. A horse which has a good appetite and a 
"wobbling" gait and is suffering from an irregular fever, 
which is accompanied by weakness, emaciation, anemia, and, 
perhaps, by polyuria and a thrilling " pulse, is said to be 
suffering from Swamp Fever, especially if it be seen in a 
locality where that disease exists. 
Until the specific causes of the diseases concerned are 
definitely recognized it seems useless, from a consideration 
of the clinical manifestations, to discuss whether more than 
one disease may not be included among the conditions 
which are recognized as Swamp Fever, or whether Swamp 
Fever be identical with diseases, such as the European 
Infectious Anemia, in which similar symptoms occur. 
VIII. Treatment. — Many drugs have been used in 
attempts to treat Swamp Fever. None of them has proved 
to be specific for the disease. A symptomatic treatment 
has often been reported to have been of benefit. Good 
food and tonics, such as nux vomica, iron and arsenic, are 
given for the anemia ; the fever has been controlled by 
antipyretics, such as quinine and acetanilid, and by cold 
spongings and cold enemata. Vermifuges and intestinal 
antiseptics, such as salol, have been given to remove harm- 
ful fauna, or flora, from the alimentary tract. Mercury, the 
iodides, and silver salts have also been given ; they have 
been valueless. 
IX. Observations on two Cases of Swamp Fever. — Two 
horses, suffering from Swamp Fever, were sent to us in Janu- 
ary, 1 9 ID, through the kindness of Dr. J. G. Rutherford, 
the Veterinary Director General and Live Stock Commis- 
sioner of the' Department of Agriculture of the Dominion
