Mix, and give this dose two or three times a day. When only one 
lung is involved, recovery occasionally takes place ; when both are in- 
volved, there is little or no hope. For cough and debility during con- 
valescence, he advises the following tonic : 
21. % Oz. oxide of magnesia, 
• ^ a Oz. iron filings, fine, 
In Oz. tincture of gentiaa, 
1 Pt. water. 
To be given daily. 
Another prescription is recommended — 
No. 23. .1 Drachm carbolic acid, 
1 Pint water. 
To be given as a dose three times a day. 
The reader will see, upon a careful study of the foregoing, that but 
one prescription — killing — is the only safe plan. 
Texas Fever. 
This disease, now called Splenic Fever, resembles in some of its phases 
the terrible Rinderpest of Asiatic Russia, but it is far less malignant and 
less contagious. It also disappears with the first frost, being effectually 
stamped out during the Winter, not to be again seen until again reintro-

Northern cattle to other beasts. The disease has its home on the coast 
of Texas, but how it originated is not clearly known. After death the 
spleen is found greatly enlarged and softened, the kidneys broken, dung 
and the blood fluid. 
How to Know It. 
The period of incubation extends over four or five weeks after the poi- 
son has been introduced. The fever will at first be moderate, the tem- 
perature as shown by a clinical thermometer, introduced into the rectum, 
will be 103 to 107 degrees. Then follows dullness, cough, trembling, 
jerking of the muscles, drooping of the head, arching of the back. The 
horns are hot, rumination ceases, and the appetite not good. The eyes 
become glassy and watery, the urine deep red or black from the blood 
contained ; the dung is hard and coated with blood ; the mouth and rec-

or convulsions. 
Gamgee always found present in the examination of nearly 5,000 
animals that the fourth stomach was distinctly inflamed and the spleen
