THE DISEASES OF CATTLE. 255 



Supposing or rather suspecting the disease to be constitu-

Iodide of potassium, 1 ounce.

Tincture of goldenseal, 2 ounces. 



Water. 2 quarts. Mix 



The dose is one sixteenth part of the above quantity ; to be 

 administered daily. 



PRELIIVONARY TO HOKN-AIL. 



Many very valuable animals die prematurely ^ under treatment, 

 in consequence of mistaking symptoms for the disease. 



IJefbre I discuss hom-aiU I propose to offer a few brief remarks

 WHICH EXIST IN THE ANIMAL ECONOMY. 



Sympathy. — The animal structures are so sympathetically 

 related to each other, and so dependent are various organs and 

 finictions on an equilibrium of vital action, based on the law of 

 sympathy, that the animal economy, as a whole, may be said to 

 compose a vast machine, the integrity of which depends on the 

 free and full play of all parts composing its intricate mech-

The media by which sympathy is aroused and maintained, 

 are the nerves. These originate from the brain and medulla

 that of the region in which they are found ; hence we have 

 seven pairs of nerves issuing from the cervical region (neck), 

 eighteen from the dorsal (back), five from the lumbar region, 

 and five sacral, within the pelvis, four coccygeal ; making in all 

 forty-nine pairs cerebro-spinal nerves. They are distributed from
