VALERIAN. S97 



Doses. The doses of oil of turpentine for horses and 

 cows are from one to two ounces, always mixed with its 

 own bulk of oil, especially for horses. For dogs affected 

 with tape-worm, half to one drachm is the 'dose, mixed 

 with the yolk of an egg. 



(6.) Rosin, or Resin. — The residue left from the dis- 

 tillation of turpentine, which is chiefly used by horsemen to 

 cause the horse to urinate more freely. Much mischief is 

 often done to horses by the administration of rosin. In- 

 deed, most diseases of the kidneys and of the loins can be 

 traced to over-dosing with this substance. The oftener 

 rosin is given to the horse, the more he appears in the eyes 

 of the driver to stand in need of his favorite dose. The 

 kidneys become over-worked, the desire to urinate is more 

 frequent, less urine is voided each time, and the poor man 

 does not see the mischief he has alreadv done, but hastens 

 to give the horse more to remedy the urinary defect he has 

 thus been instrumental in producing. It will be well to 

 remember that powerful diuretics, lik^e ])owerful purgatives, 

 tend only to weaken and debilitate. If there be a urinary 

 defect, find out the cause, and, if possible, have it removed, 

 and the effect will cease, '^ sublata cmtsa, tolUtur effectus,^* 

 but do not attempt to do so by force, and against all science 

 and common sense. Other preparations of turpentine have 

 already been noticed. (See Tar.) 



TJrse XJrsi. — The leaves of the whortleberry. They 

 were once in repute in diseases of the horse, but are now 

 fallen, and others have taken their place. They were used 

 chiefly in diseases of the bladder and kidney. 



Valerian. — Valeriana Officinalis. However useful 

 valerian may be in nervous irritation in man, it is not so 

 useful in veterinary patients. Camphor, and the gum
