Salicylic acid is of value in skin diseases with induration, and for 

 removing horny growths as warts and corns. For the latter it is mixed 

 with collodion (3ii in §i) and applied twice daily for a week or so when 

 the growth comes away without any irritation. 



Salol is used as an antiseptic dusting powder of uncertain value. 



Uses Internal. — The salicylic acid group are specifics in rheumatic 

 fever. They lower temperature, lessen pain, and by shortening the attack 

 lessen the danger of cardiac complications. Sodium salicylate should be 

 given every three hours in doses of 3ii to horses, and gr.x-xx to dogs. 

 But this form of rheumatism is rare in veterinary practice, and salicylic 

 acid is unfortunately not nearly so valuable in the treatment of other 

 varieties. Salicylates are probably worthless in chronic rheumatic arth- 

 ritis where the local application of heat, stimulating liniments and blisters 

 are serviceable; but they may be used with benefit in acute muscular 

 rheumatism, sciatica, and rheumatic complications of influenza in horses. 

 Salicylic acid, salicin, and salicylates are not comparable with the coal 

 tar products as general antipyretics, and are useless in hyperpyrexia. 

 Sodium salicylate is sometimes prescribed in gastric fermentation of 

 horses when the salicylic acid, set free by the hydrochloric acid of the 

 gastric juice, acts as an antiseptic. Also in colds and acute pharyngitis, 

 and in chorea and pleurisy, all of which may be of true rheumatic (strep- 

 tococcic) origin. Salol is a good intestinal antiseptic in diarrhea and 

 intestinal indigestion, particularly when, combined with bismuth subnitrate 

 in powder or aqueous mixture for dogs. Salol is undissolved in the 

 stomach, is less irritating than either salicylic acid or sodium salicylate, 

 and is prescribed to lessen pain and fever. It may be advantageously 

 given to dogs, for painful rheumatism, as follows : 



Phenylis salicylatis. 



Acetphenetidini aa 3iss. 



Codeinae sulphatis gr.vii. 



M. et divide in capsulas No. xxx. 

 S. Two capsules t. i. d. 



It is probably inferior to sodium salicylate, but can be conveniently 

 administered in powder as just noted. Salol is also a local anesthetic
