90 SPECIAL VETERINARY THERAPY 



soluble and in solution almost tasteless so that it can 

 be given in the drinking water. For horses, two 

 drams, three times daily in drinking water is a sure 

 preventive of the above disease. 



It is also very useful in cystitis, urethritis and 

 arthritis, besides possessing valuable properties as an 

 intestinal antiseptic. It has been held that it must be 

 given in conjunction with an acid. Clinically this has 

 not been found necessary. 



Passiflora Incarnata. 



The fluid extract of this drug is of real worth in 

 veterinary practice. In all conditions other than sur- 

 gical operations, in which it is desirable to relieve 

 pain, passiflora stands first in the list of drugs. 



Its action is more one of calm sedation than of 

 hypnosis or narcosis and this effect may be kept up 

 indefinitely by proper dosage without any bad after- 

 efifects whatever. 



An ounce dose can be given every hour if necessary 

 until the physiological effect is produced ; then its 

 administration less often will maintain this effect. In 

 conditions in which opium or morphine are contra-in- 

 dicated, passiflora may be used effectually. 



Mercurials : 



Of these the most serviceable in veterinary prac- 

 tice is the proto-iodide. It has real value in general 

 infections and glandular diseases in from two to three 

 grain doses, especially when chronic. 



In the secondary pustular and suppurative condi- 

 tions of canine distemper doses of one-sixteenth grain 

 work wonders.
