 tagious diseases, but with doubtful efficacy.

 phate of zinc is used in veterinary practice. In this connection it is

 healing process. It is also useful as an injection in leucorrhoea in mares.

 out of indigestion.

 ing. Sometimes given as a tonic in combination with vegetable bitters.

 worm. In its gaseous condition it is employed for disinfecting stables,
