ture-firing is most effectual in hastening resolution in a re- 

 cent one. For those serious cases of general tarsitis,' in 

 which almost every structure of the whole articulation is in- 

 volved, line-firing is also the most effectual. For bog-spavin, 

 large enough or painful enough to require treatment, line- 

 firing gives the most satisfactory results. In line-firing the 

 hock, the lines are carried around the entire articulation, and

from the level of the os calcis superiorly to that of the meta- 

 tarsus inferiorly. (Fig. 69.) Firing a limited area directly 

 over the bone spavin or bog-spavin, or only firing one side of 

 the joint, is absolutely ineffectual except in^the case of deep 

 puncture-firing, and even in this instance the stabbing of a 

 liberal area is desirable in order to provoke as much local 

 disturbance of the skin and underlying'structures as possible.
