quite evident that this cannot be considered as a permanent un- 

 soundness, and one for which a contract of sale can be justly 

 annulled. But on the other hand, while the eccentric source of 

 irritation which is easily curable may have been the active agent 

 in developing the seizures, it may be none the less true that the 

 central infirmity which determines the abnormal susceptibility, to 

 excessive generation and epileptic explosion of nervous force, 

 may also be present and the animal cannot be considered as 

 sound until a sufficient length of time has elapsed after the re- 

 moval of the peripheral irritation and no new seizure has taken 

 place. 



Treatment of Symptomatic Epilepsy. In cases due to an ec- 

 centric irritant the first step must be the removal of such irritant. 

 In case of intestinal worms the various vermicides and tseniacides 

 must be resorted to. (See Intestinal Parasites). For the 

 linguatula tsenioides the injection of benzine or tobacco water 

 into the nose, or into the sinuses, with or without trephining may 

 be resorted to. In diseased teeth extraction or filling may be 

 demanded. In dentition-irritation, lancing of the gums. In all 

 other cases in which a peripheral nervous irritation can be traced 

 every available means should be taken to remove it. 



Treatment of Central Epilepsy. Bearing in mind that peri- 

 pheral irritation is a frequent exciting cause of a seizure, too 

 much care cannot be. given to the conservation of the general 

 health and especially to make the diet wholesome in quantity, 

 quality and time of feeding and watering, and to guard against 

 constipation and indigestion. In dogs a too stimulating meat 

 diet is to be avoided. 



The medicinal agents employed have been mainly such as are 

 sedative, or tonic to the nervous system. Valerian was long ex- 

 tolled as a valuable remedy (Gohier, Delafond, Delwart), and 

 this has been improved upon more lately by substituting valerian- 

 ate of zinc. Belladonna and its alkaloid atropia have been 

 strongly advocated (Tisserant, Bernard, Williams, Friedberger) 

 and it has the recommendation that it causes vaso-motor contrac- 

 tion and tends to lessen cerebral congestion. Hyoscine or du- 

 boisine may be used as a substitute. Cyanide of iron has been 

 lauded by Jourdier and Tabourin, as far superior to valerian. Of 

 late years the nerve tonics, zinc compounds (oxide, sulphate,
