provemeiits seen in cool seasons or stables, under good hygiene, 

 are not recoveries but temporary amelioration only. 



Symptoms in other animals. Corresponding conditions produce 

 similar symptoms in cattle, sheep, swine and dogs, but the disease 

 receives less attention in these animals because they are not called 

 on for steady work. The animals are lazy, dull, insensible to 

 excitement, stupid, show a lack of nuiscular power and control, 

 stagger or move disorderly and show tympanies or other indica- 

 tions of indigestion. 



T7'eatment. Majendie and others had a few apparent recoveries 

 after violent counter-irritation over the spinal cord (cervical and 

 dorsal). Coculet and Lafosse claimed recoveries from the pro- 

 longed use of nux vomica in large doses (up to 5 drachms j. 

 Hayne attempted evacuation of the fluid by puncture through the 

 perforated plate of the ethmoid bone, but had evil results from 

 the ensuing haeinorrhage and encephalitis. Aseptic puncture 

 through the plate of the frontal bone would be much more prom- 

 ising. Klemm suggested hydrochlorate of pilocarpin (15 grains), 

 and this would promise better than an)' other measure to induce 

 absorption of the liquid. The fatal drawback to this as to other 

 measures is that it is not applied until the slow, steady pressure 

 has caused such extensive cerebral atrophy that, even if the liquid 

 could be removed and its reproduction prevented, the lost func- 

 tions can never be restored. If the disease could be diagnosed 

 and treated before this change of structure had taken place, the 

 hope of recovery would be much better founded. Even in ca.ses 

 which make a temporary recovery during cold weather one would 

 be warranted in using active derivatives toward the bowels and 

 kidneys, also pilocarpin, counter-irritation to the spine and even 

 tapping of the ventricles. 



Legal Aspect of Chronic Hydrocephalus. 



To claim relief in case a horse affected in this way is .sold as 

 sound, the seller must be notified at an early date. In the differ- 

 ent countries of Europe a limit is set after which such notification 

 will have no legal value. The seller mu.st be notified, in France 

 in 9 days, in Saxony in 15 days, in Bavaria, Wurtenberg and 

 Baden in 21 days, in Hesse and Prus.sia in 28 days, and in Au.stria 

 in 30 days.
