THE SIMULTANEOUS METHOD. 



In the opinion of the writer the injection of anthrax antitoxin together 

 with a small quantity of virulent anthrax bacteria, at least has the ad- 

 vantage of being given at one time. Such a plan should receive more 

 attention where infected ground is available. 



PREVENTION. 



Having removed all well animals from the barns and yards holding 

 the sick ones, the temperature taken night and morning will indicate 

 any new cases. By careful isolation and safe disposition of the dead 

 animals, the spread of the disease may be checked. Animals do not, as 

 a rule, spread the virus when the first rise of temperature can be detected. 

 The infected stables and yards should be thoroughly disinfected. 



The disposition of dead animals in an outbreak is of much impor- 

 tance. Failing to burn a carcass where it falls, it should be buried 

 deeply and covered with quick lime before the dirt is replaced. Then 

 having fenced the plot, it should be burned over frequently to destroy 

 any spores that might be brought to the surface. 



CEREBRO-SPINAL MENINGITIS. 



Some cattle belonging to a party at Odebolt were pastured and 

 fed at Pilot Mound, where the disease of cerebro-spinal meningitis 

 appeared among them. Other cases occurred in Jefferson county, 

 at Braddyville and Terril, Iowa, and several other points. In most 

 of these cases the disease was attributed to the use of mouldy food. 

 A notable case of ensilage poisoning was discovered in Story county, 

 where a farmer lost eight head of horses within a few days. The 

 State Veterinarian investigated this case, and located the source 

 of the poisoning in mouldy ensilage caused by a leak in the silo. 

 It is advisable to exercise care in the preparation of all feeds in 

 ^rder to avoid the development of fungi poisons. 



Report on a few outbreaks of cerebro-spinal meningitis by John 

 '/homsen, Assistant State Veterinarian : 



This rather fatal, indefinite affection of domestic animals, epizootic 

 in nature, at times common in certain districts, attacks mainly the central 

 nervous system, the brain and the spinal cord, and especially the menin- 

 ges or covering of those structures. Of late it has been thought by 

 some writers to bear some relation to the disease known as Pallagra in 

 man. It attacks horses, cattle, sheep, goats and dogs, apparently by pref- 

 erence the young or those whose resisting power to the attack of the 

 disease had not had time to develop. One attack does not give immun- 

 ity as animals have been known to pass through three attacks, being 

 affected for a week or more each time.
