cattle, — the most important production, and that which 

 ought most to be encouraged, that of beef. The German 

 countries give us an example of energetic measures. Why 

 should we hesitate to follow them ? 



" When the invasion is well ascertained, public function- 

 aries should advise the destruction of all the cattle in the 

 barn where the disease has established itself. If the 

 owner refuses to take this advice, good as well for him 

 as for the public at large, the public officer ought to do 

 all in his power to hem in the disease, and to prevent the 

 animals from an infected barn from being brought in con- 

 tact with others in the pastures, or to be driven to the 

 markets and the fairs. In fine, it will be necessary to 

 establish around the locality of the infection a kind of 

 cordon sanitaire, to notify the prefect and the minister of 

 agriculture, and to raise a loud cry of alarm, because 

 no malady has ever done so much evil as pleuro-pneu- 

 monia." 



The outbreak of this disease can be traced invariably to 

 the introduction of cattle from abroad, and its spread and 

 extension can only be prevented by the immediate and 

 complete isolation of the infected animals from others, or 

 the destruction of all animals in which premonitory symp- 

 toms appear, and those which have been exposed to the 

 infection. 



As already intimated, the first stage of the disease is 

 the only period when it can be cured ; and after it has 

 become fixed upon the lungs, dosing is of little use, and 

 the animal ought to be destroyed. 



In the first stage, Collot recommends u bleeding slightly 

 in the neck, and rubbing the whole body for half an hour 

 with whisks of straw, and then to cover the animal and 

 leave her alone. Three or four hours after bleeding he 

 would give an emetic in warm water, followed by eight 

 similar doses two hours apart ; during the intervals of 

 the two hours, moderate quantities of the following 

 beverage : — 



"Boil two or three quarts of barley for ten minutes in 

 about two gallons of water ; then pour off this water, 

 which contains the acrid principles of the grain, and re-
