CONTAGIOUS DISEASES OF DOMESTICATED ANIMALS. 15 



a fifth, 6 had died. There had, consequently, been at least 55 deaths f 

 in addition, a certain number had partially recovered, and some diseased 

 animals had been sold. 



According to the l)est information we could obtain the total number 

 of cases of pleuropneumonia which had occurred in this county was 

 not less than 100. These herds were quarantined and the State authori- 

 ties are doing everything possible with their limited ai)propriatiou to 

 stamp out the disease ; but where so many animals have been e^xposed, 

 and where the contagion has been sown broadcast over the pastures of 

 half a dozen farms, experience shows that it is next to impossible to 

 remove all danger except by killing all animals exposed and quaran- 

 tining the farms for a long time. 



MARYLAND. 



Owing to the variety of reports in regard to the existence of pleuro- 

 X)neumonia in Maryland, Dr. Kose was directed to proceed to Balti- 

 more during the last week of October, 1883, and examine a sufficient

 tribution of the disease in that section. The cases of sickness men- 

 tioned are only those in which the symptoms indicated pleuro pneu- 

 monia. The following is a list of stables in the order in which they
