while feeding of the lymph is, according to Hicard, ineffective. 

 Rickert has inoculated about 700 sheep in the last week of 

 pregnane}-. Repeated inoculations of the lambs born of 

 them remained negative while of 36 lambs from others not 

 inoculated pox occurred 9 days after the inoculation. After 

 three years inoculations in the case of the former had positive 

 results but in the latter no longer. In the same way Adacker 

 has inoculated 60, Peuch 3, lambs born of sick mothers without 

 any result (the latter also 3 kids). 



424. Goat Pox. \^ariola caprina. The goat pox was 

 formerly observed in Sweden. It has been found in Italy, 

 Spain, France. Germany and in Algeria. It has been reported 

 that in Algeria it is occasionally very severe. 



Etiology. The contagion of goat pox can be transmitted to 

 goats through the pock content and when the pustules are in 

 the mouth through the saliva of the sick animals. After 

 cutaneous inoculation a local eruption develops at the place of 

 inoculation associated with very mild general symptoms. Man 

 is not entirely unsusceptible, as there appears, especially on the 

 hands and arms of people who care for the sick goats, an 

 exanthema with little vesicles (Hansen, Marcone). 



Natural infection takes place by direct touch and the 

 disease in this way spreads quickly into the herd of goats so 

 that as a rule almost all the animals are infected (sheep kept 

 wich the goats are never affected). On the other hand the 

 disease shows no inclination to spread to wider territories but 

 usually stays confined to one herd. 



The manifestation of the disease is very similar to the 

 sheep pox. In connection with a moderate fever there develops 

 large pustules partly confluent and with a depression, on the 

 most diverse parts of the body, especially on the udder, the 

 inner surface of the extremities, the face and around the lips 

 and eyes. These leave radiating scars. In many cases 

 abscesses form in the tissues of the udder, and at the same 

 time the milk becomes bloody. In certain animals, especially 

 nursing kids, there also appear in the mouth, as well as in the
