times less properly called distemper and dog plague. At first experiments were 

 made with the ticks in the younger stages, and no infection took place. Later experi- 

 ments with adult ticks showed that the blood parasites which cause the disease are 

 readily transmitted by adult ticks. The common dog tick of the Cape region, and 

 the one with which experiments were made, is HsemaphysaUs leachi. It apj^ears that 

 infection can pass from the mother ticks into the eggs, and that the blood parasite 

 requires some time for reaching a stage in which infection of the dog can take place. 

 It appears, therefore, that the ticks are not merely transmitting agents but true sec- 

 ondary hosts for the blood parasites. 



A previously undescribed chicken epizootic, A. Krausz (Ceidbl. Baki. u. Far., 

 1. Ab(., 29 {1901), Xo. 25, pp. 980-982). — An epizootic outbreak occurred in a large 

 hennery where fowls have recently been imported from Italy. The di.sease attacked 

 chiefly the young fowls, and affected birds quickly lost their appetite, remaining 

 standing in one place, and appeared sleepy. Underneath the lids an (edematous 

 swelling appeared, and in many cases the eyelids were stuck together. Death 

 occurred in a majority of cases 10 to 15 minutes after the chief symptoms appeared. 

 Post-mortem examinations showed that the veins were filled with blood and all vital 

 organs were congested. The liver was somewhat enlarged. Bacteriological inves- 

 tigations showed the presence of an organism which was identified as S(ap]i>/lucoccus 

 pyogenes albus. Inoculation and feeding experiments with this organism gave nega- 

 tive results, but no young chickens were to Ije had for such experiments. Isolation 

 of diseased birds and disinfection of their (piarters wore completely effective in check- 

 ing tlie progress of the disease.
