order. If, as seems to have been the case in the early nineties^ 

 the movement of sheep from the infected flocks and pastures- 

 tends to cause the disease, this should be legally interdicted. 

 Finally, the complete extermination of the sheep on infected 

 areas could be practiced, and their places supplied by the immune 

 Angora goat.

 JAUNDICE. PIROPIyASMOSIS. 



Distribution : Senegal, Lyons, B. Africa, Paris, Pas de Calais, Cape- 

 Colony. Microbiology : piroplasma, differentiation from that of Texas^ 

 fever, pathogenesis, tick-borne. Symptoms : incubation 3 to 5 days^ 

 dulness, prostration, apathy, drowsiness, anorexia, thirst, hyperthermia, 

 icterus, haemoglobinuria, offensive odor, emaciation, protozoon in globules,, 

 loss of globules. Death in collapse. Lesions : body shrunken, emaciated, 

 foetid ; dark tissues, mahogany yellow, petechias, enlarged congested liver

In certain malarial districts dogs suffer severely and even, 

 fatally from a febrile affection in which violent shivering is fol- 

 lowed by great hyperthermia and yellowish or brownish red dis- 

 coloration of the visible mucosae. It was frequently attributed 

 to malaria, and even sought to be identified with intermittent 

 fever in man. Marchoux in 1899 studied this disease on the- 

 malarious seaboard of Senegal, and recognized the existence of 

 hsemoglobinuria and the presence in the red globules of a hsema- 

 tozoou. Leblanc, about the same date, found a protozoon in the 

 blood of dogs at I^yons, suffering from ' ' red water, ' ' and Koch 

 later found a double piroplasma in the red globules of suffering 

 dogs in East Africa, both considering the disease analogous to- 

 Texas fever in cattle. Nocard and Almy in 1901, at Charenton,. 

 Paris, met with a similar affection in a dog which had just re- 

 turned from a fox hunt, and was covered with ticks. Its urine 

 was brownish red, like coffee grounds, and highly charged with, 

 albumen and haemoglobin. Many of the red globules were 

 affected and contained minute, spherical refrangent bodies which, 

 when stained with carbolized thionine, appeared like those of
