For the embryos in the distended synovial sheaths and joints, 

 the antiseptic extraction, by aspirator if necessary, of the infested 

 synovia, and the injection of a uon-irritating vermicide. For 

 this purpose a solution of pyoktanin (i:iooo) with or without a 

 small admixture of cocaine. Or a weak compound solution of 

 iodine and iodide of potassium may be used ; or, again, a weak so- 

 lution of quassia in well boiled or distilled water. Such agents 

 being absorbed into the lymph vessels, will tend to the destruc- 

 tion of the embryos that may have entered these channels. 



PSOROSPERMOSIS FROM BALBIANIA GIGANTEA IN RUMINANTS 



AND PIGS. 



This sarcospore has been found extensively distributed in the 

 voluntary muscles of the head and trunk, and in the heart, but 

 especially in the oesophagean muscles of the ox, buffalo, goat, 

 sheep and pig. It may vary in size from a grain of wheat to a 

 hazel-nut, and is recognized as a whitish spot 3 to 5 lines in 

 length by I ^ lines in thickness. It has a delicate outer mem- 

 brane enclosing a mass of cells. In the centre of the larger ones 

 is a capsule the size of a pin's head filled with arcuate or crescent- 

 shaped non-nucleated bodies. The psorospermise may be of any 

 number from two to two hundred, ten or fifteen being quite com- 

 mon. 



They are not known to do any harm, yet Niederhausern and 

 others believed them to be the cause of sudden deaths, because 

 they had induced dropsical effusion in the vicinity of the larynx. 

 The symptoms were those of asphyxia, and in other cases of 

 epileptiform attacks.
