cause. Twenty-five days after the attack lie died. The right 

 vcDtricle presented an old rupture, which showed for some 

 breadth the commencement of cicatrisation. 



POLYPUS OF THE HEART. 



A case of this is related by Mr. Kay, V.S., Pontefract, 

 Yorkshire, in the sixteenth volume of The Veterinarian, 

 p. 555, occurring in ^'quey^^ (or steer) calf, 13 months old, 

 which gave no pathognomomic symptoms of its disease until 

 the fourth day, when Mr. Kay, " after a careful diagnosis of 

 the case, arrived at the conclusion, from the irregularity of 

 the circulatory system, that something abnormal must exist

 calves about the same age^ and both out of the same cow, 

 exhibiting the same symptoms previous to death." 



TUMOUR OP THE HEART. 



Mr. Shenton, V.S., Bakewell, Derbyshire, has in the 

 twenty-fifth volume of The Veterinarian, related cases, 

 both in the cow and horse, of the above. In an old cow he was 

 called to, whose case from the first was "hopeless," and who 

 shortly died, he found, though the lungs were "in a per- 

 fectly normal condition," when he came to open the heart, 

 "growing from the septum ventriculorum," a large tumour, 

 the size of a common breakfast-cup. Attached also to the 

 tricuspid valves and chordae tendinese were numerous other
