376 TUMOURS OF THE HEAET. 



3. In referring to cardiac polypi, I may draw attention to a 

 paper by my brother, Mr Arthur Gamgee, published in the 

 second volume of the Edinburgh Veterinary Review, p. 30, 

 in which a specimen is described as follows : 



" CASE I. Tumour occurring in the left Auricle of the 

 Heart of a Cow. The morbid specimen, of which a drawing 

 is appended, was brought to the New Veterinary College 

 from the Edinburgh slaughter-houses. The heart had, by the 

 man who had killed the animal, been at once recognised as 

 presenting an abnormal appearance; no account was, how- 

 ever, forthcoming of the state of the beast during life. The 

 heart weighed 5 Ibs., and with the exception of very great 

 distention of the left auricle, appeared quite healthy. The 

 left auricle had been cut before it was brought to us, and from 

 the opening a fibrinous mass protruded. The left ventricle 

 was first opened by a longitudinal incision along the septum 

 ventriculorum, both on the anterior and posterior surface. 



" Description. On examining the auricle through the auri- 

 culo-ventricular opening, it is found distended by a tumour, 

 which so thoroughly obstructs the opening as to render it a 

 matter of mystery how blood could pass through the pulmon- 

 ary veins into the ventricle. On making an incision from 

 right to left along the upper surface of the auricle from the 

 body to the auricular appendage, the tumour is observed 

 to fill the whole extent of the cavity, to the right side of 

 which it is attached by a broad base. On drawing out the 

 tumour from the auricle by turning it on its base from left 

 to ri^ht, it is exposed in the position shown in Pig. 116. 



" Around the tumour shreds of blood-clot exist, but the 

 mass itself has a pinkish-yellow colour, rather nodulated on 

 the surface, which is smooth, with the exception of a consi- 

 derable patch of gritty roughness and greyish-yellow colour ; 

 at the lower surface, the shape of the tumour exactly repre-
