A CASE OF CUTANEOUS PAPILLOMA IN A COW. 
By Peof. Yigezzi. 
The subject of this observation was a two-year-old heifer; 
the tumors being generalized in almost all the regions of the 
body, and varying in size, from that of a small nut to 
that of a child’s head, The largest warts were removed 
with the bistoury, the excisions being performed on two dif¬ 
ferent occasions. The total mass removed weighed about 
eleven pounds. The author suggests some interesting con¬ 
siderations upon the pathogeny of warts and their curious 
mode of elimination. 
In 1871 Richter published a paper containing sundry obser¬ 
vations of warts in man, in which he speaks of seeing between 
the central substance and the periphery microccocci which, 
no doubt, were the agents of contagion. This case of Richter 
passed unnoticed, and ten years later, in 1881, Maiocchi dis¬ 
covered in a cow the presence of a special organism to which 
he gave the name of Bacterium porri. 
Maiocchi and Piana succeeded in inoculating upon them¬ 
selves the discharge from the wart of a cow, and Vachette 
showed the contagiosity of bovine to bovine. This transmis¬ 
sion is difficult to reproduce experimentally, and the author 
obtained no results upon a donkey, a dog, or a goat with warts 
Irom the cow. 
As to the mode of elimination of the warts, Ercolani has 
studied them and his conclusions are proved by the researches 
of Maiocchi.t It is the result of an obliteration of the blood¬ 
vessels whose internal epithelial coating becomes hyperplastic ; 
sometimes also there is endarteritis and periarteritis, the two 
processes being two forms of obliterating angioitis.— Resoconto
