The Cattle-Plague. 245 



The Condition of the Skin, in tlie proportion of one-tliirtl, 

 nearly, of the cases treated by Dr. SmAET, was such that an 

 eruption appeared generally diflfused, but most abundantly on 

 the flanks. The eruption, as seen on the udder, had a vesicular 

 character ; and the date of its appearance was probably between 

 the 5th and 7th day. Dr. Bristow writes of the eruption ac- 

 companying cattle-plague : — " I have never yet seen a vesicle. 

 I have never yet seen a pustule. I have never yet seen that de- 

 struction of the surface of the skin which in small-pox leads to 

 pitting." Mr. A. B. Squire, M.B., says, in the letter-press that 

 accompanies his exquisitely-executed coloured photographs of 

 skin-diseases: — "It has been a matter of debate whether the 

 so-called pustules of the disease are really deserving of the name. 

 This question, I think, may be decided by the scabs, since scabs 

 presenting the characters here represented (the size and thickness 

 of a split pea) can, if we may argue from human pathology, 

 originate only in jnistulcs of corresponding size." Dr. ChARLES 

 3IUECH1S0X, in his letter to the ' Lancet,' in September, quite 

 confirms Mr. Squire's view by several striking cases. 



On that material point of ulceration, Dr. SmarT affirms : — 

 "The whole mucous lining of the bowels is unduly soft, and its 

 epithelium imperfect. There are no true ulcerations, and in this 

 respect its condition differs broadly from the ulcerated typhoid 

 in man. . . . The mesenteric glands show no lesion of structure." 

 This view I find to be supported by Mr. PoPE, M.R.C.S., 

 of York, whose experience has been scarcely less extensive. Dr. 

 MURCHISOX, who is of an opposite opinion, is sustained by Pro- 

 fessor Roll (' Lehrbuch,' pp. 349-50), Dr. Gant, Professors 

 SiMONDS and GaMGEE. Dr. \Vm. Budd argues also energeti- 

 cally in the same direction. Looking at the tendency of Dr. 

 Brauell's microscopic researches, it would almost appear that 

 what by the naked eye have been taken for pus-globules, are in 

 reality that exuberant growth of cells which is typical of this 

 disease. If so, the typhoid theory founded on the presence of 

 ulceration is somewhat shaken. 



Professor Simonds, communicating the results of his prac- 

 tical acquaintance with the rinderpest in the Steppes to the 

 Royal Agricultural Society of England, in 1857, says: — "The 

 rumen and reticulum (first and second stomachs) are healthy in 

 most cases. In some few instances the epithelium readily peels 

 from off their inner surfaces, when the vessels beneath are found 

 to be turgid with blood. The rumen invariably contains a fair 

 f[uantlty of ingesta in the state usually met with in healthy 

 animals. The omasum (third) is without structural change, or, 

 at most, resembles the first and second. Its contents are frequently 

 ■so dry and hard that they can be rubbed to powder between the
