ENGLISH REVIEW. 
Equine Tuberculosis. —Though typical tuberculosis is 
not very common in horses, it seems that in some exceptions 
the disease can be observed almost frequently. In the Veteri- 
nai'y Record^ four cases of equine tuberculosis are recorded by 
W.^ Cauldwell, F. R. C. V. S., three of which occurred in com¬ 
paratively young horses: a grey colt, i8 months old, a bay colt, 
2 years, and a bay filly, 3 years. The fourth case was in a 
brown gelding, 9 years old. In the first animal the disease was 
extensively generalized, in the second the bones and the spleen 
presented the principal lesions, the third presented tuberculous 
deposits in the spleen and udder, the fourth had principally 
tuberculosis of the mesenteric glands. The diagnosis of the 
o o 
lesions was confirmed by the examination of Prof. McFadyean. 
Case of Intussusception \By F. Porch^ F. R. C. V. S.' 
—It is not always the amount of displaced intestines tha: 
gives rise to severity in the symptoms, and whatever this 
amount may be the acuteness, severity and constant pain are 
sufficient suggestions of the presence of intussusception. And 
it is at the post-mortem that the importance of the lesion is dis¬ 
covered and the chances that possible relief might have been 
obtained, are found. In the case recorded by the author he de¬ 
scribes a post-mortem which is unusual in the amount of intes¬ 
tines involved. He says: ' “About three and a half feet of the 
ilium was distended and hard from some substance within it. 
This was cut out, then from the distention was drawn out a 
mass of involuted bowel, which measured just ten feet.” We 
think that few veterinarians have met such extent of intestine 
involved .—{Veterinary Record.) 
Lame in Harness Only. —Mr. T. J. Wooff, M. R. C. V. S., 
records the peculiar case of a horse which he had purchased 
lately for a client and passed as sound and which the following 
day showed lameness while at work in harness. Examined un¬ 
der different conditions he was found sound or lame. Sound in his 
standing position, sound in walking and trotting when led, but 
becoming lame as soon as put to work in action. The author 
concludes that the collar had some part in the production of the 
lameness, but is unable to locate the deeper cause of the trouble. 
This funny case reminds us of one in which the horse would 
literally play lame. He belonged to a physician in New York,
