INTUSSUSCEPTION. 275 



It occurs in all animals, and though almost invariably fatal, 

 there have been instances of recovery. I have seen the ac- 

 cident only in the horse and dog, but notwithstanding the 

 fixed position of the intestine in the ox, intussusception has 

 been seen in the large intestine even of this animal. 



Symptoms. Severe colic, with total obstruction, rejection 

 of enemata, and the persistence of pain. I remember at- 

 tending a case in London in 1851, in which the horse stood 

 obstinately for two days sitting on his haunches at all 

 times a very ominous sign and looking round most anxiously 

 to his flanks. This case proved to be one of intussusception 

 of the caecum. 



Mr Percivall says: " The only distinguishing symptoms I 

 have been able to detect in such cases as volvulus or intus- 

 susception, are : instead of the animal lying down and rising 

 continually, and pawing and stamping, and evincing all that 

 restlessness he does in colic and enteritis, he generally manifests 

 the greatest propensity to lie down; lying down and remain- 

 ing down, only trying from time to time various new postures 

 for relief, such as lying now upon his side, then rolling upon 

 his back, and afterwards by stretching out his fore-legs, plac- 

 ing himself upon his belly, and from thence raising himself 

 upon his hind-quarters like a dog, groaning all the while 

 and casting many a dolorous look backwards at his belly. 

 He will seldom rise of his own accord; but you may rouse 

 him up ; no sooner, however, is he up than he begins turning 

 himself round, with his nose poking ^down, looking about for 

 a fresh place to lie down upon. His pulse is not quick, but 

 soft, and nowise thready or contracted." 



Mr John Field, who is very practical in all his remarks, 

 states the symptoms to be 



"Pain; restlessness, in some cases approaching to madness, 

 unrestrainable ; wandering about; rolling on the back;
