DISEASES OF THE SPINAL CORD. 309 



SPINAL H^MOREHAGE. 



In rare instances, ha3niorrhages in connection with the 

 spinal cord have been met with from a diseased condition 

 of the vessels. Generally, however, haemorrhage is a 

 snrgical lesion, the result of direct violence. 



The cord itself may be the seat of the haemorrhage, or 

 this may occur in the sac between the ensheathing meninges, 

 or finally it may occur outside of the membrane. 



If the extravasation into the substance of the cord be 

 large, paraplegia may suddenly come on in consequence, 

 but when it is of less extent, exaltation of functional 

 activity may or may not be followed by impairment or loss 

 of motor power. 



TUMOURS AND ADVENTITIOUS GROWTHS IN 

 CONNECTION WITH THE CORD. 



Exostoses, melanotic growths and cancerous growths, are 

 sometimes met with in connection with the cord. 



AYe have already alluded to a case of melanotic deposits 

 in the cord. 



An account of a very interesting case of cancer of the spine 

 is thus recorded by Mr. Hunting : 



On the 10th September, 1855, 1 was requested to see a chestnut mare, 

 the property of Mr. G. S. R., of S. H. She had been unwell for ten 

 or twelve days with cough and sore throat ; her neck was likewise very 

 stiff, but her appetite had remained good up to yesterday, when she 

 became tympanitic, and suffered intense pain. When I saw my 

 patient, I found that the pulse numbered 68, and was weak. The sub- 

 maxillary artery appeared full and soft, and the action of the heart 

 feeble. The breathing 59 in the minute, and rather laboured. The 

 conjunctival membranes were very much injected, and of a yellowish 

 colour. The mouth was hot and dry. The nostrils were greatly dilated. 

 The ears were cold, legs warm. The faeces were of a healthy 

 character. The respiratory murmur throughout the whole length of the 

 trachea was much louder than in health, and the left lung gave evidence 

 of partial congestion. The cough was thick and heavy, and of a peculiar 

 sound, but not frequent. The larynx and trachea were very painful 

 on pressure.
