PHLEBOLITES. 441 



so readily as he had been accustomed to do. When Mr Thacker first 

 saw him, the symptoms were total loss of appetite; the pulse at the 

 jaw accelerated, but faltering ; a kind of pulsation in which the prac- 

 titioner rarely feels himself warranted in abstracting blood; at the 

 heart the pulsation was fuller, in number 65; the respiration was lan- 

 guid and heavy; the extremities were .not particularly cold, and the 

 visible mucous membranes were slightly injected. There was a pecu- 

 liar spasmodic contraction just anterior to the left spinous process of 

 the ilium a jerking action, as if connected with the internal abdomi- 

 nal muscles. There was also a degree of tenderness on the right side, 

 over the region of the liver, an obstinate constipation of the 

 bowels, but no turning of the head to the side, nor any desire to 

 lie down, although he was evidently suffering from abdominal pain. 

 No lameness of the leg was at this time observable, but it was 

 rested. From the general symptoms, I was inclined to think 

 that the illness arose from some derangement of the digestive 

 organs, more particularly of the liver, not, however, amounting to hepa- 

 titis; and notwithstanding the peculiarity of the pulse, to which 1 have 

 referred, the symptoms otherwise warranted me in attempting to with- 

 draw blood. I, therefore, directed Mr Thacker to open the left jugular 

 vein, in order to ascertain what would be the result. Keeping my hand 

 at the side, I watched the pulsation at the heart. The vein was readily 

 opened, and the blood for an instant flowed out of the vessel freely, but 

 as quickly ceased. By keeping up the pressure, similar effects were 

 produced. Finding that the animal did not bleed readily, I left his 

 side, in order to examine the vein, and immediately detected the pre- 

 sence of an enlargement a little above the entrance of the jugular into 

 the thorax. At first I was inclined to think that there had been inflam- 

 mation of the vein, and that other conduits were taking the blood from 

 the head to the heart; in fact, that there was an obstruction to the 

 flow of blood through the vein. But, on examining more minutely, I 

 discovered this tumefaction to be caused by tumours, which at first 

 sight bore a strong resemblance to enlarged absorbents. This horse had 

 been a short time previously in a stud where there were several cases of 

 farcy and glanders, and hence I was naturally led to infer enlarged ab- 

 sorbents; but, on a still more careful examination, they proved to be 

 tumours within the jugular vein. You may now see their situation : they 

 are very evident, and placed about half-way down the neck. "When I 

 first detected them, they were somewhat lower down than they are
