372 ULCERATION OF PEYER'S PATCHES 



XIX.— ON A DISEASED CONDITION OF THE 

 INTESTINAL GLANDS." 



Without enteriug upon the question, as to whetlier the 

 subject of the present paper constitutes a distinct species of 

 disease, or be merely a form of the ordinary continued fever — 

 a question which I am quite satisfied will never be answered 

 so long as each pathologist confines the inquiry to the fever 

 of his own district, without connecting with it the consider- 

 ation of those forms of fever which occur in every separate 

 district of a country or continent — I shall proceed at once to 

 describe a lesion which I observed some time ago in a disease 

 which I was led to consider as typhus or continued fever. 



On opening the abdomen of individuals who had died of 

 this fever, we could always recognise the diseased condition 

 of the internal surface of the gut by the elongated bluish 

 purple spots on its peritoneal surface, corresponding to the 

 glands of Peyer on the internal surface ; and this we could 

 do, even in those cases in which, from other circumstances, 

 the vascularity of the parts had disappeared after death. 



On laying the gut open, the patches of Peyer's glands ex- 

 hibited, according to the standing of the case, the various 

 appearances which I shall now describe. 



But before proceeding to detail the phases through which 

 the patches pass, from the first appearance of the disease till 

 the establishment of the typhous ulcer, or of perforation, I
