ject we would, in conclusion, remark, that it appears to us, that the 

 deposit of typhus matter, so called, occurs not only in the intestinal 

 follicles and mesenteric glands, but also in and beneath the mucous 

 membranes, in the lungs, spleen, and probably in the kidneys; that 

 in some cases this form of epigenesis shows itself mostly, if not exclu- 

 sively, in the intestines, in others in a different part, and in others 

 again in various tissues ; that in some instances it is not discovera- 

 ble in any organ ; that in the typhus of some seasons and countries 

 it is generally present in the intestines, and in others, absent in 

 many or a large majority of cases.
