In a word, then, typhous diseases have their 

 types ; but the living being is subjected to so 

 many different influences, hereditary, idiosyn- 

 cratic, climataic, hygienic, &c., that by the 

 side of one subject going through the course 

 of morbid phenomena with fatal regularity, 

 another may be seen in which such or 

 such functional derangement is readily dis- 

 tinguished. Thus in some animals, predis- 

 posed thereto by prior disorders, the morbid 

 action originally propelled towards the chan- 

 nels of respiration will continue to be most 

 salient ; and after dissection the lungs will be 

 congested and emphysematous, and the intes- 

 tines relatively but scarcely altered. The 

 animal, indeed, though bordering on typhus, 

 will sink under the effect of functional de- 

 rangement in the breathing passages. In 

 others, by the influence of some particular 

 predisposing cause, disorders of the nervous 

 centres will be signalized; a cerebral and 

 spinal pains will be intolerable, delirium will 

 quickly ensue, and the asphyxiated patient, if 

 a man, will succumb in the course of a few
