lour, and in many cases losing the power of coagulating when 
drawn from the arm, and in all cases being more loose in texture; 
and when death ensues during the course of the disease, the blood 
contained in the heart and large vessels is dark and fluid. 
14th. That inflammation of the membranes of the brain, of the 
bronchia, and of the mucous membrane of the stomach and intes¬ 
tines, and various febrile affections arising from cold, fatigue, im¬ 
proper ingesta, &c. &c., more particularly disease of the aggregated 
glands of the ilium, and the mucous follicles, usually termed dothen- 
enterite, have been confounded by medical practitioners with typhus 
fever, and are characterized by dissimilar symptoms, and require a 
very different mode of treatment. 
15th. That the congested state of the vessels of the brain, the 
serous fluid on its surface, and the dark fluid state of the blood are 
the most constant morbid appearances to be met with in post mor¬ 
tem inspections of those who have died of contagious typhus; and in 
many cases the only morbid appearances which are to be found, and 
the next in frequency, is the thickening or darker appearance of the 
lining of the bronchial membrane; and the third in order is the dis¬ 
eased state of the mucous membrane of the intestines, more parti¬ 
cularly that of the aggregated glands of the ilium. The relative 
proportion of these states to each other varies considerably, according 
to the state of the weather as to heat, dryness, &c. 
16th. That dothenenterite, or enlargement of the mucous follicles of 
the smaller intestines, and enlargement and ulceration of the aggre¬ 
gated glands of the lower third of the ilium, occurs in combination 
with contagious typhus, and is to be met with in about one in six of 
those who die from typhus, but that it also exists as a disease per se, 
where it is characterized by the following symptoms: A quick, irri¬ 
tated pulse; tongue dry and florid at the tip or throughout, often As¬ 
sured in centre ; thirst urgent; eyes clear ; no complaint of frontal 
headach ; face alternately flushed and pale, more particularly flush¬ 
ing of one or both cheeks ; less decided anorezia; pain of epigas¬ 
trium, or in the right and left iliac regions on pressure ; occasional 
vomiting of a greenish fluid; stools in general natural; abdomen 
slightly tumid and puffy, but the patient makes little complaint. 
The disease may exist in every degree of mildness or severity, having 
no regular period of termination; it may run on for two, three, or 
even four weeks, and terminate in gradual restoration to health with¬ 
out any sensible crisis; or the patient may sink under it from ex¬ 
haustion, or by haemorrhage from the bowels; or it may end by 
some of the ulcers of the aggregated glands of the lower third of 
the ilium penetrating the coats of the intestines, and part of the 
contents being effused, exciting peritonitis, under which the patient 
sinks in the course of two, or at most three days. 
The less compressible state of the pulse, the clearness of the eyes, 
the flushing of the cheeks, the more florid, parched, and fissured 
state of the tongue, the comparative absence of the frontal headach, 
and the complete absence of the typhus eruption, sufficiently distin¬ 
guish this disease from contagious typhus. To a practised eye, the
