DISEASES OF ADULT LIFE. 36] 
give a treatment suitable to the symptoms, and wait. Hooper, 
a great authority on pathology, that 1s. describing diseases, 
Says: ‘* Great muscular prostration and early head symptoms, 
with depression of the senses and mental faculties, mark the 
Onset of typhus, whilst symptoms more or less obscure of 
gastro-intestinal disturbance indicate the presence of enteric- 
typhoid fever; but sickness and diarrhcea may be absent. 
Even head symptoms may be present from the first of the 
disease. Although the diagnosis may be difficult at first, yet 
it is no longer so when the disease has advanced. Tender- 
ness about the navel and lower nght side. with a thickly 
coated aphthous tongue may inform us that the disease is 
typhoid and not typhus. The stools are light ochre-coloured, 
and the eruption appearing on the abdomen make it pretty 
certain. As the disease advances the tongue and lips crack 
and are more or less covered with little ulcers. If the fever is 
protracted these spread over the mucous membrane of the 
throat, but the virulence of the disease spends its force upon 
those glands of the intestines called Peyer’s patches, situated 
on the lower portion of the illum These inflame and ulcerate : 
all post-mortems demonstrate this It may be interesting to 
give the average ages of liability. The mean age of 1772 cases 
admitted into the Fever Hospital, London, during ten years 
was as follows One half were between 15 and 25: one fifth 
under 15, less than one seventh were above 30, and less than 
one sixtieth exceeded 50 The mortality, which is not given, 
sometimes 1s very great. the approximation is one third. 
There 1s one peculiar fact, that typhoid is more prevalent 
among the nch and fortunate than the poor in proportion to 
their numbers Carrying the distinction of these two 
forms of fever to a fatal end we find that in typhus it is 
generally preceded by deep sleep. torpor, or coma, about the 
fourteenth day. while typhord, by extreme debility about the 
fourth week. This 1s the rule, the exceptions are may. 
TREATMENT —On account of the want of success in 
treating this disease 1n the past, some doctors have affirmed
