Britain,” cites the following cases: (1st.) 20 out of 22 boys at 
a certain school were seized with fever, accompanied by 
gastro-intestinal irritation. Two of the fatal cases were 
examined, and theusual lesion of Peyers’ glands—(these glands 
of the intestines were first discovered by an anatomist named 
Peyers)-—was discovered. The cause was attributed to the 
opening two days before of a drain at the back of a house 
which had been choked up for many years, and the 
distribution of its offensive contents over a garden adjoining 
the play-ground of the boys. (2nd.) In 1835 an epidemic of 
enteric (typhoid) fever desolated the district of Auvergne, 
nearly half of the inhabitants were affected and about one 
third died. The cause was traced to a stagnant pool which 
was a receptacle for dead animals and the sewerage of the 
district. ‘Three times did the pestilence return, and each time 
the wind was blowing over the affected water (3rd.) All the 
residents in a farm-house in Peebles, 15 in number, were 
seized with a fever accompanied with so much gastro-intes- 
tinal trouble that suspicions of poisoning were entertained 
Three of them died The only explanation of the outbreak 
was that all the drains in the vicinity of the house were 
choked up and obstructed with the accumulation of filth from 
privies and the farm-yard In these cases we have a clear 
evidence of the origin of the disease% It is a matter of 
dispute as to its being infectious from person to person, the 
Opinion is, however, almost unanimous now that it is Some 
affirm that it is caused by alvine discharges of typhoid 
patients. About five years ago a terrible visitation swept 
away thousands in and around Plymouth (America) The 
cause was traced to an infected person whose secretions 
found their way into the small river which supplies the district. 
It is well to know these things, as we see how to prevent those 
terrible visitations. The symptoms of typhoid fever are not 
So plain at the commencement as to make it certain even to 
the experienced, the incubation stage of most fevers being 
much alike; we may be guided by the fact of its prevalence 
(where it isso). Look well to the sanitary conditions present :
