was taken notice of in our laft report. 
Fevers of the malignant kind have conti- 
nued to prevail, and have in feveral in- 
fiances proved fatal. 
Of the Scarlatina Anginofa there have 
been numerous inftances. ‘This difleafe is 
very common at this feafon of the year, 
and oftentimes affumes a more threaten- 
ing appearance than in the earlier months, 
‘It is generally introduced by a greater or 
lefs degree of chillinefs and fhivering, 
which is {icceeded by a fenfe of fullnets 
and uneafinefs about the throat. Deglu- 
tition foon becomes diificult, and this cir= 
cumftance, particularly in children, pre- 
vents the taking in a prope: quantity of 
any kind of nourifhment. A ficarlet erup - 
tion is foon difcovered upon the fkin, 
which in a few days difappears, and the 
fever frequently fubfides at the fame time. 
In two of the patients referred to in the 
lift, there was a confiderable difcharge 
through the nofe of an acrimonious and 
offenfive matter. In both of thefe there 
was alfo a confiderable tumour on each 
fide of the neck. ‘This fymptom, as we 
are informed by other praétitioners, has 
very frequently attended this difeafe at 
the prefent feafon. 
The fmall-pox ftill continues to {pread 
in the metropolis and its environs, and in > 
many cafes has proved confluent and fatal. 
Rheumatic affections of the head and 
face fiill continue to form a large pro- 
portion of the chronic difeafes of the pre- 
fent feafon. They have proved very ob- 
ftinate in many inftances. In fome pa- 
tients they have been connected with 
fymptoms of fever; flight fhiverings have 
been fucceeded by an increafe of heat, 
guicknefs of pulfe, and other febrile 
fymptoms. ‘This difeafe has fometimes 
put on the form of an intermittent, either 
of the quotidian or tertian type, and has 
been treated moft fuccefstully by a free 
wis of the cortex.
