dental symptoms, to which we may apply appropriate remedies 
when they appear, than to pass over in silence the characteristic 
symptoms. 
I have remarked with Barrier, that the constitutional disturb- 
ance preparatory to the appearance of the eruption lasts during 
five or six days, and is common to a great many diseases. They 
are loss of spirits and appetite, dryness of the mouth and muzzle, 
heat of the skin, frequency of the pulse, staring of the coat, 
shivering, vomiting, discolouration of the urine, and constipa- 
tion. 
The essential symptoms succeed in the following order. The 
skin of the belly, the groin, and the inside of the fore-arm becomes 
of a redder colour than in its natural state, and sprinkled with 
small red spots irregularly rounded. They are sometimes isolated, 
sometimes clustered together. The near approach of this erup- 
tion is announced by an increase of fever. 
On the second day the spots are larger, and the integument 
is a little tumefied at the centre of each. 
On the third day the spots have enlarged, and the skin is still 
more prominent at their centre. 
On the fourth day the summit of the tumour is yet more pro- 
minent. Towards the end of that day the redness of the centre 
begins to assume a somewhat grey colour. On the following 
days the pustules assume their characteristic appearance, and 
cannot be confounded with any other eruption. On the summit 
is a white circular point, corresponding with a certain quantity 
of nearly transparent fluid which it contains, and covered by a 
thin and lucid transparent pellicle. This fluid becomes less and 
less transparent, until it acquires the colour and consistence of 
pus. The pustule during its serous state is of a rounded form. 
It is flattened when the fluid acquires a purulent character, and 
even slightly depressed towards the close of the period of suppu- 
ration, and when that of desiccation is about to commence, and 
which ordinarily happens towards the ninth or tenth day of the 
eruption. The desiccation and desquamation occupy an exceed- 
ingly variable length of time, and so, indeed, do all the different 
periods of the disease. What is the least inconstant is the dura- 
tion of serous eruption, which is about four days, if it has been 
distinctly produced and sheltered from all friction. If the cha- 
racter of the pustules is considered en masse, it will be observed 
that, while some of them will be in a state of serous secretion, 
others will only have begun to appear. 
The eruption terminates when the desiccation commences in the 
first pustules ; and if some red spots should shew themselves at 
that period of the malady, they disappear without being followed 
by the development of pustules. They are a species of aborted 
pustules. After the desiccation of the pustules, the skin remains
