very important purpofes in the ceconomy of young animals; and. 
that in proportion as the intention of Nafure is in thefe refpedts 
fruftrated, the effets will be more or lefs feverely felt. Would it 
be deemed a conjecture, exceeding the bounds-of probability, to 
fufpe&t that the avolation of a very large quantity of phlogifion, 
and its due feparation from the mafs of blood by pure air, may be 
effentially neceffary to the growth of young animals; and that 
this may be one reafon why the impure air of cities has, in all 
ages, been particularly deftrutive to their health? 
‘Wir a view of reducing the une day fits to its proper genus 
and fpecies in nofology, I have turned over the works of fome 
’ of our beft writers on this fubje@. The only genus to which I 
think it can with any propriety be reduced, is that of eclampfia 
or convulfion des enfans of Sauvages. But although under this 
generic title he defcribes feventeen fpecies, there is not one of 
them to which it bears an exact refemblance. The eclampfia 
neophytorum of Vander Monde is widely different, as any one 
may eafily fee by cafting an eye over the hiftory of both. As 
moft of the fpecies enumerated by Sauvages are fymptomatic, and 
as he has diftinguifhed feveral of them from various kinds of 
deleterious fubftances taken into the fyftem; as eclampfia ab 
atropa, cicuta, &c. perhaps we might with equal propriety add 
eclampfia ab atmofphezera phlogifticata. 
TueEre is a fporadic difeafe in Minorca and fome other countries
