IL A Letter from Mr, William Cowper, gimn^ 
an Accomt of a 'very Urge Difeafzd Kid'- 
ney-^ found on the DtffeSlion of a Lady^ r^ith 
the Symptoms of the Difeafe before her Deatb^ 
and an Explanation of their Phenomena. 
SIR, 
Qlfice you were pleafed to tdl me the Obfervations I 
^ lately had an opportunity of making, in Difled-iog 
a Morbid Body, would not be ungratetul to the R$jal 
Society, I have thought my felf obliged to recolleel the

Symptoms fome time before Death, which are com- 
monly taken toarife from other effeds, and may deferve 
our Confideration. 
The Subjed: of our prefent Obfervations was a young 
Gentlewoman not Married, who about eight Years be- 
fore her Death found fome fmall pains in the Lumbal 
Regions, and fometimes made blackifli Urine. If fee 
at any time ufed any Motion, the Pain would encreafe; 
commonly finding moft eafe when her Body was fe-
