fo very lingular, as to make it by fome gentlemen 
greatly doubted, on account of their imagining, that 
the degree of heat in melted lead was too great to 
be borne in the domach, without immediate death. 
cafe ; I herein can not only convince your lordlhip of 
its fad, by my own and (if requilite) the oaths of 
others, but alfo by the following experiments, which 
from limilarity of circumftances mull not only 
render that probable, but (in the mod convincing 
manner) the abfolute polfibility of my alfertion. 
I extracted in three pieces, from the llomach of 
a fmall dog, fix drachms one fcruple of lead, which 
I had pour’d dowii^^jicoat the day before. 
N.B. The the oefophagus feemed 
very vifcid, andltl^^^^i much corrugated, tho’ 
its internal coat excoriated. 
The dog had nom+ng^fo eat or drink after; nor 
for twenty-four hours before the experiment, when, 
being very brilk, I killed him. 
I alfo took from the llomach of a large dog (in 
feveral pieces) fix ounces and two drachms of lead, 
three days after thrown ip.
