'An Account of an Experiment of the hje&ion of Mercury 
into the Blood y and its ill Ejfetfs on the Lungs 5 as it 
was communicated to the Royal Society by their late toor* 
thy Member A. Moulin, M. D. 
IHave promifed laft Meeting to give my Reafons this 
day why I conceive Mercury to be an Enemy to the 
Lungs : I (hall only give an account of an Experiment I 
made on a Dog at Mr. Boyle's laft Autumn, which I take to

Bronchia, were only Blifters or a feparation of the com-

of thefe were larger than a £Louncival-Pea, others were
