Have lost reference to Marsh and Marsh who quoted from Michael
Foster's TextBook of Physiology (1888): "The endothelium did not
escape his attention . . ." Does anyone know the Reference?

Dear popso,

I searched on the local University database to find this reference for
you.

A short history of nitroglycerine and nitric oxide in pharmacology and
physiology, by N. Marsh and A. Marsh. In CLIN EXP PHARMACOL, P 27 (4):
313-319 APR 2000.


They cited
Textbook of Physiology by M. FOSTER, 1888 

I hope this is what you needed
