I have been the more copious in my account of the 
work before us, as the fubjed of it is very intereft- 
ing; one, in which fome of our brethren have re- 
markably diftinguifhed themfelves, which occalioned 
Dr. Springsfeld to dedicate his performance to this 
learned Society. The experiments in his work, of 
which there are many, are well devifed, and to ap- 
pearance carefully executed. He has not attempted 
to amufe us with vain and fruitlefs lpeculations but, 
on the contrary, has nobly turned his thoughts to- 
wards obviating the diftreffes, and relieving the mi- 
feries, to which human life is unhappily fubjed.
