laws of heat, that obtain in the different regions of the 
atmofphere ; the effedts of moifture, winds, the eledfric 
fluid, together with the weight and qualities of the air in 
different countries* &c. ; that at the fame time that I am 
congratulating the prefent age on one of the molt bril- 
liant difcoveries in natural philofophy, I may be under- 
flood alfo to encourage every lover of fcience to flill farther 
enquiries in a branch of knowledge no lefs ufeful than 
ingenious; particularly in a kingdom wherein, from its 
commercial interefts, and in confequence its many inland 
navigations, every improvement in hydroflatics, the art 
of levelling, or geometry, cannot but tend confiderably 
to the public benefit. The fources of fcience are not 
eafily exhaufted;. multitudes of then? remain wholly 
unexplored. If novelty can afford a charm, the path I 
am fpeaking of, till of late, has been the leaft frequented ; 
witnefs the frefh, important truths in Pneumatical re- 
fearches that, from zeal and fafhion, every day’s expe- 
rience affords. I might here offer too a tribute of applaufe 
(and am fure in concert with this whole affembly) jufliy 
due to the indefatigable labours of him whole fleps I 
have purfued ; but I arn convinced he will rather hear 
me acknowledge our obligations to the ancients than any 
panegyric of himfelf. Be the benefit we receive from 
them our encouragement to proceed.
