514 Sir george shuckburgh^s Obfervations 
made exprefsly in London and Paris, in order to make 
fuch experiments as might prefent themfelves to me en 
courranf, and which, either from want of acquaintance 
with the fubjedt, want of time, or want of money, be- 
come rarely the objedt of travellers; but remain wholly 
unknown till princely munificence and philofophic zeal 
(of which we have a recent inftance) unite in producing 
them to the world. After the very celebrated and inge- 
nious labours of Mr. de luc, farther inveftigation of 
the fubjedt of barometrical meafurement might feem 
unneceflary, if not invidious; but, furnifhed as I was 
with an apparatus every way fufficient for the inquiry, 
finding myfelf in the country which had been the fcene 
of his operations, and pofleffing fome fhare of his own 
zeal, I could not but gratify the euriofity I had to verify 
and repeat his experiments: if therefore in the purfuit 
of this inquiry I fhould be led to a conclufion fomething 
different from the- refult of his own obfervations, I am 
convinced that this diftinguilhed obferver, of whofe 
candour and talents I have an equal opinion, will im- 
pute it wholly to a love for truth; as with me the 
precept applies as ftrongly to the philofopher as to the 
hifiorian, Nequid-falji audeat , ne quid veri non audeat 
dicer e.
