I made a trial of the inftrument at this place, but 
having loft the flip of paper on which I had noted the 
experiments, I was dubious whether I fhould infert the 
above or not. I can only recoiled! thefe four, and am, 
not pofitive which way the index flood however, I re- 
member that the mean of all the obfervations I made 
was fomething Ms than 80°. Time will not permit me. 
to repeat the operation during the fhip’s ftay in thefe 
parts ; I muft therefore defer it to a future period. Du- 
ring the winter, I fhall have frequent opportunities of 
amuftng myfelf this way; and the refpedi I bear the 
Royal Society, makes every fervice I render to that il— 
luftrious body an additional happinefs to 
Their devoted fervant,.
