fubjedt to coniiderable errors ; the concurrent tefti-

no doubt about the main point ; and, that the errors 
might be as fmall as polftble, I have not only en-

to be had, I have always taken a mean amongft them. 
In many of the accounts, the relaters fay only be- 
tween fuch hours, or about fuch an hour: of this 
kind were the accounts of the times of the agitation 
of the waters at The Hague and Lochnefs, which 
vary the moll from a medium of the reft, the former 
erring about feven minutes in defedt, and the latter 
about twenty minutes in excefs ; with regard to 
the latter, however, I mull obferve, that, from the 
account itfelf, it is probable the agitation happened 
fooner than eleven o’clock, which is the time men-

of the fuperincumbent mafs, and not to its elafticity, mull produce 
this effect in fome degree; it is probable, however, that this could 
make no great difference, as the motion feems to have been very 
little retarded in its paffage from the original fource toAdadeira, to 
which place, I fuppofe, it muff have paffed under deeper feas than 
would be found in its road to Scotland.
