MISCELLANEOUS JBSS AYS: 
‘Bate complaint, which phyficians 
have in vain laboured to account for, 
have originated trom this fource? 
Buiter is found very frequently to 
occafion much diforder to very 
weakly, delicate, and irritable fto- 
-machs; yet thefe {tomachs will bear 
olive-oil. This cannot eafily be ac- 
counted for, but from metallic im- 
pregnation. , 
I will not contend that all the ill 
effects attributed to butter are cauf- 
ed by the mineral particles which it 
gains by the means before fiated: I 
only infift that it is poffible, and in- 
deed very probable; and that, when 
butier is free from thefe particles, 
it is not fo unwholefome as fome 
have afierted; though, when it does 
contain them, it is feund to diforder 
very tender perfons. 
To enlarge upen the fubject, or 
attempt to explain the many ways 
by which a very {mall quantity of 
the above metals may prove inju- 
rious to the human frame, in fome 
particular conftitutions, would be 
only to repeat what has already been 
faid by abler writers*. Some will 
perhaps fay, that my ideas are very 
far-fetched; and others, that my opi- 
nions are ill-founded; but, J truti, 
whoever has read the induttrious 
Refearches of Sir George Baker on 
the Effeéts of Lead, and the melan- 
choly cafe of a young lady who di- 
ed in confequence of eating pickled 
famphire very {lightly impregnated 
with copper, and which others ate 
without being difeafed, as related 
by Dr. Percival, will receive my 
opinions with lefs objection. If I 
have erred, [ have done it in ho- 
nourable company,

I-fhall be very glad if the forego- 
ing obfervations have fufficient in- 
fluence on the dairy-men to indwce 
them to change their utenfils.. Ve-; 
ry commodious veffels may be mace 
of caft-iron, equally well ftied for 
the purpofes of the dairy, which 
will not-be expenfive, and will be 
more innocent and cleanly.

On the Ancient and Modern Navigation 
of India. From Dy. Vincent's Foyage 
of Nearchus, Ato. ' 
CANNOT take. a final leave of 
this coait without obferving, that, 
the whole diftance from the Indus, 
to Cape Jafk comes out as near as 
may be, fix hundred and twenty-five 
miles, equal to the eftimation, of Ar- 
rian on the coaft of the l&thyopha- 
gialone; and this number of miles 
Nearchus was from feyenty to fe- 
venty-five days in pafling. If, how- 
ever, with due allowance made for 
fetting out againft the monfoon, 
and twenty-four days loft at Care 
Monze, we reduce the whole to | 
forty days, we may form acompara- 
tive view between ancientand mo- 
dern navigation ; for it appears from 
the journal of the Houghton Eaft 
Indiaman, that the made the fame 
run in thirteen days; and upon her 
return was only five days from Go- 
meroon to Scindy Bar. But fo far 
is this from diminifhing the credit of 
the firft navigators, that it is‘enhanc- 
ed by every difhculty they had to 
furmount :—weak veffels with inex- 
perienced mariners; no provifions 
but fuch as an unknown coait might 
furnith; uo convenience for fleep-
