Biy watch what time they would require to 
produce a fimilar effefl. In fourteen minutes 
the milk was curdled, and, what was remark- 
able, it had no bad tafte. This fac9: fupplied 
me with as ufeful hint. It told me, that in 
the courfe of my journey I might fpeedily and 
whenever I pleafed have new cheefe ; and the 
difcovery was of too much importance to me 
not to take advantage of it. During my firft 
€Xcurfion a fortunate incident of a like kind 
had fupplied me with butter, my milk having 
been changed into that fubftance merely by the 
jolting of my carriage. From my cows and 
my (he-goats I fliould now be able to procure, 
without difficulty, butter, cheefe^ and whey. I 
carried with me^ therefore, four of the bowls, 
which ferved me during my whole journey. 
They did not, indeed, retain their virtue in its 
full force 5 after four or five months it dimi- 
nifhed, and the milk was curdled more flowly ; 
there were times even, according to the degrees 
of temperature, when the effed: was not pro- 
duced in lefs than five or fix hours ; but it was 
fure to take place, and did not entirely ceafe till 
the end of fix or feven months. The veflels, 
however, never loft their difagreeable marine 
tafte.
