XIII. Qbfervations on the milky Appearance, 

 of fome Spots of Water in the Sea \ by 

 the Same. 



Read March 12, ~r T has been remarked by feveral nayl- 

 JL gators, on their parTage from Mocha 

 to Bombay, Surat, &c. that they had difcovered in 

 the night fpots of water as white as milk, and could 

 never affign any reafon for it ; and many have been 

 fo much alarmed, that they have inimediately hove 

 to and founded ; but I never heard of any body ever 

 getting ground. In my paflage acrofs thofe feas in the 

 Kelfall, I difcovered all of a fudden, about 8 o'clock 

 in the evening, the water all round me as white as 

 milk (intermixt with flreaks or ferpentine lines of 

 black water). I immediately drew a bucket of it, and 

 carried it to the light, where it appeared juft as other 

 water ; I drew feveral more, and found it the fame: 

 fome I kept till the next morning, when I could per- 

 ceive no difference from that alongfide. We had run 

 by the log 50 min. from the time we firft obferved 

 it till daylight, and during all that time the water con- 

 tinued white as milk, but at full daylight it was of 

 its ufual colour. The next evening about 7 o'clock 

 the water appeared again as white as before; I then 

 drew another bucket and carried it to a very dark place, 

 and holding my head clofe to the bucket could per- 

 ceive.
