On some of the most important chemical discoveries made within the last two years
Journal of the Franklin Institute
Important Chemical JDiscoverles. 257 1"0362, respectively. The last is the highest observation (well authenticated) on record, with the exception of Captain Harrington's 1"0442 to the southward of Australia. The paper concludes with the following short summary of results: In conclusion, the result of the whole inquiry serves to show that the ehie]'differenees in oceanic specific gravity arise from local or special circumstances. It is highin regions where evaporatien is rapid, as in the
... , as in the trade-winds, and low in those parts of the ocean where much rain falls. It is highest of all (on the average) in arms of the sea, such as the Red Sea, where there are no rivers and but little rain ; and lowest near the mouths of great rivers, such as the St. Lawrence or the Plate, or in seas like the Black Sea and the Baltic, where the accession of fresh water is great. It is low also in high latitude in the vicinity of ice. The highest surface temperature anywhere recorded is 94 ° in the Red Sea near Aden. The highest surface temperatures recorded elsewhere* are 88 ° and 89 °. These have been found not unfrequently in the Indian Ocean near the Equator. Captain Maury speaks of a temperature of 95 ° as being not uncommon in the Red Sea, but there Is no record here of any temperature above 94 °.
