Many of these lochs are nearly as salt as the ocean. The surface 
densities observed in Locli Creran were taken after an abnormally heavy 
rainfall, and can scarcely be viewed as normal. The water was so 
fresh on the surface that there was an entire absence of marine pelagic 
forms in that zone, the tow-net only showing coniferous spines and 
other portions of plants. These observations excepted, in only other 
four instances did the specific gravity observations of surface water fall 
below 1025-0. In Loch Scridain, in the neighbourhood of Kilfinichen 
Bay, and in Loch Sunart, opposite Borrodale, the density recorded was 
1024-1 ; but in the latter this was after the admixture of rain. At 
Loch Harport, too, opposite Carbost Distillery, the low specific gravity, 
1024*5, was due to the rainfall augmenting the volume of the stream 
which there empties itself into the loch. At Tobermory, the specific 
gravity opposite the pier was as low as 1024-8. 
While these were the lowest specific gravity observations, the highest 
was recorded 3 miles to the west of the island of Rum, where the 
surface showed a density of 1028 2. All the others, both at surface 
and bottom, were under 1028*0. The surface densities of 1027-0 and 
upwards, in addition to those mentioned, were 1027*5 in Canna Harbour, 
1027-5 in Laig Bay, Eigg, and 1027-0 off Gometra, with Stalfa bearing 
south-west. Rome, therefore, of these lochs during a part of the summer of 
1890 were as salt as the neighbouring open sea. Lochs Aylort, Harport, 
Greshornish, and vSnizort, north of Ardnaraurchan, and Loch Tarbert in 
Jura, Loch Killisport in Argyleshire, and Loch Gruinart in Islay, are 
included in this number. In all of these, the communication with the 
oceanic waters wfis direct, and the water of eacli loch was readily renewed 
from the ocean. Loch Snizort might bo described as a p(U*tion of the 
Minch, and Loch Greshornish opens into Loch Snizort. Lochs Aylort,
