than far off the coast: lO" and iio are generally only met with at the 

 station nearest land: in Figs. 2 and 3, 90 is not reached at the outer- 

 most stations. It is also most striking that the nearer the Skagerak 

 and Christiania Fjord is approached (Ekersund Section, Station 18), the 

 greater is the maximum temperature (no, 120), whilst Fig. 3, the northern- 

 most section, shews a maximum of but 90. If one regards this maximum 

 as resulting from the high surface temperature of the Summer months, 

 which has gradually gone cjownwards in the deep, the above conditions 

 are thereby naturally explained through the Baltic Current, as previously 

 mentioned, having a higher temperature in the Skagerak and the Christi- 

 ania Fjord than on the West Coast of Norway; and the circumstance 

 that the autumnal maximum is greatest near land, has than its origin 

 in the Baltic Current of great depth, flowing along the Norwegian 

 coast. To what extent this explanation is right, or the only one, 

 I dare not at present decide, as other conditions may, likewise, be 

 imagined to have some influence. That the pasl S?(mme/ s Baltic Current 

 plays a part in the temperature conditions during the Autumn, appears 

 to me, at all events, to be certain. The very great difference between 

 the temperature of the thin Baltic layer, and that of the Bank Water, 

 Station 18, is peculiar. The surface exhibits a temperature of 4. 30, 

 while only 6 mètres down it is as much as 11.20. The Baltic Curreftt 

 is then, therefore (by the influence of the air, and addition of river 

 water) greatly coolled, whilst the Bank Water even than retains a portion 

 of its Summer warmth. 



In the deep, the temperature below the maximum falls evenly; at 

 the deepest spot (Ekersund section), 345 mètres deep, down to 5.30. 

 For the rest the reader is referred to the figures. 



T/ie Atitumn of 18 g4, varied greatly from that of 1893. The Surface 

 Chart of November 1894 (C), shews one that the Baltic layer had a far 

 greater diffusion than in the previous year. Whilst, in November 1893, 

 the Baltic Current was dammed up in the Skagerak and Cattegat, in 

 November 1894, it flowed along the whole of our West Coast, at many 

 places having a breadth of 16 to 20 miles. On the other hand the 

 Bank Water was of far less thickness. The saltest layer of the Bank 

 Water was first found on the surface far off the land. Neither did the 

 Atlantic Water advance so far as during the previous year, more 

 especially jiot on the southern portions of the West Coast, whilst, further 

 North, it come in nearer to the land. 



It would have been of great interest had the conditions in November 

 1894, permitted a similar investigation of the Norwegian Channel as
