Part III — Seventh Annual Report 



physical investigation of sea water. The fitting up of part of the deck-house 

 as a little laboratory was this day completed. The various apparatus were 

 found to work very well on board ship, one or two slight modifications 

 being however found necessary. 



Tuesday, September 4. — A second trial trip was made in order to test 

 more thoroughly some modifications in the mode of working which re- 

 sulted from the previous day's experience. 



The trials made on this day were very satisfactory, so that although it 

 was necessary for me to be in Edinburgh on the 5th and 6th September, 

 I arranged with Lieutenant Farquhar that the ' Jackal ' should proceed 

 on the morning of the 5th to Broughty Ferry, en route for Aberdeen. 

 During my absence the conduct of the physical observations was entrusted 

 to Mr F. M. Gibson, who had had considerable previous experience in 

 similar investigations. I left with him instructions for a series of observa- 

 tions to be made in the Firth of Tay, and at two points along the coast 

 between Broughty Ferry and Aberdeen. Mr "William Boyd, of the Com- 

 mittee of Scientific Investigations, accompanied the expedition from 

 Granton to Aberdeen, at which place I rejoined the expedition on the 8th 

 September. 



Monday, September 10. — In the afternoon the 'Jackal' left Aberdeen 

 and proceeded to Peterhead, off which place a very short stay was made, 

 during which I was able to confer with Mr Boyd on some points relating 

 to the observations to be carried on. 



Tuesday, September 11. — About 8 o'clock in the morning, some observa- 

 tions were made between the Sutors near Cromarty and samples of water 

 collected (Stations XIII. and XIY.). No further stay was made before 

 reaching Kirkwall, Station XV., where a series of observations were made 

 at various states of the tide from the evening of September 11th to the 

 morning of September 13th. 



Thursday, September 13. — Observations were made at Stations XVI., 

 XVJLL, and XVIII. in Stronsa Firth. In the afternoon the 'Jackal' 

 anchored in Viera Sound, opposite Trumland, Brousay, Station XIX., 

 where another series of observations and analytical operations were carried 

 on. 



Saturday, September 15. — We proceeded to Lerwick, stopping at 

 Station XX. in Eda Sound. The 'Jackal,' after experiencing a somewhat 

 rough passage, passed Sumburgh Head at 2.10 p.m., and came to about 

 4 p.m. the same afternoon in Lerwick Harbour, where she remained over 

 the two next days. Here again serial temperature observations w^ere 

 made at regular intervals (Station XXL), and a number of analytical 

 operations gone through. 



Tuesday, September 18. — Observations were made at Station XXII,, 

 off Noss Head, and Station XXIIL, off the Out Skerrie Lighthouse on 

 the way to Balta Sound, Station XXIV., where the ' Jackal ' remained at 

 anchor over night. Here also serial temperature observations, &c, were 

 made. 



Wednesday, September 19. — At about noon the 'Jackal' weighed 

 anchor and proceeded in a direct line eastwards across the North Sea 

 Favoured by splendid weather, a very successful series of observations 

 were made at Stations XXV., XXVI., XXVIL, and XXVIII. 



Thursday, September 20.— From Station XXVIII., situated about 20 

 miles off the coast of Norway, the course taken was up Fieosen, past the 

 entrance of Hielte Fiord, through Herlo Fiord, and By Fiord to 

 Bergen. Observations were made off the entrance to Hielte Fiorde and 

 in By Fiord (Station XXIX. and Station XXX.) At about 4 p.m. the 

 'Jackal' anchored off Bergen where she remained three days.
