Part TIL — Fifteenth Annual Report. 



Physical Investigations. 



In addition to the regular determinations of the temperature and 

 density of the sea water at various stations by the ' Garland,' 

 special physical investigations were made last year in the Faroe- 

 Shetland Channel and in Loch Fyne. By the courtesy of Admiral 

 Wharton, the Hydrographer to the Admiralty, a series of tempera- 

 ture observations were taken in the former area by the officers of 

 H.M.S. 'Research,' under the command of Captain Moore, and a 

 large number of samples of water were secured from various depths 

 for the subsequent determination of the density. Mr H. N. 



p. 2S0. Dickson, F.R.G.S., has prepared a special report on the subject, 



which is printed in the present Report. The work was undertaken 

 with the view of forming part of the continued hydrographic survey 

 of the North Sea and the North Atlantic instituted as an interna- 

 tional scheme with Sweden, Denmark, Norway, and Germany in 

 1893, and the observations made on board H.M.S. ' Research' form 

 an important contribution to the subject. The observations in 

 Loch Fyne and the Firth of Clyde were made by Dr IT. R. Mill in 



p. 262. April and September, and are dealt with in a paper in the present 



Report. They serve to confirm the previous conclusions as to the 

 circulation of the waters in Loch Fyne. 



We have the honour to be, 



Your Lordship's most obedient servants.
