puzzling diversity, which indicates that further work is 

 necessary.* I hope to continue this work myself from a 

 small steam-yacht during the coming spring and summer. 

 In addition to the equipment previously used I have 

 recently obtained a Nansen closing deep-water tow-net with 

 which observations will also be taken. 



Dr. Travis Jenkins has recently arranged to permit 

 of the steamer taking periodic trips along a fixed line for 

 the purpose of obtaining gatherings with the large Hensen 

 quantitative net. These trips will take place monthly, 

 the line of stations is from Piel Gas buoy to the Great 

 Orme Head, and Mr. Scott will carry on the work. The 

 series was started in January, 1907, and the second trip 

 is now taking place. 



Hydrographical Observations. 



The scheme of hydrographic observations which was 

 proposed in the Introduction to the last Annual Report 

 was duly sanctioned by the Committee, the necessary 

 apparatus was obtained, and the practical work was 

 started in summer. The observations are carried out by 

 Mr. Johnstone on the steamer, and the samples of sea- 

 water obtained are analysed in the laboratory by Dr. 

 Basset, to whom we are very much indebted for the time 

 and trouble he is kindly giving to the work. It is too 

 soon yet to come to any conclusions, so I merely place on 

 record the following list of observations made : — 



Three cruises were made during 1906 : — 



(1) 4-5 July, 1906. 



(2) 18-19 Sept., 1906. 



(3) 13-14 Nov, 1906. 



* A fuller account of these observations was given in an address 

 delivered to the Biological Society, and published in the Annual 

 Report of the Liverpool Marine Biology Committee in December. I 

 do not repeat the information here because I am convinced that 

 further work is required and that I shall be able to give a better 

 account of the whole subject by waiting till next year.
