Of the 1903 sections, Section I. forms a line running north-eastward 

 nearly along the centre of thejFaeroe-Shetland Channel. It is extended 

 northwards by the use of two of the International stations, the data 

 being extracted from the Bulletin. The dates of the observations are :

So that they may be regarded as fully comparable. 



Section II. is the same as Section I., except that it begins at 

 Station F4, more to the westward. 



Section III. extends practically from the Faeroe Bank to oft the 

 Flanuan Isles, right across the southern entrance of the channel. 



Section IV. is roughly parallel to Section III., but farther north, 

 beyond the Wyville-Thomson ridge. It begins on the Faeroe Bank, 

 but ends at Station F9, in mid-channel. 



Sections V. and VI. are off the west coast of Ireland. The two 

 Stations, E15 and E16,are nearly east and west of one another ; hence 

 Section V. gives some idea of the changes of distribution from the sea 

 towards the land. Section VI. runs due north and south across the 

 shallow bank to the West of Ireland. The middle of the section almost 

 touches the 100-fathom line, and there is deep water at both ends. 



The Sections I., II., and III. for 1904 follow the three lines already 

 described. Section I. extends from the South- West of Ireland to the 

 Azores, Section II. from the Azores through the Straits of Gibraltar 

 into the Mediterranean, and Section III. from a point (Station 38) 

 south of Cape St. Vincent to opposite the mouth of the English 

 Channel, in line with the International Station E4. Sections IV. and
