and north of latitude 45° nearly to 60°, where few, if any, 

 observations have been taken. Otto Pettersson and Cleve 

 in their recently published charts mark this region 

 " Okandt," and it is interesting to find that our two traverses 

 in the "Parisian" went right through the length of this 

 "unknown" region. Dr. John Murray made a traverse 

 of the North Atlantic in this part in 1892, but he tells me 

 that, although he gave some of the results in lectures at 

 Boston, he has never published the details of his work. 

 Consequently, we believe the present to be the first 

 complete account published of a continuous traverse 

 across the North Atlantic. 



List of the Gatherings, with the Organisms 

 Observed in Each. 



By W. A. Herdman, I. C. Thompson, and Andrew Scott. 



The outward gatherings are numbered from 1 to 17 

 consecutively in Arabic numerals, and each number 

 indicates what was gathered during one day or one night, 

 irrespective of the number of nets used and of the number 

 of bottles rilled. Where the contents of the different nets 

 were kept separate, the lists are marked (A), (B) &c. 

 The gatherings taken on the homeward journey are 

 labelled from I. to XXIY. in Boman numerals. In some 

 cases the nets at the tap and at the overflow pipe are 

 numbered separately. The gatherings taken from the 

 bath tap are marked A, B, C, &c. 



The latitudes and longitudes at the times of emptying 

 the nets have been calculated from the position of the 

 ship at noon each day on the assumption that the ship 

 ran equal distances in equal periods of time during the 24 

 hours.
