METHODS AND DATA, 11 



NOTES TO TABLE II. 

 Hauls marked with a f are not reckoned as " comparable." 



I regret to say that no bottles with the labels 22 c, 22/, 26 d, 35 g could be found when the collection 

 came to be sorted. They may have been thrown away at once and no record kept of the fact, or, I 

 tremble to think, have been mixed with an adjacent haul. One can infer from the recorded times of 

 hauling that in the case of 22 c and 22/ they can at most only have been mixed with 22 d, 22 e, or 22 y, 

 if the mistake was made at the time ; and as all are from the surface and at night, no gi'eat damage will 

 have been done. Similarly 26 d may have been mixed with 26 e, and 35 ^ with 35 h or 35 i. In these 

 two latter cases I think that they would eventually show up when the collections have been worked out. 

 In the meantime I can only plead that it is not easy for two men to keep nets going, sometimes for 

 twentv-four hours in the day, without making an occasional mistake. 



Another error was the labelling of a bottle 31 n, no such liaul having been made. From a series of 

 inferences unnecessary to detail, I believe this bottle to contain merely the conspicuous, separately- 

 preserved organisms of 32 n. It has been issued as 32 n', and will be treated in the percentages as a 

 part of 32 n. 



21 d, 21 d'. These were hauled at once, not towed : only part of the catch was preserved. 



22 c, 22 f. No bottles to be found with these labels. 



23 a. The net-mouth was very slightly open. This seemed to have occurred in the last few fathoms. 



owing to the rapid laying up of the wire at the end of the haul. 

 25 c. Stopped in the middle of the haul to put another turn on the drum of the engine-winch : collecting- 

 tin showed no visible life. 



25 d, 25 e. There is some doubt whether 25 e is not really a part of 25 (/. 



26 b. Owing to a collision in the middle of this haul, the net was open for about an extra twenty minutes. 



26 d. No bottle was to be found witli this label. 



27 a, 27 a'. Owing to a heavy swell, the net failed to close. 

 27 c. Collecting-tin contained no visible life. 



29 a, 30 a. Mesoplankton trawl. 



30 b, 30 c. Heavy rain and thunder overnight. 

 30 e. Mesoplankton trawl. 



32 k. The deepest haul in which anything was noticed to be alive. 



35 c, 35 <^. Nets fouled thermometer-wire : not all the catch was saved. 

 35^. No bottle was to be found with this label, 



36 e to 36 /. Open serial tow-nets.
