When analyzed, the foregoing tables, which in general bear each 
other out, show that we may separate the catches into three classes, 
rich, fair, and poor. The first, which I limit arbitrarily to stations 
where the volume of the quantitative catch was three or more cubic 
centimetres, and the number of copepods ninety or more in every 
three cc. when diluted to 150 ce. with water, includes Stations 2, 4, 7, 
8, 22, and 25; the second, with quantitative hauls of one to three cc., 
and ten to ninety copepods, Stations 11, 15, 25, 28, 31, 36, 38, 43; the 
third, with quantitative haul less than one ce. in bulk, and less than 
fifteen copepods, Station 35. These classes agree fairly well with 
the volumes of the qualitative (four-foot net) hauls, as is shown by the 
following table, the stations in italics being the ones at which quantita- 
tive hauls were made.
