This Table shows that the total number of records of Sagztta for the six 
selected stations, and for the seven years, is four hundred and five, being 
somewhat fewer than the number of records of Calanus, but considerably 
in excess of the number of records of any other of the species that have 
been referred to. In making an analysis of the Table, it is found that 
while there is a considerable difference between the number of records for 
Station IV. and that for Station VIII., if the three inner stations and 
the three outer stations be considered separately, the difference in the 
numbers of each group is much less. These points will be made more 
evident by arranging the stations and the number of records for each as a 
formula, thus -— 
Formula (1) shows the number of records of Sagitta for each of the 
six selected stations :—

The numbers for the three outer stations are nearly equal, but Station I. 
in the other three shows a greater divergence. It may also be noticed that 
Station J. and Station VIIL., that have the highest number of records in 
each of the two groups, are intermediate stations—that is, Station I. is 
situated between Stations III. and IV., and Station VIII. between 
Stations V, aud IX. Moreover, if a comparison be made of the total
