CONCLUSIONS. 5A] 
Malacca Straits (146), and March in Geographe Bay (150). 
In May it was observed south of Australia (122), and in April 
south of Kiu Siu, Japan (151). 
. A few lines above I have already expressed my firm conviction 
that they are migratory and don’t like cold water. If this be true, 
they will be generally observed (and I purposely draw the reader's 
attention to the expression “generally”, for animals are not bound 
by /aws of nature), in the northern hemisphere when summer is 
there, and they will generally appear in the southern hemisphere 
when summer visits those parts of our globe. To follow this rule 
they must be able to migrate from north to south, and vice versa. 
Consequently the Atlantic and the Pacific are the only two oceans 
in which we shall observe that generally this rule is followed, for 
in the Indian Ocean the animals are checked in their course towards 
the north by the continent of Asia. 
We are therefore obliged to take no account of the appearances 
which occurred in the Indian Ocean. And as we have only two 
appearances observed in the Pacific, of which the dates are men- 
tioned, we are also obliged to pass over those in the Pacific too. 
Let us now see where the animals were met with in the different 
months.
