What conclusions may now be drawn from these facts? 
1. That these animals seldom appear in the North Sea, between 
Great Britain, France, Belgium, the Netherlands and Denmark 
(141, 142, 143); that they don’t frequent the Baltic Ocean since 
two centuries; that they seldom appear in the so-called Skagerrak 
(85, 86, 87, 88, 89, 1114); rarely show themselves in the Gulf 
of Mexico (106 a) or in the Mediterranean (148); but that they 
moreover inhabit the whole of the Atlantic Ocean. 
2. That, when they remove their quarters, they seem to swim 
as much as possible in the so-called warm ocean-currents. The 
number of appearances, it is true, is very small, but surveying 
the foregoing list of appearances in the different months I am inclined 
to think that these animals in their migration from north to south 
really swim agaist the current, while, on the contrary, in their 
migration from south to north they move with the current. Only 
a very few times they were met with in the so-called cold ocean- 
currents. 
3. We observe that in the month of August some individuals 
reached the highest northern latitude, i.e. 70 degrees, and that a 
series of appearances took place from 70° N. to 41° N. latitude, 
— that in the month of September they seem not to appear be- 
yond 59° N. latitude; and so on; —so that we may conclude that 
in the beginning or in the middle of Augnst they have reached 
their most northern point and begin to migrate towards the south, 
as in December we read of no appearances beyond 41° N. latitude , 
and in January of no one beyond 19° S. latitude. And further we 
conclude that they seem to leave the southern hemisphere to mi- 
grate again towards the north already in January, for in February 
they generally have already reached the northern latitudes , in March 
still higher, and so on.
