proceeds :—‘It is for the Lamarckians to explain how it hap- | 
pens that these same savages of Borneo have not themselves © 
acquired, by dint of longing, for many generations, for the 
power of climbing trees, the elongated arms of the orang, or 
even the prehensile tails of some American monkeys. Instead 
of being reduced to the necessity of subjugating stubborn and 
untractable brutes, we should naturally have anticipated ‘that ~ 
their wants would have excited them to efforts, and that con- | 
tinued efforts would have given rise to new organs :” or, rather, © 
to the reacquisition of organs, which in a manner irreconcil- — 
able with the principle of the ‘“ progressive” system, have — 
grown obsolete in tribes of men which have such constant need ~ 
se 
of them.’*

Some of Lamarck’s characteristic and assailable illustrations - 
have indeed been adopted and further developed :—‘ Ceux des 
mammiféres aquatiques qui contractérent Vhabitude de ne 
jamais sortir des eaux, et seulement de venir respirer a leur sur-_ 
face, donnérent probablement lieu aux différens Cetacées. En 
effet, depuis l’énorme quantité de temps que ces animaux vi-— 
vel 
leur servoit de soutien et d’attache.t As a fact, however, so 
uch of the pelvis has been preserved in Cetacea as serves to 
‘win adds another consideration to ac- 
count for the enormous head in Cetacea :—‘In North America | 
the black bear was seen by Hearne swimming for hours — 
with widely open mouth, thus catching, almost like a whale, 
insects in the water.t I see no difficulty ina race of bears —
