Mr. W. Clark on the recent Foraminifera. 165 
stars we can observe their proper motions, but in those which are 
plunged in the deeper regions of the sphere, these motions, 
though we may presume that they undoubtedly exist, are inap- 
preciable. Why may we not apply a similar reasoning to the 
doctrine of the sensations or interior sentiment, and the resulting 
nervous and muscular influences, being implanted i in the lowest 
as well as the highly organized animals, according to their seve- 
ral structures, and not consign vast classes to exist without sen- 
sation? It appears to me that the lines of separation between 
apathy, sensation, interior sentiment, and intelligence, as laid 
down by Lamarck, are erroneous and arbitrary. I believe that 
apathy in its strict sense, as applied to animals, does not exist ; 
and I repeat, that the most inferior created animal being is not 
without that portion of sensation or interior sentiment, and its 
concomitant nervous and muscular influence, that produces the 
motions which are the tests of vitality. I may state that Lamarck 
does not admit the distinction of intelligence and instinct ; he 
very justly considers the different degrees of what is called in- 
stinct, in animals, as only subdued intelligences consequent on 
their imperfect organs, when compared with the highest standard 
—man. 
There is a great gulf between the intelligence of the brute 
creation and that of man; the impassable line is, that the one 
does not fear death, and has no idea of the future, because the 
beneficent Creator has not given it sufficient intelligence to rea- 
son on matters which will never be granted ; but man fears death 
and ardently desires immortality, because his Maker has con- 
ferred on him the knowledge of life and death, and it may 
therefore reasonably be inferred, that we shall not be tantalized 
with a prospective view and hope of these things, if they were not 
to be accomplished. 
To return to the Foraminifera: I am inclined to think ia the 
major part of these organisms, whether straight, arcuated, dis- 
coid, alternate, enveloping, rolled en peloton, or whatever confi- 
guration they may take, will conform in all the essential gene- 
ralities with the structure of the animal—I mean of those parts 
of it which I have clearly determined in the Dentalina linearis 
and Marginulina legumen, and which I consider may fairly be 
constituted the type of that section of the calcareous Polypi 
termed Foraminifera: these organisms, from their distinct and 
separate growth, show an advance in organization that justly 
places them at the head of the calcareous Polypi, and I think it 
will be long before this assigned position in the progressive order 
of creation will be disturbed. That specialty-differences of a 
more or less decided character exist in the component parts of 
this group cannot be doubted; such variations are seen in every
