168 Mr. W. Clark on the recent Foraminifera. 
believe, introduced into that genus by myself; the necks of the 
typical Nodosarie are strangulated, but generally so slightly as 
scarcely to detract from their strength, and are consequently 
usually found united. 
It has been stated that the rough sketch of Nodosaria levis, in 
my first paper on the Foraminifera, and which had no reference 
to the exact outline of that species, and was merely intended to 
illustrate the structure of this organism, has been mistaken by 
me for a Nodosaria, not the levis ; I therefore in decided terms 
state, that the mistake is not with me, and that the fragment 
which all authors constitute the Vermiculum leve of Montagu, 
alias their Lagena levis, is the true and identical object I have 
seen in a stem of two, three, and four united nodules with elon- 
gated necks. 
I exclude the family of the Miliolide, hitherto and perhaps 
correctly included in the Foraminifera ; I have them now under 
investigation ; and will at present only observe, that whatever 
their position may turn out to be, they are all inhabited by an 
internal animal, as my observations on the buccal pouches of the 
Dentaha sutticiently prove. 
I hasten to conclude with some remarks on the neglect in which 
this microscopic branch of natural history has long been involved. 
The causes that have prevented the due consideration of the ani- 
mals of the Foraminifera, and their singularly beautiful orga- 
nisms, are entirely owing to mistaken ideas of the difficulties at- 
tendant on their investigation, the acquisition of the objects, and 
the supposed injury to the sight by the use of high microscopic 
powers. ‘These objections I think I shall prove to be ideal, and 
if we apply the trite aphorism “‘ Omne ignotum pro magnifico ” 
to our case, we shall find that if we devote ourselves determi- 
nately to careful examination and investigation, all difficulties 
will soon disappear, and we shall be surprised at their simple 
solutions, because in many cases they have assumed the aspect 
of something miraculous, merely from being enveloped in the 
meshes of ignorance. 
The acquisition of these elegant objects, adorned with sculp- 
ture of surpassing beauty, presents no msurmountable difficul- 
ties ; every shore coated with sands has a certain line which is 
instantly perceived by the experienced observer, and will furnish 
a supply of the more common species, and the finer sands of the 
coralline zone, five or six miles from the shore, by the dredge, will 
afford abundance of the rarer species. There are also in certain 
districts marine deposits formed by the subsidence of the waters, 
which, though of great antiquity, still exhibit the freshness of 
recent origin without a trace of fossiliferous aspect. 
As to the sight being injured by a continuous examination of
