DR. CARPENTER’S RESEARCHES ON THE FORAMINIFERA. 
enabled to forward from time to time, regarding those other typical forms of Fora- 
minifera of which 1 have made a special study, it is not my intention to do more 
than state the results ; hoping that they may be understood to have been attained by a 
method of inquiry as closely resembling that which I have here followed through its 
details, as the circumstances of each case may have admitted. 1 would have it borne 
in mind throughout, that, as has been admirably remarked by one of the most accom- 
plished Botanists of our time, “the Naturalist who has the true interest of science at 
heart, not only feels that the thrusting of an uncalled-for synonym into the nomen- 
clature of science is an exposure of his own ignorance, and deserves censure, but that 
a wider range of knowledge and a greater depth of study are required, to prove those 
dissimilar forms to be identical, which any superficial observer can separate by words 
and a name” (Dr. J. D. Hooker, op. cit. p. 14, note). 
EXPLANATION OF THE PLATES. 
PLATE IV. 
Structure of the Animal of Orhitolite. 
Fig. 1. Entire Animal, from a small and simple disk, the shell having been removed 
by maceration in acid ; in the peripheral portion the segments of sarcode 
are wanting, and the structureless residuum of the shell is alone seen: — 
magnified 40 diameters. 
Fig. 2. Appearance of a portion of Sarcode, highly magnified : — 180 diam. 
Fig. 3. Portion of the body of one of the more complex forms (resembling fig. 4), in 
which the sarcode has broken up into little spheres (gemmules?); — a, a, 
superficial segments ; b, h, annular band : — 180 diam. 
Fig. 4. Portion of the body of one of the more complex forms, as seen in vertical 
section ;—aa, a'a', upper and lower rows of superficial cells, each cell con- 
nected, at its two extremities, with the annular bands hb and b'V of two 
zones; from these annular bands spring the columnar segments cc, dd, 
those of the sa?ne zone occasionally passing into each other, and commu- 
nicating with those of the next zone by oblique peduncles alternately pass- 
ing towards one side and the other: — 150 diam. (N.B. This figure is 
somewhat ideal, being made-up from several preparations ; but for every 
point which it represents, these preparations give warranty.) 
Fig. 5. Nucleus and first two annular zones, exhibiting the typical conformation; — 
a, the central segment; Z/A, the circumambient segment, from the entire 
margin of which are given off peduncles of sarcode, which give origin to 
the first annular zone : — 84 diam.
