458 Dr. W. B. Carpenter on Eozoon canadense.

 pi. iv. fig. l,f?, and N. ohtusa, pi. vi. fig. 13, c, — the figure 

 given above being copied from a portion of the third of those 

 just cited, that I may not be charged with having " con- 

 structed" it. 



Thus, so fai* from Mr. Carter's case of utter {ncompatihility 

 proving fatal to the Foraminiferal doctrine of Eozoon, a " com- 

 parison of the actual specimens " (his own test) gives to that 

 doctrine the additional support of a very striking conformity. 

 Speaking for once in Carterese, I might say that Mr. Carter 

 has " found a mare's nest." 



Professors King and Rowney, also, in their anxiety to put me 

 in the wrong as regards the Foraminiferal relations of ^o.3oow, 

 have only betrayed their own ignorance of Foraminiferal 

 structure, to a degree that must (I should think) shock even 

 their ally Mr. Carter. " We have shown," they say (p. 393), 

 " that the relative position of two superposed acicular layers 

 (an ujiper and an under ' nummuline wall '), and the admitted 

 fact of their component aciculas often passing continuously and 

 without interruption from one ' chamber-cast ' to another, to 

 the exclusion of the ' intermediate skeleton,' are totally in- 

 compatible with the idea of the said ' nummuline layers ' 

 having resulted from pseudopodial tubulation." Now, putting 

 aside i\\Q first part of this statement, which betrays the con- 

 fusion existing in the minds of its writers between the true 

 " nummuline layer," as described by me from transparent 

 sections, and the " acicular layers " of decalcified specimens, 

 which may or may not represent it (see p. 461), — what must 

 be said by Mr. Carter of the second'^ For he, of course, 

 knows perfectly well that in the superposed whorls of Nummu- 

 lites, as described by me in 1849, and in the superposed layers 

 of Orhitoides, as described by him- 

 self in 1861, the pseudopodial tu- Fig- 2. 

 bulation normally passes on " con- a - 

 tinuously and without interruption 2 — 

 from one chamber to another, to 

 the exclusion of the ' intermediate 3 - 

 skeleton.' " This is represented 

 alike in my original figures of the 

 . "Nummuline tubulation" (Quart. Vertical Section of co-
