rOPULAR SCIENCE REVIEW. 
bably but a sea mare’s-nest, discovered by Professor Huxley, 
and appropriately named by him after his Herman alter ego ), 
sometimes into a ludicrously exaggerated estimate of the philo- 
sophical or theological consequences of elementary truths, e.g. 
those of development.” (Op. cit. p. 145.) 
Mr. Mivart has done me honour to mention in his list of works 
on the Radiolaria, published since the appearance of Haeckel’s 
monograph “Die Radiolarien ” in 1862, my “North Atlantic 
Sea-bed,” published also in 1862 ; my paper on “The Structure 
and Affinities of the Polycystina ,” published in 1865 ; and my 
“ Observations on the Thalassicollidce and Collosphoericlce” 
published in 1869 ; the remark being appended to the last 
notice that “ no mention was therein made of Haeckel’s mono- 
graph.” It may be allowed me, therefore, to point out that 
my “North Atlantic Sea-bed” was not , as alleged (indeed the date 
Mr. Mivart gives sufficiently attests this), issued after Haeckel’s 
monograph ; and that one reason alone deterred me from alluding 
to the latter in 1869 — a reason Mr. Mivart compels me now 
to divulge — namely, the desire to avoid giving utterance to an 
opinion upon Professor Haeckel’s method and the errors spring- 
ing out of his “fiery pantheism,” which, if expressed at all, 
could not have fallen far short of Mr. Mivart’s, or been so 
lightly formed as to become so soon forgotten. Besides, had he 
taken but a little more trouble in the perusal of my paper “ On 
the Polycystina ,” he would at once have seen that I therein, 
whilst referring directly to Haeckel’s monograph, did my best 
to explain, in most guarded and courteous language, my disin- 
clination to comment unfavourably on a method of building 
up a superstructure which appeared to me to be so full of 
danger. 
I feel, therefore, that the time has arrived for demonstrating 
the fallacy, on the one hand, of splitting up into a number of 
trivial groups, and genera, and species, an assemblage of or- 
ganisms so pre-eminently distinguished for an almost endless 
tendency to variation as the whole of the Radiolarian families ; 
and, on the other hand, of attempting (according to a system 
living specimen as seen with his own eyes. Those who desire to trace the 
history of the rise and fall of this prodigious fiction will find it in the 
following papers : — 
“ On the Vital Functions of the Deep Sea Protozoa,” by G. C. Wallicli, 
M.D., &c., “Monthly Micr. Journal,” January, 1869. 
“ On the True Nature of the so-called Bathybius,” by the same Author. 
“ Annals and Mag. Nat. Hist.’ for November 1875. 
“Deep Sea Researches — The Biography of Globigerina,” by the same 
Author. John Van Voorst, London : 1876. 
“ On the Coccosphere,” by the same Author. “ Annals,” Apr. 1877.
