tnerefore I sent my paper on Amoeba princeps to the press with 

 /the few allusions which it contains to what Dr. Wallich had pre- 

 / viously published on A. villosa. 

 / As to this paper conveying the impression that " every one of 



/ the characters peculiar to the Amcehce of which Dr. Wallich wrote 

 had been or were "for the first time" brought to notice by 

 myself (p. 115, vol. xii.), that I have not been "just" to 

 Dr. Wallich [ibid.), and that I have "assailed directly or in- 

 directly nearly every opinion and statement " that he has made 

 in the communications under reference (p. 151), I certainly do 

 not think that my paper calls for any such expressions, and, 

 without defending myself in long explanatory notes which no one 

 would read, am quite content to receive the verdict which those 

 acquainted with the subject may be disposed to give after reading 

 Dr. Wallich's and my own papers respectively in the ' Annals ' 

 for 1863, Nos. 64 to 68 inclusive. 



Dr. Wallich (p. 115) has completely distorted the application 

 of the term " nomenclature " as I have used it in the commence- 

 ment of my paper (p. 30). The passage runs thus : — " It may 

 be remembered by those who have read my ' Notes on the Orga- 

 nization of Infusoria, &c.-' [published in 1863] , that I have therein 

 proceeded upon a certain nomenclature of their parts generally ; 

 and I shall pursue the same course here in the description of 

 A. princeps specially." Yet, to read Dr. Wallich^s objections, it 

 would appear that I had used the word " nomenclature " with 

 reference to qncies. It was not until 1863 that I ever met with 

 A. princeps in such numbers as to be able to make so much out 

 of it as I have done of the other freshwater Rhizopods, viz. as 

 regards its " reproductive cells." And as in this paper the 

 Amoeba are not referred to generally, my remarks must be con- 

 sidered to apply to A. princeps specially, where it is not stated 

 otherwise. 



Of Dr. WalhcVs criticisms on my " Communications " on the 

 Infusoria generally previous to 1863, 1 must also leave the public 

 to judge ; and if I ever carry out my intention of writing more at 

 length on the subject, I shall then, in the general review of what 

 I have written since 1856 inclusive, hope to benefit by what my 

 friend Dr. Wallich has written in 1863.
