CORRESPONDENCE. 



Sowerby's "Mineral Conchology" — German and French Editions. 



I shall be extremely obliged if anyone can inform me of the date of issue of 

 the several parts of the two editions of Sowerby's " Mineral Conchology," published 

 by Louis Agassiz, between about 1839 and 1844. I have tried the usual sources, 

 and, beyond some scattered facts, have obtained little information. Professor 

 Alexander Agassiz, who possesses his father's own copies, tells me that they are 

 bound without the wrappers, and points out the curious indifference of biblio- 

 graphers as to dates in these early days, as Louis Agassiz himself must have been 

 sensible of the importance of keeping a record.

In his notice of ray " Ethnology " (Natural Science, August, 1896) the writer 

 charges me with stating that zoologists detach from the class mammals the apes 

 and half-apes, as if these animals were not mammals. This inference would have 

 been avoided had the reviewer quoted the concluding words of the sentence in 

 question : " they [the apes and half-apes] are the chief or most highly specialised 

 members of the class" (p. 17). I may not have "a scientific mind," as he says ; 

 but I trust I am not the lunatic I am here made to appear by the suppressio vevi et 

 suggestio falsi device. It would be well if those who pique themselves on their 

 " scientific mind " paid also a little attention to fair play and accuracy of quotation.

[The passage in question reads thus : " Zoologists detach from the Class 

 Mammals the large and widespread group of Apes and Half-Apes (Lemurs), which 

 in all modern systems constitute the independent order Primates, so named by Linne 

 because viewed as a whole they are the chief or most highly specialised members of 

 the class." We quoted the first sentence as an example of careless writing. We 

 have nothing more to add. — The Reviewer.]
