38 THE ORGANIZATION OF 



spheroidal ball (v/, 7/ 1 ). It will be noticed, then, that there is on 

 one side of the yolk a light spot (c). Taking this spot as a 

 guiding point, and keeping it uppermost, the yolk should be cut 

 into, a short distance, at the side, in such a direction as would 

 divide it into halves, were the knife pressed through so as to 

 strike the middle of the white spot. As the pressure of the 

 knife flattens and smooths over the cut surface so as to obscure 



ing, the term, we, was used as representative of our combined authorship, and the 

 term, 7, whenever Prof. Agassiz wished to hold himself alone responsible for 

 anything said. And to keep the distinction always clear, when I myself in turn 

 was the sole authority, my name was mentioned in connection with it, either in 

 a note (vol. m. p. 237 ; vol. iv. pp. 41, 44), or in the body of the text (vol. iv. 

 pp. 61, 209, 237). In fact, so large a proportion of some of the volumes was the 

 result purely of my own work that I ought to have been represented as the sole 

 authority where the term, we, was used ; but as long as I was led to believe that I 

 should share it with Prof. Agassiz, I was content to let it appear so. So clear, 

 indeed, is my own individuality impressed upon these portions which I claim, 

 both in the nature of the microscopic work and the style of the language, a 

 totally different idiosyncrasy from that of Prof. Agassiz's, that, even as much as 

 two years before I had published my " Claim " in the pamphlet above mentioned, 

 European naturalists referred to the investigations as mine. This could hardly 

 be otherwise, as every working naturalist knows how such work is done, espe- 

 cially with the microscope ; and he is fully aware, too, that it cannot be delegated 

 to another to be done for him. The original authority must be the one who sits 

 over the microscope day after day, and month after month ; and when he takes 

 his pen in hand to describe what he has seen, and what he thinks of it, the very 

 character of the language shows that he who writes has seen and elaborated and 

 thought of what is written ; and his fellow-naturalists will recognize him in spite 

 of all the efforts of any one who may be so unscrupulous as to attempt to assume 

 the credit through any carefully studied arrangement of the title-page, and the 

 appearing to give due credit in an ingenuous preface. Naturalists do not look to 

 the preface to ascertain who is the author, but to the body of the work itself; 

 and any such subterfuge is quickly detected by them. Credit given in a preface, 

 and nowhere else, can only affect and influence the popular reader, who knows 

 nothing of, and can judge nothing of the merits of the work. How, and by what 

 representations, T was led to allow this wrong to accumulate in the third and 

 fourth volumes, cannot be entered into here, nor, unfortunately for myself, the 

 facts connected with the matter so easily proved, since the greatly lamented 

 death of one who, could he speak now, might reveal altogether too much for the 

 comfort and effrontery of the one who has done ine this great wrong. " Con- 

 scientia insanafrons aeneus."
