1899] MORE NORTH AMERICAN COPEPODS 9 



that the Atlantic probably presents no barrier to its passage from 

 Europe to America, and vice, versa. 



The paper gives keys and descriptions of the very peculiar and 

 interesting forms coming within its scope, but unfortunately it is not 

 accompanied by any figures. It may be perfectly true, as stated, that 

 " the species treated may be identified by figures already published," 

 but this information is more tantalising than useful. 



The Biology of the Victorian Era. 



That the Liverpool Biological Society is as vigorous as ever is evident 

 from the twelfth volume of its Proceedings and Transactions, which is 

 full of interesting material. It begins with an inaugural address by 

 Mr. Isaac C. Thompson on "Advances in Biological Science during the 

 Victorian Era." This was a large order for one lecture, and Mr. Thomp- 

 son's courage cannot be doubted. The result is a very delightful 

 retrospect, though it lacks that completeness of outlook which we find, 

 for instance, in Huxley's masterly sketch of an even wider subject — 

 the Science of the Victorian Era. The bulk of Mr. Thompson's address 

 is devoted, as is just, to evolution doctrine, and Darwin's work fills up 

 so much of the picture that many great achievements have been 

 crowded out. We miss, for instance, any recognition of such dis- 

 tinctive advances as the study of the cell, the conception of germinal 

 continuity, the "protoplasmic movement" in physiology, the beginnings 

 of physiological embryology, and many more. We sometimes wonder if 

 there is not a hint of megalomania in much of our talk about " evolu- 

 tion," when even the foundations of the doctrine are still so far from 

 secure. But the picture given in this address is so pleasant and vivid 

 that it seems ungracious to complain that there are not more figures 

 in it. There are visible figures, too — an interesting innovation — for 

 the paper is illustrated by photographs of Charles Darwin, Erasmus 

 Darwin, Cuvier, Edward Eorbes, Wyville Thomson, Huxley, Pasteur, 

 Spencer, Haeckel, Wallace, Weismann, Lister, and Herdman. 



A Half-Century of Evolution. 



As the wonderful century draws near its end we shall be deluged with 

 retrospects, and truly these arbitrary time-boundaries may have their 

 use in stimulating a feeling for history. It is to be hoped, however, 

 that the note of jubilation which has already been loudly sounded by 

 some will be softened by criticism, and that more will follow Mr. 

 Wallace in recording the century's failures alongside of its successes. 

 In his address to the section of zoology on the occasion of the fiftieth 

 anniversary of the American Association for the Advancement of 

 Science (August 1898), Prof. Alpheus S. Packard seems to have 

 sought the via media, but we are not sure that he has always kept to
