in this memoir and called by Haeckel allceogenesis, has been ever 

 since a stumbling block to all theories of genetic relationship 

 among Medusae. 



Two short papers recently published, the one by Schulze (Nat. 

 Wiss. Ver. f. Steiermark, 1875, p. 125), and the other by Uljauin 

 (Archiv f. Naturg., 1875, p. 333), have, however, proved conclu- 

 sively that Hseckel's theory, like many other of his vagaries, had 

 no foundation of truth. It was based not merely on an incorrect 

 interpretation of facts, but the facts themselves existed only in his 

 imagination. 



As, perhaps, with the exception of his monograph of the Radi- 

 olaria, no other memoir has contributed more than the one above

 that this same genetic connection has furnished the text for many 

 a sermon from their high priest. Infallible himself, he has been 

 paring in his condemnation of the ignorance and shallowness 

 opponents. Proved now to be in the wrong, we expect

 and cannot fail to interest. The facts presented are some of the 

 strangest that have been brought to light by recent investigations, 

 and not the least marvelous are those relating to man's parasites.
