Tarsias and the other Lemurida3 — between the elephant 

 and in a more striking manner between the Ornithorhyn- 

 chus or Echidna, and other mammals. But all these 

 breaks depend merely on the number of related forms 

 which have become extinct. At some future period, not 

 very distant as measured by centuries, the civilized races 

 of man will almost certainly exterminate and replace 

 throughout the world the savage races. At the same 

 time the anthropomorphous apes, as Prof. Schaaffhausen 

 has remarked, 16 will no doubt be exterminated. The 

 break will then be rendered wider, for it will intervene 

 between man in a more civilized state, as we may hope, 

 than the Caucasian, and some ape as low as a baboon, in- 

 stead of as at present between the negro or Australian 

 and the gorilla. 



With respect to the absence of fossil remains, serving 

 to connect man with his ape-like progenitors, no one will 

 lay much stress on this fact, who will read Sir C. Lyell's 

 discussion, 17 in which he shows that in all the vertebrate 

 classes the discovery of fossil remains has been an ex- 

 tremely slow and fortuitous process. Nor should it be 

 forgotten that those regions which are the most likely to 

 afford remains connecting man with some extinct ape-like 

 creature, have not as yet been searched by geologists. 



Lower Stages in the Genealogy of Man. — "We have 

 seen that man appears to have diverged from the Cata- 

 rhine or Old World division of the SimiadeB, after these 

 • had diverged from the ]STew World division. We will 

 now endeavor to follow the more remote traces of his 

 genealogy, trusting in the first place to the mutual affini- 

 ties between the various classes and orders, with some
