THE STORY OF NINETEENTH-CENTURY SCIENCE 



Prohibitorum could avail to hide from eager human 

 eyes such pages of the geologic story as Nature herself 

 had spared. Eager searchers were turning the leaves 

 with renewed zeal everywhere, and with no small meas- 

 ure of success. In particular, interest attached just at 

 this time to a human skull which Dr. Fuhlrott had dis- 



PROTOROHTPPUS, THE ANCESTRAL FOUR-TOED HORSE 

 Height at shoulder, 16 inches. From the Big Horn Mountains 



covered in a cave at Neanderthal two or three years be- 

 fore a cranium which has ever since been famous as 

 the Neanderthal skull, the type specimen of what mod- 

 ern zoologists are disposed to regard as a distinct spe- 

 cies of man, Homo neanderthalensis. Like others of the 

 same type since discovered at Spy, it is singularly Simian 

 in character low-arched, with receding forehead and 

 enormous protuberant eyebrows. When it was first ex- 

 hibited to the scientists at Berlin by Dr. Fuhlrott, in 

 1857, its human character was doubted by some of the 

 witnesses \ of that, however, there is no present question.
