THE GEOLOGIST. 
MAECH 1862. 
FOSSIL MONKEYS. 
By Cha-rles Carter Blake, Esq. 
In tliese days of progress, wlien the alleged origin of the human 
race from a transmuted gorilla is canvassed as a demonstrable and 
demonstrated theory by many geologists and zoologists, and the pens 
of various distinguished writers are occupied to prove the absolute 
identity of man's physiological and psychological nature with that of 
the beasts of the field, it behoves the candid student of palaeontology 
to inquire what are the fossil members of the Order of Mammalia 
immediately beneath man — the Quadrumana, and whether they are 
such individuals as might fulfil the hypothetical condition of being 
his ancestors, under any of the " derivative " theories propounded by 
Darwin or Lamarck. 
In venturing upon this field of error, doubt, and confusion, I wish 
dispassionately to endeavour to divest myself of any adherence to any 
Humerus of Lri/opitkecus Tontani. (Scale \ linear.) 
prevailing doctrine. Imbued strongly with the conviction of the unity 
of type of all animals, and with the probability of their common
