644 페이지 - OWEN.— LECTURES ON THE COMPARATIVE ANATOMY AND PHYSIOLOGY of the VERTEBRATE ANIMALS, delivered at the Royal College of Surgeons in 1844 and 1846.
xxxiv 페이지 - ... has to maintain against the surrounding agencies that are ever tending to dissolve the vital bond and subjugate the living matter to the ordinary chemical and physical forces.
361 페이지 - ... for uprooting or cutting down trees, or for transport and working of building materials ; they are characteristic of age and sex ; and in man they have secondary relations subservient to beauty and to speech. Teeth are always...
