What reading level is On Centenarians; And the Duration of the Human Race : a Fresh And Authentic Enquiry; With Historical Notes, Criticisms, And Speculations book?
To quickly assess the difficulty of the text, read a short excerpt:
Many theories of Immunity have been proposed which I need not describe : it is sufficient to remark that an original susceptibility to disease may be converted into a power of resistance against a subsequent infection by (i) the natural susceptibility to it being, ipso facto, removed by the mere fact of recovery. This is Nature's formula that restoration from an acquired infection is followed by an increased capacity of effective opposition to sequent attacks ; (ii) an artificial power of resis...tance may be communicated by inoculation with the attenuated virus ; that is to say, by inoculation with the living micro- organisms or their spores ; or (iii), in place of employing this method of inoculation, small doses of living and virulent organisms may be administered to produce artificial immunity.
* The Origin of Species : chap. iv.
It has been shown also that some of the elements of immunity constitute a portion of the physical apparatus ; and that the tissues possess a naturally competent defensive and protective capacity of development into more effective service.
