Pièce 48 - Letter from William Clark

1 p

Cambridge - WC returns the fourth sheet: 'I think section 3 excellent: and so in general the rest'. WC has two objections: 'It appears that the successive teeth of the Crocodile can scarcely be compared with the germs of new creatures included within germs - because each of the germs of the teeth which are, in succession, to take the place of any existing tooth, is included in a common membrane. So that the successive teeth would rather bear an analogy to members of the same family, than to consecutive generations'. Secondly, physiologists like Dr Marshall Hall will not like 'your distinction between the animal and organic powers'. WC looks forward to the way WW 'will establish the one controlling power, which must keep all the separate vital forces in order - as I presume you must according to your plan, as far as I see it'.
