[If, then, there be some degree of truth in these remarks, we have no right to expect to find in our geological sections an infinite number of «those fine» transitional forms, which on our theory assuredly have ct2onnecting & «which» «must» have connected all species past & [text cut and lost] «long» [text cut and lost] branching «& diverges «& diverging»» chains «of life.» All that [text cut and lost]
