have been glaciers throughout the periods of formation of the 

 sedimentary rocks but as I would explain their occurrence 

 by geographical conditions and attribute more to the sea 

 transporting ice with ice-bound material than to land-ice, I do

 much greater cold where they are found but only the drifting 

 of ice laden with debris. — AVhat we have to avoid is the 

 bolstering up of a good theory by bap evidence and claiming 

 a bill of indemnity for all sorts of false reasoning if the theory 

 or general results should afterwards turn out to be true*"
