Monday Jan. 16 1928. New Orleans On last Saturday afternoon I got the long expected book by Du Toit "A Geological Comparison of South America with Africa", 1927 and published by the Carnegie Institution of Washington. Read it during the evening, again Sunday evening and today finished it. His comparisons are whistly geological and mainly lithological, with very little attention to paleontology. He endeavors to strengthen by keeping separate the two continents by a sea from 400 to 800 kilometers across, and enures north the Falkland Islands or there E-W structures can be aligned across the south Atlantic from the Cape of Good Hope to the west of Argentina. His hypothesis or hypothesis is to make an explanation, and in the end it does not explain, as he has no faith in the geograpic distribution of practically forms that aid all paleontology and depends almost on geological phenomena. On this basis he is still clinging similarities in the two continents but as the age determinations in many cases are not proven, the whole argument is one obtain from actual realities.
