The geographic and climatological data in Part II are given here as printed in the source document. In general they do not appear to be very reliable (see also the first paragraphs of Part II, Section II and the author’s remarks with some of the individual tables). There are inconsistencies in the data, and the conversion from degrees Fahrenheit to Celsius (or vice versa) and from inches to millimetres (or vice versa) has apparently not always been done with the same conversion factors or accuracy. Only obvious typographical errors in the data (where the location of the error could be identified) have been changed; see below under Changes. Similarly, the results of calculations (such as sums and means) do not always agree with the data on which they are supposed to be based; here, too, corrections have only been made in case of obvious typographical errors where the location of the error could be identified. A good deal of caution in using the data is advisable. Figures 3 and 12 are (apart from the caption) identical in the source document. Page I-57 and index: Cgaleka is possibly a typographical error for Chaleka or Chalekah Part II, Errata: the errata have already been corrected in the text. Page II-74 and index, C. Boliano: probably Cape Bolinao; Baryermassing possibly Banyermassing (Banjarmasin, although that is on Borneo rather than on Sumatra). Page II-91, table Molendo, monthly rainfall for June should probable read 0·06 Ins. Page II-100 and 101: data have not been corrected. Page II-103, entry Hann’s Klimatologie: there are no pages iii. or iv. in the second part. Changes made Some obvious minor typographical errors have been corrected silently.
