Presentation notes by Gene Keyes

1) This is Cahill's first publication and exposition of the Butterfly Map of the world, in 1909.

2) I Xeroxed it back in 1973 from The Scottish Geographical Magazine. (Library, Southern Illinois University, Carbondale.)

3) In those days, Xerox could not do a satisfactory solid black. Therefore, the map-illustration continents, vivid silhouettes in the original, are badly faded in this Xerox. (Except p.464 above; see note 6)

4) Likewise, the Xerox text quality could not produce an OCR for a searchable PDF.

5) But this important article warrants wider visibility on the Web, so I have made jpegs from the Xerox of each page: enlarged and quite readable. (Less than full-size in your image viewer might degrade print quality, but it's your choice.)

6) On page 464, which carries the first and classic view of a Butterfly Map (above), I have enhanced the illustration by inserting a better Xerox of the same map from a later source (1919). Note, however, that the map's grid and continents were on white paper, not the age-darkened background picked up by the scanner. (While the content of my enhanced figure is just the same as the original, it is a composite of the older and newer, restoring the "Orbis Terrarum" omitted from the 1919 print.)

7) (I have also included p. 464 in its "bad-black" form, if you care to switch back and forth between the restored view, and the faded one—but which has a whiter background.)

8) The other pages' illustrations still have the poor, washed-out black of primitive Xerox, and should not be held against Cahill.

9) My pencil notations on the article remain; sorry about that. If someone would post a searchable PDF from the original journal, so much the better. I'm now too far from such a library to make a newer copy.
