Dear Mr. Hatcher:

The address of Dr. R. H. Pfeiffer is 57 Francis Ave., Cambridge, Mass.,
of Prof. H. M Kallen (humanist and historian) - 411 West 114th Street, N.Y.C.

In my Mns. on the p. 88 (first chapter) there is a reference to a work on natural catastrophes. The ‘Ages in Chaos’ investigate the catastrophe for its chronological value (“when?”). The investigation in the nature of the upheavals of the past is the theme of another work important for the natural history. This other Mns (“Worlds in Collision”) will be ready sometimes next winter, when the historical work, with God’s help, may leave the press.

With kind regards
yours faithfully
