Excerpt from An Introduction to the Study of Variable Stars
Mr. Olcott, secretary of the American Variable Star Section, made suggestions as to what points the amateur observer would be especially interested in, and sent several items which have been incorporated in the chapter on Hints to Observ ers. Mr. David Blencoe, also a member of the Association, has kindly sent his work on a statistical study of variable stars, which had been prepared for private circulation.
The author's greatest debt, however, is to Miss Helen Van Kleeck, who at several times in the past has assisted in prepar ing the publications of Vassar College for the press. To her faithful and intelligent work in transcription the writer owes the completion of the volume in the required time, and to her careful criticism is due much of the clearness of style. Miss Van Kleeck also prepared the drawings for the illustrations, which are provided for by the publication fund of the Observa tory.
