Mr. A. Jensen,
New York City.

Dear Sir:

I am glad to have had the privilege of looking over the manuscript of your system of combined massage and exercise.

The results so far as I have observed them have been excellent. This combined treatment possesses manifest advantages over either massage or exercises given separately.

The fact that no apparatus is needed and that the strength of the individual adapts the course or treatment to his particular need, renders it generally applicable.

Very truly,

(Signed) E. L. Kellogg.
