None of my departments has shown a more gratifying development than has the correspondence department. Letters pour in from all parts of the world asking for advice and instruction in such numbers that I have been obliged to organise a special system and department for dealing with the enquiries of my many friends, who, owing to their living at a distance and to other reasons, cannot attend the schools personally. Every week many letters reach me from the Colonies alone--from India, Canada, Australia, South Africa--even from distant Klondike--and from one and all I have received flattering testimonials as to the benefits they have derived from following my instructions. This is an example:--Mr. Dunbar, of Queensland, writes:— “Dear Mr. Sandow, “I cannot express my gratitude for the wonderful benefit I have derived from your three months’ course of instruction. Previous to practising your system I was a chronic dyspeptic, and owing to my sedentary occupation, for many years I had not known what it was to feel the natural exhilaration and energy of a healthy man. Now I honestly believe that there is not a healthier man in the whole Colony.” One pleasing feature of this undertaking is the steady increase in the number of applications from ladies. This department has already become the most important part of my work, and anyone wishing to keep in touch with my system of Physical Culture can do so by forwarding to me their measurements, sex, age, and occupation. In the case of any physical peculiarity, or organic weakness, a doctor should be consulted, and the result of his examination stated in the letter of communication. A form is inserted at the end of this book as a guide to those wishing to apply. These forms are dealt with by myself and each case receives my individual consideration and instruction, and is signed by me. CHAPTER XII. SANDOW’S CHART OF MEASUREMENTS. The figure will show pupils how to take their own measurements. They are advised to keep a careful record of these month by month, so they can see how they are progressing. The chest should be measured both with the lungs full of air and empty, as well as in its normal condition. _Date when training commenced._ ..................................................... _Date on completion of course._ ..................................................... _Measurements then._ _Measurements now._ _Age_ _Weight_ _Height_ _Neck_ _Chest Contracted_ _Chest Expanded_ _Upper Right Arm_ _Upper Left Arm_ _Forearm, Right_ _Forearm, Left_ _Waist_ _Thigh, Right_ _Thigh, Left_ _Calf, Right_ _Calf, Left_ [Illustration: Showing the positions of measurement] CHAPTER XIII. THE COMBINED DEVELOPER. After considerable experience and exhaustive experiments with rubber machines, I have succeeded in inventing one which allows of a combination of dumb-bell and rubber exercises.
