I am confident that you will be highly delighted with the splendid effects of the Tablets at the end of a few weeks if you follow carefully my instructions and are prompt and regular in taking the Tablets. I am sending you herewith printed instructions and rules for diet. You will note that our suggestion as to what you should eat, if strictly followed, will not work any hardship, and that you will never go hungry.... This letter, signed “________ ‘Adviser, Fell Formula Association,’” was accompanied by a printed circular giving rules as to diet, etc., and by a “symptom blank,” to be filled up by the patient in order to obtain particulars of “the Fell System of Simple Muscular Movements for Reducing the Weight and Increasing the Strength, in combination with the ‘Fell’ Reducing Treatment”; it appears from the latter that particulars of these exercises are only supplied when the 26s. case is sent for. A fourth letter dealt with generalities and recommended taking the reducing treatment in increased quantities, but after an interval a fifth was received, enclosing a booklet advocating the use of “the Century Thermal Bath Cabinet,” from which the following are extracts: ... We have strongly recommended the Home Turkish Bath that it may be used at least once a week as an adjunct to the Reducing Treatment; hence our affiliation to the “Century Thermal” Bath Cabinet, Ltd., whose home cabinet is built on such lines as to render it the best device extant for taking Hot Air or Vapour Baths. ... in any event, it were better to spend the required amount, for were the cost as much as £10 in all (it has but rarely exceeded that) the expense is out of all proportion to the ultimate benefit. ... with the Fell treatment no case of obesity, in either sex, can fail to be reduced if assisted with the regular use of the Hot Air Bath. Booklets entitled _Corpulence or Obesity. Its causes, results, and successful treatment: The Treatment of Obesity by the “Fell” Reducing Treatment_: and _Make Muscle of your Fat_, were also sent at different times. The following extracts from two of these scarcely appear consistent: A Guarantee to Reduce Weight. It is not our purpose to indulge in empty talk only, or in unconsequential boasts. We are prepared to, and do, give a positive guarantee that the Fell Treatment, used in conjunction with the Muscular System, will reduce the fat of any person—provided our instructions are adhered to—in the space of a very few weeks. Do We Guarantee? We are frequently asked this question personally and by letter, and reply emphatically—No, we do not. To say Yes—would be illogical and certainly demoralising.
