A number of physicians who had given testimonials were asked in writing whether the testimonials were genuine and whether they still entertained the high opinion of Neurilla expressed at a former date. Several replied that, if they had ever given such testimonials, they had forgotten the circumstance. From the replies received we select the following: The testimonial which bears Dr. A’s name reads: “_I am using Neurilla with most satisfactory results._” Dr. A now says: “=As to its positive value as a therapeutic agent I have not used it enough to know.... If the language you quote ... appears as given in or as a ‘testimonial’ it must in some way be garbled and appears wholly without my knowledge or consent.=” Dr. B is quoted as having written: “_I do not often lend my influence to furthering the fame of a proprietary remedy, but I have achieved such excellent results from the use of Neurilla as a calmative in hysteria and other nervous disorders, that I feel its manufacturers are entitled to an acknowledgment of gratitude from me._” Dr. B writes: “=I have not prescribed a dose of the nostrum in years. The use of my name in connection with Neurilla is unauthorized.=” Dr. C once wrote: “_I have used Neurilla with good results._” Dr. C now writes: =“In re ‘Neurilla’ I think I used the preparation once or twice and it seemed to do good work, but if due to the preparation or other influences, I am not able to verify. I have not used it since nor will, as I am opposed to using these preparations except in certain cases where the ℞ contains remedies whose value I have verified under the most rigid tests.= “=P. S. This testimonial must have been given many years ago.=” Dr. D’s testimonial is admitted to be based on a single case: “_I am using Neurilla in a bad case of neuralgic tic with very good results on an aged lady. She has taken several bottles, and is still taking it with very good results._” Dr. D sums up his later experience by saying: “=I have long since abandoned the use of Neurilla in practice.=” The following bears Dr. E’s name: “_I endorse Neurilla without hesitation. It meets all indications for which it is intended._” This is what Dr. E writes now: “=As to the enclosed testimonial in regard to Neurilla said to be written by me I have no recollection. I am not prescribing Neurilla.=” Dr. F’s experience is similar. The testimonial credited to him reads: “_I have prescribed Neurilla in nervous disorders with good results._” Dr. F now writes: “=I don’t remember of ever having prescribed ‘Neurilla’ or of having given a testimonial for it or any other patent medicine if I knew it to be so.=” SUMMARY
