"Without entering, at this time, into minute anatomical and physiological explanation, it is sufficient to state that, _owing to relaxation of the ligaments of the knee-joint, by means of muscular action and pressure of the lower extremity against a point of resistance, the large bone of the leg_ (the tibia) is moved laterally upon the lower surface of the thigh bone (the femur), giving rise, in fact, to partial lateral dislocation." By comparing the portion italicized, in this note especially, it will be seen that the "doctors disagreed" very materially, making, in fact, two different statements. I had been so indignant at Dr. Foote's first intimation to me of what was coming, that if, when I slammed the door in his face, it had happened to come in contact with his nose, which he had so impertinently and hypocritically attempted to intrude into our rooms, I fear I should not have much regretted the accident; but anger evaporated over the perusal of this precious scientific performance; which was certainly enough to make me smile aloud over its absurdity. I saw at once that we could have nothing to fear from it, even though, at the first blush, its solemn professional air and tone might impose upon the ignorant and gratify the bigotry of some hostilities. I knew that the first sincere investigation, with special reference to this new and comical knee-joint theory, must at once explode it and cover its authors with confusion. I published the next day, in all the daily papers, the following card. It will be remembered that I was now alone in Buffalo with Maggie; mother and Katie being at New York. "TO DOCTORS FLINT, COVENTRY, and LEE: "GENTLEMEN--We observe, by a communication in _The Commercial Advertiser_, that you have recently made an examination of a 'highly respectable lady of this city,' by which you have discovered the secret of the 'Rochester impostors.' As we do not feel willing to rest under the imputation of being impostors, we are very willing to undergo a proper and decent examination, provided we can select three male and three female friends who shall be present on the occasion. "We can assure the public that there is no one more anxious than ourselves to discover the origin of these mysterious manifestations. If they can be explained on 'anatomical and physiological' principles, it is due to the world that the investigation be made, and that the 'humbug' be exposed. As there seems to be much interest manifested by the public on that subject, we would suggest that as early an investigation as is convenient would be acceptable to the undersigned. "A. LEAH FISH.
