"I think it was nearly three weeks ago that it was given out in a very authoritative tone, and, if I am not very much mistaken, the newly returned Minister from Bogota was the oracular organ used on the occasion to proclaim to the 'humbugged' citizens of Buffalo, that in twenty-four hours we should hear no more of the knockings. The news flew about the city with the rapidity of lightning, that the end of the 'rappings' was nigh, that an awful explosion was about to take place. A lady had been found who produced noises with the knee-joints. The University of Buffalo had examined the lady's knee-joints, heard the noises, and pronounced them identical with the sounds produced by the Rochester ladies, and, what was still more awful and astounding, the University of Buffalo were about to print their report in the Buffalo _Commercial Advertiser_. Who could withstand such a shock?--It was conceded on all hands that if the ladies could endure the University and the _Commercial Advertiser_, they need never fear any natural catastrophe. True to the prediction, out came the 'report.' Three wise men had spoken, yea, three _professors_, professors even of Materia Medica, Physiology, and of Principles and Practice of Medicine. Be it remembered, too, that the University was under the guidance of that good man, Millard Fillmore, as Chancellor, and Dr. Thomas M. Foote, late Minister to Bogota, as one of its council men--thus uniting to the collective wisdom of the professors the great head of the nation, and speaking through his immediate organ, the _Commercial Advertiser_. Buffalo was the great battle-ground and the University the great adversary chosen to annihilate this already too wide-spread imposture. Now, do not understand me as attributing any unkind motive to those gentlemen professors; I have no doubt they were actuated by a nice sense of duty which they owed to science and to their fellow-beings to make the exposé. I could not say a word against Dr. Lee or Dr. Coventry, if I wanted to; they are strangers to most of our citizens, and only come among us periodically, and I am informed that they are very much respected so far as they have extended their acquaintance here. Professor Flint has been a resident of this city for many years, and is regarded by those that employ him as an able practitioner of medicine. He conducts the editorial management of the Buffalo _Medical Journal_, in the last number of which he has devoted a large portion of its columns to the matter of these 'mysterious manifestations.' I am only sorry that its circulation is so limited as not to allow the investigating public to appreciate its strictures. He intimates that the 'report' was hastily drawn up and contains errors, and in order to do the professors justice, requests the press to recopy the article as amended. There is certainly no impropriety in all that, if the University left out some material argument, in their hurry to explode a humbug of such vast magnitude.
