The following interesting narrative is an abridged copy of what appeared in the Liverpool Mercury, at the time when her astonishing powers excited a considerable degree of public attention. The article is signed by Mr. Egerton Smith, the proprietor of the above paper, and his relation is founded on personal observations.
“Some time in September, 1816, I accompanied Dr. Renwick, on a professional visit he paid to Miss M‘Avoy, at her residence in St. Paul’s-square, on the east side. She was then between sixteen and seventeen years of age, of a pleasing and ingenuous countenance, and apparently of an amiable and artless disposition. Her mother informed me, that in the preceding June, her daughter had been attacked with hydrocephalus, or water in the head, together with paralytic affection on one side, and a complication of other disorders, which I forbear to enumerate, because I am wholly ignorant of that part of the subject. According to her own statement, corroborated by that of her mother, the hydrocephalus preceded, and in their opinion produced, the blindness of gutta serena, under which she is supposed to labour, but which has been called in question, I understand, by some of the professional men who have visited her.
“Her mother, however, declared, that the light of the sun produced not the slightest sensible effect upon her eyes; and some of the professional gentlemen who happened to be present at one of my repeated visits, declared, that though some slight contraction of the pupil was perceptible upon the approach of a lighted candle to the eye, it was by no means such as uniformly occurs when the visual organs perform their regular functions.
“At my first interview, I learned from herself, what I had indeed previously been told by others, that she had recently acquired the faculty of distinguishing not only the colours of cloth and stained glass, but that she could actually decipher the forms of words in a printed book; and, indeed, could read, if the phrase may be permitted, with tolerable facility. To put these pretensions to the test, she permitted a shawl to be passed across the eyes in double folds, in such a way that all present were convinced they could not under similar circumstances discern day from night. In this state a book was placed before her, and opened indiscriminately; when, to our extreme surprise, she began to trace the words with her finger, and to repeat them correctly. She appeared to recognize a short monosyllable by the simple contact of one finger; but in ascertaining a long word, she placed the fore-finger of her left hand on the beginning, whilst with that of her right hand she proceeded from the other extremity of the word; and when the two fingers, by having traversed over all the letters, came in contact with each other, she invariably and precisely ascertained the word. By my watch I found that she read about thirty words in half a minute; and it very naturally occurred to us, that if, notwithstanding her supposed blindness, and the double bandage over her eyes, she could still see, she would have read much more rapidly, if her motive had been to excite our astonishment. And here it may not be amiss to state, that there does not appear to be any adequate motive for practising a delusion upon the public. Her situation in life is respectable; and her mother disavows any intention of ever exhibiting her daughter as a means of pecuniary remuneration. Fifteen months have now elapsed since the period at which she laid claim to the extraordinary faculty which has given rise to so much curiosity, astonishment, and perplexity; during which time the reputation of so wonderful a circumstance has subjected her to the fatigue and inconvenience of daily and almost hourly visits.
“According to her own statement, her powers of touch vary very materially with circumstances; when her hands are cold, she declares that the faculty is altogether lost; and that it is exhausted, also, by long and unremitting efforts; that she considers the hours of from ten till twelve, of each alternate day, the most favourable for her performance. Her pulse, during the experiments, has varied from 110 to 130 degrees.
“One circumstance, which has created much doubt and suspicion, must not be concealed; which is, that if any substance, for instance, a book or a shawl, be interposed between her eyes and the object she is investigating, she is much embarrassed, and frequently entirely baffled. She explains this by saying, that it is necessary there should be an uninterrupted communication between her finger and her breath. I leave it to others to draw their own conclusions upon this point; as my object is not to establish any theory, or give currency to any mystery, but to relate the simple facts. I am, therefore, compelled to express my conviction, that she can neither ascertain colours, nor the words of a book, in total darkness; and, as many persons very naturally will ask, why has not such a test been proposed? the reply must be, that as the young lady is not the subject of a public exhibition, and as an introduction to her is merely a matter of favour, it might not be very courteous or delicate, under such circumstances, to make any proposal which seemed to imply a suspicion that she was an impostor.
“There are persons, however, who, giving her implicit credit for the reality of the extraordinary powers to which she lays claim, will contend that it is altogether unfair to propose the test of total darkness. Proceeding upon their belief that she actually ascertains colour, &c. by the finger, or that the visual organ is transferred to the touch, still they say that light is essentially necessary to produce that effect upon the surface of the body felt, which enables her to distinguish one shade from another; they add, that as there is no such thing as colour in total darkness, it is perfectly ridiculous to expect that she should ascertain the various shades without the presence of that light which alone produces those shades. It is, according to their mode of considering the subject, as absurd as to expect an effect without a cause.
“It has already been stated, that, with the double bandage over her eyes, she read several lines of a book indiscriminately opened; as it was possible that the letters of a printed book might leave some slight impression sensible to an exquisite touch, I took from my pocket-book an engraved French assignat, which was hot-pressed, and smooth as glass; she read the smallest lines contained in this with the same facility as the printed book. A letter received by that day’s post was produced, the direction and post-mark of which she immediately and correctly deciphered. She also named the colour of the separate parts of the dresses of the persons in company, as well as various shades of stained glass which were purposely brought.
“What I had seen at my first interview was so extremely astonishing, and so far surpassed any thing I had ever known or read of the powers ascribed to persons deprived of sight, that I could only account for it on the supposition that she was not blind, and that she had some secret mode of discerning an object, notwithstanding the bandage, through which I myself could not distinguish night from day, when it was applied to my own eyes. I therefore made the best apology I could for visiting her house again the same evening, having previously prepared myself with several tests, which I begged permission to submit to her examination, when the candle was withdrawn. Not the slightest objection was offered to my proposal, and the candle was extinguished: her mother stationed herself before the fire, which was extremely low, and afforded so little light that I could not have read one word of moderate-sized print, if it had been brought almost in contact with the bars of the grate. I then took from my pocket a small book, the type of which was very little larger than that of an ordinary newspaper; observing at the time, that I was afraid the print was too minute; to which she replied, that her fingers were in excellent order, and that she had no doubt she could be able to make it out.
“The candle, as was before observed, had been extinguished; and her mother and myself were so stationed, that had there been any light afforded by the fire, we must have completely intercepted it. Miss M‘Avoy sat in the furthest part of the room, with her back towards the grate, in such a situation that I could barely discern even the leaves of the book which lay open before her; the title of which she proceeded to read with complete success, with the exception of one very minute word. I then presented to her a small piece of smooth writing paper, which was ruled with horizontal faint blue lines, with a pen and black ink; there were also perpendicular red lines, between which were scored black lines: all these, with their direction and order, she determined without any apparent difficulty. She also told correctly the colour of a variety of species of cloth, procured immediately before at a draper’s shop. All the experiments hitherto described, as well as those which follow, were performed by Miss M. with the bandage before her eyes; and as the shawl, which was usually applied to this purpose, produced considerable warmth and inconvenience, a pair of what, in the optician’s shops, are called goggles, had been provided, which so completely excluded the light, that no person who tried them could discern the difference between day and night, when they were fitted to the face. As these goggles have been generally used when Miss M. has exhibited her surprising talent, it is necessary that the reader should have a correct idea of them. They are intended to be worn by travellers, to guard the eyes against the wind or the dust, and consist of two glasses, sometimes green, fitted into a bandage of leather, which is passed horizontally across the face, and is tied with ribands round the back of the head. The goggles provided for Miss M. instead of glasses, were fitted up with opake pasteboard, lined with paper, and not an aperture was left through which a single ray of light could penetrate.
