Hæmopthysis. This disease has been frequently feigned by sucking blood from the cheeks, gums, &c. but the professional inspector can never be deceived by such artifices; the appearance of the sputa, the state of pulse, &c. will always indicate the truth; besides which detection must be insured by a careful examination of the mouth and fauces.
Vomiting of Blood. Sauvages relates the case of a young woman who, to avoid the confinement of a convent, swallowed a quantity of bullock’s blood, and vomited it up in the presence of a physician sent to examine her. Where such a trick is suspected, we have only to secure the patient from the necessary supplies, and the fraud is at once detected.
Vomiting of Urine. Where this is asserted we may safely pronounce the patient an impostor, for the event is physiologically impossible.
Bloody Urine. An appearance of this nature is often produced in India by eating the Indian fig (Cactus Opuntia), or the fruit of the prickly pear, which imparts to the urine a blood-red colour. It has been also simulated by clandestinely pouring real blood, or colouring matter, into the night utensils. There is an old story of a boy who imposed on many by pretending to pass black urine; but being confined, he was detected in an attempt to secrete an ink-bottle, which pointed out the mode of his imposture.
Incontinence of Urine. The simulation of this affection may be detected by giving the patient a full dose of opium at night, without his knowledge, and introducing the catheter during sleep, or, by taking him by surprise during the day, and introducing the same instrument; when, if he be an impostor, it will be found that the urine has not drained off, guttatim, as it was secreted, but that the bladder possesses the power of retention. If the bed clothes are not found wet after a full dose of opium, during the operation of which the patient has been suddenly awoke, we may also be satisfied that there is no incontinence. Foderé says that if the penis is secured by a ligature, it will swell considerably in the real incontinence, in consequence of the urine running into the urethra; but that no such effect will happen if the disease be feigned.
Gravel and Stone. All impositions upon this subject may be detected by chemical analysis; in general, it will be sufficient to saw the pretended calculus into two parts, when the absence of the characteristic structure will establish the fraud; it will frequently be found that they are small pebbles, or coarse siliceous sand; Mr. Wilson[[571]] has related two instances of this kind in which an attempt was made to practise on his credulity; “many years ago,” says he, “when I resided in the house of Mr. Cruikshank, a person brought his son to that gentleman for surgical advice, asserting that the boy had long been cruelly afflicted with stone; in proof of which he produced several pieces of hard slaty substances, which he stated he had assisted the child in removing from the urethra; upon my expressing an opinion that these were not urinary concretions, he pretended to be angry, and indignantly left the house, declaring that he would seek for a surgeon to perform the operation for the removal of the stone, whose humanity would not let him doubt the assertion of a father, who, though in poverty, would gladly sacrifice his own existence to save that of his son: a few days after this he brought back the boy with a large piece of slate sticking in the urethra, which had torn the inner membrane, and from the swelling it had produced, was with much difficulty removed; wishing to detect the imposture, I persuaded him to leave the boy in Mr. Cruikshank’s house, under the pretence that the operation of lithotomy should be performed, if necessary; and it was only after the forms of binding the boy and bandaging his eyes were gone through, that he could be prevailed upon to confess his father had taught him to introduce these substances, which he had procured from coals, for the purpose of exciting commisseration for his pretended sufferings, and obtaining money from the charitably disposed; and perhaps, in this instance, to have extorted money from the surgeon to conceal his ignorance, had he seriously attempted to perform any operation.”
Alvine Concretions. It sometimes occurs that bodies of a very anomalous kind are passed from the intestines; but the medical practitioner by a careful examination of the substance, and a minute inquiry into the nature of all the ingesta, will frequently succeed in tracing their origin. Dr. Marcet, in his “Essay on Calculous Disorders,” relates some interesting instances of this kind, which we shall notice in this place, in order to put the medical man on his guard when called upon to deliver his opinion upon such occasions. The first case is that of some concretions put into Dr. Marcet’s hands by Sir Astley Cooper, and which had been discharged by a female patient, under circumstances which made it questionable whether they had proceeded from the rectum, or from the urethra; they were, however, discovered to be pieces of undigested cheese formed into balls by the action of the intestines, or portions of caseous matter actually formed in the intestines from milk taken as nourishment by the person, and coagulated by the gastric juices into those undigestible masses. Another singular species of intestinal calculus was found by Dr. Marcet and Dr. Wollaston to be oat-seeds, derived from the oaten cake which the patient had eaten. Dr. Marcet also describes a concretion which, by the assistance of Dr. Wollaston, he discovered to be those small woody knots which are often found in certain pears, and which the person had previously eaten. The last case which he relates is not less curious; a philosophical gentleman of delicate health, and disordered system, voided a number of small red globular bodies, each of which had in its centre two black opaque spots; they were supposed to be peculiar animals connected with his disorder, but Dr. Wollaston soon satisfied himself that they were nothing but the spawn of lobsters, an extremely indigestible substance, of which the patient acknowledged to have eaten about the time he passed these bodies. The author has deemed it necessary to introduce this subject under the present article; for, strange as it may appear, it not unfrequently happens, as Dr. Marcet has stated, that persons apparently respectable, produce bodies, as having been voided, which are wholly supposititious.
Abstinence from Food. Long fasting, or the power of refraining altogether from food for years, has been frequently the subject of imposition. The case of Anne Moore, of Tetbury, must be in the recollection of all our readers[[572]]; and in the Philosophical Transactions two cases are recorded, in one of which a man is said to have taken nothing but water for eighteen years, with now and then during a certain period of the year, a draught of clarified honey; but the case which has excited public interest in the greatest degree, is that of Elizabeth Canning, (for whose trial, see 10 Harg. St. Tri. 205, and 19 Howel St. Tri. 262) who, among other circumstances, pretended that she had been confined in a loft from Tuesday the 2d of January at four o’clock, A. M. until Monday the 29th, at four P. M. and that during this period she had had no sustenance, except about twenty-four pieces of bread to the amount of a quartern loaf, a penny mince-pye, and between three or four quarts of water; and yet that on the 28th day she made her escape by jumping out of the window, and walked twelve miles in six hours without taking food.[[573]] This story, incredible as it may appear, was actually believed by many persons, and popular clamour rose to a most indecent height; bills of indictment were preferred, and libels circulated without example either as to number or virulence; and Mary Squires, an unfortunate old gipsey, was condemned to death for the robbery charged to have been committed previous to this alleged, wanton imprisonment of the impostress Canning. One of the most interesting points in the evidence of these trials, (for there were several on different grounds,) was derived from the inspection of the linen of the impostress by an ingenious midwife, (19 How. St. Tri. 428) who observed that in twenty-eight days a menstrual period would probably have occurred, and yet there was no vestige of such an event to be traced on the linen; thus may physiological circumstances often elucidate points apparently remote from medical cognizance.
Deafness and Dumbness. Where the former of these maladies is alone simulated, the inspector will be able, with a little address, to detect the imposture; a sudden noise will frequently betray the patient, and an instance of this kind is related by Ambrose Paré; we may also contrive to communicate in his presence some circumstance in which he is greatly interested, and notice the effect of the intelligence upon his countenance, or upon his pulse. Where dumbness is only feigned, we should remember that the powers of articulation never leave a person without some cause, which medical inquiry must discover. It has been a question whether the absence of the tongue should be considered a sufficient reason for muteness; although we cannot dispute the validity of such a proof, it is necessary to know that cases are recorded[[574]] where persons did very well without that organ; but we are inclined to believe with Dr. Smith, that the muscles belonging to the tongue were, in such cases, not deficient. But these observations apply to instances of imposture, where deafness or dumbness have been singly simulated; suppose a medical practitioner is called upon to examine a patient who declares himself to labour under the misfortune of congenital deafness, and consequent dumbness, what plan of investigation is he to pursue upon such an occasion? It must be admitted that where this simulation is well performed, it becomes extremely difficult to detect it; but it requires so much art and perseverance that few persons will be found capable of the deception: M. Sichard succeeded in the detection of a most accomplished impostor, by requiring him to answer a number of queries in writing; when, the Abbé soon found that he spelt several words in compliance with their sound, instead of according to their established orthography; by substituting for instance the c for the q, which at once enabled the Abbé to declare that it was impossible that he should have been deaf and dumb from his birth, because he wrote as we hear, and not, as in the case of the real deaf and dumb, as we see.
Blindness. In cases of alledged amaurosis, the practitioner has generally relied upon the contractility of the pupil, as a test of vision; but Richter asserts that nothing positive can be drawn from the mobility or immobility of the iris, as sometimes the one and sometimes the other occurs; if however the pupil does not contract, we must think that the practitioner is authorised in concluding as to the existence of the disease. By unexpectedly reflecting the rays of the sun, by means of a mirror, upon the eye of the patient, we shall generally be able to discover any deception that may have been practised. Where short-sightedness is pleaded as a disqualification, the truth may be easily ascertained by inspection. The French adopted a very simple and ingenious mode of distinguishing the feigned myopes who endeavoured to escape the conscription laws; they placed spectacles of various powers upon the persons to be examined, and suddenly bringing before their eyes a printed paper, the subject of which was wholly unknown to them, the facility with which the person read pointed out with tolerable accuracy the state of his vision. A myope, for instance, and none but a myope, could read fluently a paper, brought close to his eyes, with concave glasses, and vice versâ.
