‘DR. GRUMMIDGE stated to the section a most interesting case of monomania, and described the course of treatment he had pursued with perfect success. The patient was a married lady in the middle rank of life, who, having seen another lady at an evening party in a full suit of pearls, was suddenly seized with a desire to possess a similar equipment, although her husband’s finances were by no means equal to the necessary outlay. Finding her wish ungratified, she fell sick, and the symptoms soon became so alarming, that he (Dr. Grummidge) was called in. At this period the prominent tokens of the disorder were sullenness, a total indisposition to perform domestic duties, great peevishness, and extreme languor, except when pearls were mentioned, at which times the pulse quickened, the eyes grew brighter, the pupils dilated, and the patient, after various incoherent exclamations, burst into a passion of tears, and exclaimed that nobody cared for her, and that she wished herself dead. Finding that the patient’s appetite was affected in the presence of company, he began by ordering a total abstinence from all stimulants, and forbidding any sustenance but weak gruel; he then took twenty ounces of blood, applied a blister under each ear, one upon the chest, and another on the back; having done which, and administered five grains of calomel, he left the patient to her repose. The next day she was somewhat low, but decidedly better, and all appearances of irritation were removed. The next day she improved still further, and on the next again. On the fourth there was some appearance of a return of the old symptoms, which no sooner developed themselves, than he administered another dose of calomel, and left strict orders that, unless a decidedly favourable change occurred within two hours, the patient’s head should be immediately shaved to the very last curl. From that moment she began to mend, and, in less than four-and-twenty hours was perfectly restored. She did not now betray the least emotion at the sight or mention of pearls or any other ornaments. She was cheerful and good-humoured, and a most beneficial change had been effected in her whole temperament and condition.
