of the Oder; and entering Galicia, followed the base of the Carpathian mountains until he reached a small retired village at their foot, near Jaczinow, equidistant from the frontiers of Hungary and Moldavia. This quiet and sequestered spot afforded, in every respect, such a retreat as he sought; and he took up his abode in the house of a respectable farmer. Finding his situation very comfortable in this family, he made arrangements with the farmer and his wife, for his permanent residence with them; for, though his baldness and bareness never failed at first sight to operate repulsively, yet his countenance, deportment, and conversation speedily exercised so powerful an attraction, that no one ever parted from him without experiencing a very sincere regret.

After a lapse of four or five days, which were devoted to rest, and as many more to the ordering and cleaning of his apparatus, he began to put himself under

the permanent discipline of his compress and vacuum. He had brought with him a portable air-pump of his own invention, of strong power and most curious construction, adapted to act upon the rhombic form of each ratio, or, more properly speaking, of their nidi. His own compress consisted of a piece of solid gold, shaped to the ratio, and weighing three ounces : it was confined in a band which surrounded the cranion; and when fixed in its place, was secured by a tourniquet, which received a slight turn every morning, at first rising: at which period, the doctor found the texture of the cranion to be more compliant than at any other hour of the day. This compress had been made under his own direction, by an ingenious artist of Kustrin, from two watch-cases and a pair of shoe-buckles, long hereditary in the family; and he thought, that he could not pay a higher tribute of respect to his ancestors who wore them, than by exalting them to the

elevated office to which he had now destined them. The vacuum consisted of a vessel of the finest flint glass, with a rhombic orifice, three inches high, each inch divided into 30°, and graduated upwards on the outside, zero being exactly on a level with the actual surface of the nidus. The air-pump was exercised every morning, at the compliant season above mentioned, upon each nidus, until the effect became somewhat distressing, in order gradually to supple the obduracy of the cranion; after which, the compress and the vacuum were carefully affixed to their respective organs. To lengthen the adhesive effect of the vacuum, and to prevent its too frequent renewal, its rim was fixed to a piece of thick leather well soaked to resist the intrusion of the external air; and an assortment of these standing in a pan of water, together with a lamp, were always ready at hand to replace each as they became detached. Thus helmeted, our encephalologist passed

his days; absorbed into his own feelings, lest any cephalic symptom or sensation should escape his notice, and fail of due recordation.

He had also commenced his operations upon Gans; in order to which, the head of the latter had been very closely shaved. The preventive compress which he had contrived for it, consisted of calculated proportions of lead and zinc. Being unable himself to undertake the violence of the manual pneumatic exercise, lest he should displace or disturb his own attachments, he could only fix the instruments; and a servant of the farmer was employed as the active operator. As the effect of the operation was always very speedily sensible to his own head, he was extremely tender of the feelings of his co-patient, and cautioned the operator not to proceed with inconsiderate violence. After some minutes of pneumatic exhaustion, he asked Gans" How he did?" To which Gans replied, "That he was very well." The

doctor then directed the operator to increase the force of the action, until Gans should bid him desist, or should evince by his countenance some emotion of distress. When the operation had been gently continued for nearly a quarter of an hour, the doctor, who began to be alarmed, asked Gans "what he felt?" Gans, to whose perception the action had been only a soothing undulatory motion exciting somnolency, and who was fallen into a doze, made no reply; but being roused, and the question repeated, he said," that he "felt nothing." This insensibility a good deal perplexed the doctor; he imagined, that it must result from the perfection, and consequently the strength, of the arch of the concame-ratio. He therefore directed the operator to cease for the present. The same attempt was repeatedly made to rouse the sensibility of the cranion of Gans, but always with the same ill success; which became a source of very unseasonable disquietude to the doctor,
