We have been informed, that in Hudson’s-Bay, there has been very little alteration in the variation of the compass during the twenty years last past. XLII. _An Account of some extraordinary Tumors upon the Head of a labouring Man, now in_ St. Bartholomew’s _Hospital. By_ James Parsons, _M.D. F.R.S._ [Read Nov. 10, 1757.] THIS poor man, whose name is John Tomlinson, gives this account of himself: That he was born at or near Rotherham in Yorkshire, and is now about 25 years of age: that when he was a boy of four or five years old, at play with other children, he received a blow from one of them upon the top of his head; and believes that hurt, he then received, was the beginning of the appearances, that are represented before you. _See_ TAB. XIV. The tumor upon the top of his head, however, grew first, and, after having spread all over the vertex, extended gradually downwards over his right shoulder, and forwards over the _os frontis_, on the same side, till it stretched downwards into a lax flabby substance all over the right side of his face and shoulder: then the upper of the three anterior tumors arose from the large one; the middle one from the _ala nasi_, pulling it down by its weight, as you see it in Figure 1.[198]; and the lower one was pendulous from the inside of the great tumor by a narrow neck. These are the appearances which present themselves at first sight; but those under the great tumor are no less extraordinary; for, upon lifting up the great tumor, and looking up under it, his right eye comes in sight, with which he sees very well, and the eye is clear and sound; but the under lid is pulled down, and stretched to six or seven inches long, to which a tumor hung also, as large as that anterior one at the chin, the lowest of the three; besides several flaps and _rugæ_ of skin, and smaller tumors. [Illustration: _Philos. Trans. Vol. L._ TAB. XIV. _p. 350_. I. Parsons MD. _ad viv. del._ _J. Mynde sc._] The hairy scalp is so stretched by the vertical tumor, that the hairs are driven asunder; so that the tumor is in some places bald, and the whole is rugged and uneven. At its basis, all round, till we come to the extended part that goes away to the right shoulder, a bony edge may be distinctly felt, as if the skull was depressed at the top: and yet I cannot but believe, that there is no depression of the arch of the inner table, because the man was from his childhood ever very healthy; being never troubled with those symptoms, which usually attend a depression of the _cranium_. From this seeming edge the _os frontis_ shoots out a great way over the _ossa nasi_, perhaps to two or three inches beyond the frontal sinus’s; and is the basis, from which the great pendulous tumor hangs downwards and forwards.
