out the months and days, as it moves, on the fixed wheel CC. Round the edge of this wheel in a grove in the catgut string M  M, crossing in the bar at N, and, going also in a grove, round the pulley G, which is fixed on the axis F, turns the pulley with its axes, to which are fixed the black lead pencils e and m, perpendicular under the little balls E and M representing the Earth and Moon; carrying M round E in the same time as m round e. On this axis also is fixed an index, which in the same time goes round a small plate at B divided into 29 1/2 equal parts, which are for the days of the moon's age. S represents the sun, whose center is 86 inches distant from the center of E the earth, from which the center of M the moon is 24/100 parts of an inch distant, to keep the due proportion: for as 86 inches is to 86 millions of miles, the earth's distance from the sun, so is 24/100 parts of an inch to 240 thousand miles, the moon's distance from the earth. The diameter of the wheel CC is to the diameter of the pulley G as a year is to a lunation; consequently in the time that the long bar is once moved round the fixed wheel CC, the index D will go over all the days of the months on that wheel, and the little moon M will describe as many revolutions round its earth E as the celestial moon does round [[crossed out "the"]] our earth in a year. And if a long paper be properly stretched on the floor, under the pencils e and m which move as E and M do, the pencil e (as in Fig.  , which is exactly copied from one of the figures in my harvest moon pamphlet, published in 1747) will describe the regular curve or line of the earth's annual motion AB, while the pencil in going round e will describe the line of the moon's path CD, which is concave to the sun throughout even at new moon; cosign the earth's path at the first and third quarters, lying betwixt it and the sun at new moon, and beyond it [[crossed out "at the"]] from the sun at full moon, as represented in the figure, where NM signifies new moon, PQ the first quarter, FM full moon, and 3Q the third quarter.

In the Gents mag. for May 1742. p. 265 is a description of an instrument, which makes the figure of the moon's path, instead of being ^always^ concave to the sun, turnoff from it in a sharp angle at every new moon. The paths in different lunation's appearing like so many segments of lesser circles joined together at their ends, with their angular points all turned towards one common center where the sun is supposed to be placed. 

My scheme of the moon's path on large paper is sold by Mrs. Senex at the globe opposite St. Dunstan's church Fleet-street. Price 1.s6.d J. Ferguson.

[[side note]] On steel[ for magnets, promis on p. 125. [[/side note]]

All sorts of steel are not equally proper for making artificial magnets, the common English blister steel, and the rose steel are not amiss; that marked with an ace of clubs and an ace of hearts is better; but the best of all is a sort marked with a double spur and star. The rose and blister steels will do best heated red hot, and then suddenly quenched in a large quantity of cold water; this succeeds well in small bars; but if the magnets are to be half or three-quarters of an inch thick, it will be very difficult to impregnate them with the magnetic virtue when they are thus

first "s" in words with two "s"s looks like a cursive "f".
