26 The Rev. N. S. Heineken on the Mechanical Productions 



* Sharp ') for turning, rose-work, eccentric, swash-work, geo- 

 metrical solids, &c., was sohl some few years since at Bradford 

 to Godfrey Wright, Esq., in the neighbourhood of Doncaster. 

 It had for many years been used by its former possessor 

 ( W. Goodchild), and when I saw it was in excellent working 

 condition ; and many are tlie elaborate and beautiful speci- 

 mens which I have seen of its efficiency, even at a period of 

 upwards of a century since it was first constructed. Another 

 smaller lathe, of a somewhat similar description, for turning 

 ovals, and ovals combined with rose-work, wliich exhibits some 

 ingenious contrivances of the same " master mind," was pur- 

 chased by a person whose name is " Murgy," residing at Hea- 

 ton near Bradford. The double sector mentioned in his bio- 

 graphy and sculptured on his monument, is, I understand, in 

 the possession of J. Bottomley, Esq. of Bradford, or his re- 

 lative Miss Bamforth, of Manor Row, Bradford. The large 

 (18-inch) elaborate ring dial, and also the set of calculating- 

 rods in a walking-stick, were purchased by Mr. Muff, music- 

 seller, Leeds. A beautifully divided plate for calculating, I was 

 informed, was in the possession of — Skelton, Esq. of Brad- 

 ford. A larce equatorial (with the hour circle about thirty 

 inches diameter) in complete preservation, was purchased at 

 the sale at Bradford, and is now at the observatory of the 

 York Philosophical Institution. A very ingenious and com- 

 plete perambulator, measuring from part of an inch to 100 

 miles, together with some geometrical solids, turned in the 

 first-mentioned lathe, now belong to my friend J. Water- 

 house, Esq., of Well Head near Halifax. Of this peram- 

 bulator I may observe, that it has only one toothed wheel in 

 the whole oi the machinery: all the intermediate measures 

 are given from the inch to the last index, which moves once in 

 100 miles; and yet the disc of the dial is not more than about 

 six inches in diameter and not a quarter of an inch in thick- 

 ness. Of this perambulator I have made a model, which (with 

 the consent of my friend) I will submit to you should you 

 desire it. A mural quadrant of 5^- feet radius, diagonally di- 

 vided, &c., I have in my own possession, and shall feel plea- 

 sure in showing it to any who may feel an interest about it. 

 A spirit thermometer, the scale of which I am certain was the 

 work of Abraham Sharp, from the punches nsed for the 

 figures, was fixed in the wainscot of the hall at Horton (his 

 residence). If the tube is the original one, this might be va- 

 luable for reference in a meteorological point of view ; for I 

 remember having seen many meteorological journals, which 

 had been kept by Abraham Sharp, and which were among 

 the papers left at Horton : these I believe are now in the
