 April l6(35, at Kettering in Yorkshire, where Henry Jenkins of Ellerton upon 

 Swale, labourer, aged 1 57 years, was produced, and he deposed as a witness.

On making Pitch, Tar, and Oil, out of a blackish Stone in Shropshire. By Mr. 

 Martin Ele, the Inventor of it. N° 228, p. 544. 



In Brosely, Bently, Pitchford, and other adjacent places in Shropshire, there 

 lies over most of the coal-pits or mines, a stratum or layer of a blackish rock, 

 or stone, of some thickness, which is porous, and contains in it great quantities 

 of bituminous matter. This stone being brought to the workhouse, is ground 

 small by horse-mills, such as are used for grinding flints to make glass of. The 

 powder is thrown into great coppers of water, where, by boiling, the bitumi- 

 nous matter is separated from the stony or gritty part ; this last sinking to the 

 bottom, the other swimming at the top of the water. This bituminous sub- 

 stance being gathered together, and evaporated, comes to the consistence of 

 pitch ; and this by means of an oil, distilled from the same stone, and mixed 

 with the pitch, becomes thinner, or like tar. These substances are found to 

 exceed common pitch and tar, as they do not crack, but always keep black and 

 soft, by which they may prevent the worm from getting into the ships pitched 

 with it. The oil may be used for oil of petre, or turpentine, and has been 

 tried in aches or pains. 



Account of a Book, viz. — Marcelli Malpig/iii Philosophi et Medici Bononiensis

This work of Malpighius was delivered when he found himself near the 

 period of his life, with orders to send it to the Royal Society after his death, 

 by whose care it was published, being the last remains of the illustrious Malpighi, 

 giving an account of his whole studies, and some remarkable passages of his 

 life.* 



The subjects contained in this vol. besides the author's memoirs of himself, 

 relate principally to physiology and comparative anatomy. At the end are re- 

 printed his observations on the structure of the glands, 



* Of this life an abstract has already been given at p. 171, vol. 1, of these Abridgments.
