DR. W. FLIGHT ON THE METEORITES OF 
magnetic needle and found not to be in the slightest degree magnetic. It was shown 
on analysis to have the composition: 
The protosulphide requires 
Sulphur. = 36*073 36*36 
Iron. =[63*927] 63*64 
100*000 100*00 
Some fragments of the iron were sawn into very thin plates, and were kept quite 
cool all the time by a current of methylated spirit; they were carefully dried and 
weighed, and the gas drawn from them when at a bright red-heat with a Sprengel 
pump. The plates of iron taken measured 1*198 cub. centim., and the gas collected 
after many hours’ heating was 6*38 times the bulk of the metal. This is about double 
the quantity met with by Graham and Mallet in other meteoric irons which had 
lain a long time in the ground. 
XIII. The gases occluded by the Rowton nickel-iron . 
After subtracting a little oxygen and the corresponding amount of nitrogen, due 
probably to the entrance of a little air into the apparatus, the gas was found to have 
the following percentage composition :— 
Carbonic acid. 5*155 
Hydrogen. 77*778 
Carbonic oxide. 7*345 
Nitrogen. 9*722 
100*000 
Plate 53 shows a drawing of the mass (fig. 4, actual size) as well as a sketch of the 
figures developed by etching the surface with bromine (fig. 5); they show larger figures 
than are usual, with less of the bright extruded ingredient, doubtless a compound 
rich in phosphorus. The small darker-coloured rounded mass near the bottom of the 
section is a nodule of troilite. 
XIV. The Meteorite of Middlesbrough, Yorkshire. 
During the past year a very beautiful specimen of a meteorite fell near Middles¬ 
brough, in Yorkshire. It struck the earth at a spot called Pennyman’s Siding, on 
the North-Eastern Railway Company’s branch line from Middlesbrough to Guis- 
brough, about one mile and three-quarters from the former town. Its descent was 
witnessed by VY. Ellinor and three platelayers, who heard a whizzing or rushing noise
