The accompanying sketch will make the details clear. Its 

 working has been very satisfactory. It requires no longer to 

 return to zero than for the galvanometer needle to come to 

 rest, and is correspondingly rapid and dead beat in its action. 

 It is much more sensitive than a thermo-pile of the same ex- 

 posed area. 



. An instrument in actual use having an opening of 8 mm de- 

 flects its galvanometer 30 divisions of its scale when the hand 

 is held a foot from the opening. A lighted match at six feet 

 drives the needle around to its stop.

1. The Taney Co., Missouri, Meteorite. 

 During June 1887 a meteoric mass came into my possession 

 and through the kindness of Miss Hattie Payne, of Lamar, 

 Ark., I learned that it was taken about thirty years before from 

 a spot in latitude 36° 35' north and longitude 93° 12' west of 

 Greenwich, near Miney, Taney Co., Missouri, eleven miles S.E„ 

 of Forsyth and over sixty miles from Limestone Valley, Ark. 

 Miss Payne also stated that about thirty years ago a meteorite 

 passed over the boundary line between Arkansas and Mis- 

 souri and was supposed to have fallen near by. After con- 

 siderable search, it was believed to have been located on a farm 

 eleven miles S.E. of Forsyth, whence it was taken sixty 

 miles to a farm in Limestone Valley, Newton Co., Arkansas, on 

 the supposition that it was of value. As it was decided not to- 

 be of meteoric origin, however, it remained unnoticed for twenty- 

 eight years, except that a few gun sights were made from it 

 by some of the curious neighbors. A portion of it was sent 

 to the writer and he at once secured the balance of the mass. 

 For figures see Plate X. The mass measures 34 cm X35 cm X 29 cm 

 and at the smaller end is 12 cm high. Its weight is 197 lbs., 

 (89"796 kilos). It is similar to the Hainholz, Westphalia, iron -5 ** 

 is one of the Syssideres of Daubree and of the Logronite group^ 

 of Meunier. Two large crystals of olivine are present, one 

 measuring 10 X 8 cm and another 4 X 6 cm ; this part being so 

 much lighter in color than the rest of the mass and so much 

 more easily detached that the larger crystals has been almost 

 entirely picked out to a depth of 5 cm . At one corner of the 

 mass there is an inclosure of augite measuring 7 X 4 0m . This
