In the analysis of Mr. Piddington of the same meteorite, the mag- 

 nesia had escaped him and remained with the iron, which has been 

 now prevented owing to the later improvements in Chemical Analysis. 

 Yon Hauer found the oxygen of the bases to the oxygen of the acids 

 in the ratio of 1 : 2,42 or between bisilicates and trisilicates. Dr. Haid- 

 inger says : " Stromeyer airead}?- had found a somewhat analagous ratio 

 in an olivine-like body inclosed in a meteoric iron from Saxony. Pro- 

 fessor Shepard had given the ñame of Chladoite to a real trisilicate 

 contained in the Bishopsville meteorites. This certainly new species in 

 the Shalka meteorite, I thought it my duty to ñame Piddingtonite, 

 in commemoration of that really indefatigable labourer in Natural 

 Sciences to whom we owe the rescue of that most remarkable meteo- 

 rite of Shalka, and in commemoration too, of the kindness with which 

 you acceded to our proposals of exchange." 



Dr. Haidinger adds that he was engaged in the further investiga- 

 tion of the specimens sent and he hoped to forward a series to the 

 Society from their collections. 



When the proceedings of the Academy of Vienna for June arrive, 

 I would suggest that a translation of the valuable account given by 

 Dr. Haidinger of this meteorite should be published in the Journal. 

 I have only given a few of the heads of the notice. 



Dr. Haidinger sends two copies of their more recent catalogues 

 of meteorites, and begs me to hand you one for Asiatic Society. 



I inclose it, you will see that all the Society sent have been embodi- 

 ed in this. The large mass of iron from the Kurruckpur Hills was 

 considered as by ourselves doubtfully meteoric, but we shall soon have 

 the result of the careful analysis.
