714 Examination and Analysis of two species of Coal. [No. 7. 



specimens of this type, all of which agree in every letter of the 

 legend. There is therefore, no doubt about the reading of the 

 letters. 



I cannot close this account without saying a few words in favour 

 of my claim to the discovery of the true values of eleven letters, or 

 of just one-third of the Ariano-Pali alphabet. The whole number 

 of single-letters amount to thirty-five, of which Jas. Prinsep had 

 assigned the true value to seventeen, or just one-half. To Mr. 

 Norris is due the discovery of six single letters of which two are 

 the monumental forms of ch and its aspirate ; and the form of one 

 letter jh still remains unknown. Of the nine known vowels (five 

 initial and four medial) seven were determined by Jas. Prinsep, and 

 two by me. Of the few compound letters which are at present 

 known, the numismatic anuswara was discovered by Jas. Prinsep, 

 the monumental one by Mr. Norris : but the attached r in Jcra, tra, 

 dra and stra ; the attached t in st, the attached m in rm are all due 

 to myself. The single letters of which I claim the discovery are 

 g, gh, ng ; ch, chh ; t, d; ph, b, hh ; v ; all of which, with the excep- 

 tion of the fourth and fifth, were made known in this Journal before 

 the publication of Mr. Norris's alphabet in the Journal of the Eoyal 

 Asiatic Societv for 1846. 



Examination and Analysis of two specimens of Coal from Ava, by 

 H. Piddington, Curator Museum Economic Geology. 



I am indebted for these two specimens to Captain Niblett of the 

 H. C. Steamer Sesostris. Of No. 1, we have a capital supply of a 

 maund or more, but of No. 2, we have only a little in a box ; but 

 quite sufficient to shew that it is altogether a different coal even by 

 inspection : and with specimens of coal these remarks are not super- 

 fluous, for it is only by a good large supply of the coal that its 

 quality can be fairly judged of and fair samples taken for analysis. 



No. I. 

 Semi-Bituminous Coal. 



No locality has been given with these specimens but we have in 

 the collections of the Museum specimens in Major Burney's series
