oil-fields with a view to reporting on their economic value, and 

 was incidentally attracted by the Tertiary remains that occur at 

 this locality. The ferruginous conglomerate, which proved to be 

 very useful in determining the geological features of the oil-fields, 

 was stated to contain numerous remains of Hippotherium ante- 

 lopinum and Aceraiherium perimense, and was therefore held to 

 be either of Pliocene or Upper Miocene age. The learned Doctor 

 found these chipped flints on a shelf of ferruginous conglomerate 

 on the eastern slope of a ravine high above its bottom, but below 

 the edge, in such a way that he could not conceive how they 

 could have been brought there by any foreign agency, and he 

 says that, to the best of his knowledge, he really found them 

 in situ. 



While Dr. Noetling was still occupied at Yenangyoung, Mr. 

 Oldham paid a visit to that place, and they made a search together 

 for more flints in the place where the first had been found, but 

 without success; and in his paper on "The Alleged Miocene 

 Man in Burma" ('Natural Science,' vii. 1895, p. 201), Mr. Oldham 

 stated that the flints are not confined to the outcrop of the ferru- 

 ginous conglomerate, but are scattered over the surface of the 

 plateau above. He further considers the flints to be natural 

 products. 



In answer to this, Dr. Noetling published, in ' Natural Science,' 

 x. 1897, p. 233, a further article " On the Discovery of Chipped 

 Flint Flakes in the Pliocene of Burma," objecting that, when the 

 implements occur on the plateau, as near Minlin-toung, at the 

 southern extremity of the dome, they were strictly confined to 

 the outcrop of the ferruginous conglomerate; and in this article 

 he introduced the facetted femur of Hippopotamus i?ravadicus, 

 which he found in a small streak of the conglomerate not far from 

 the flints, and which, as he believes can only have been facetted 

 by human agency. This be puts forward in support of the 

 Pliocene or Miocene flint implements as further proof of the 

 existence of the human species in Burma in Tertiary times. 



Since the publication of these discoveries many writers have 

 referred to them, and in most instances have accepted them as 

 proof of the vast antiquity of man in Burma, and no doubt, 

 besides the few references given here, many more could be found 

 by anyone with access to a good library. In Mandalay, however,
