It will bo soon that tin' result of the investigation of the substance, 

 which has Ijeen oorchu'ttil here, rontlor it probable that there may be a 

 reniuuerative eomuiercial demand for this corundum, and I propose, 

 with your approval, to proceed further with the matter on the lines 

 suggested in the report. 



I would suggest that this report should be shown to Mr. Scrivenor, 

 with a view to his assistance in the further development of the subject 

 being secured since it is possible that deposits of this mineral occur 

 elsewhere in the Federate<l Malay States. 



I would also ask that the information contained in the report be 

 conveyed to Mr. Leonard Wray and the other gentleman who sub- 

 mitted specimens. 



I have, etc.,

A SPECIMEN of grey-blue corundum, weighing about •] ounces, was 

 forwarded to the Imperial Institute by Mr. Leonard Wray, the 

 Curator of tlie Perak Government Museum, and in the accom- 

 panying letter, dated the 28th November, 1903, he stated that he had 

 collected it near Ipoli in the Kinta District, where the mineral occurs 

 in more or less waterworn lumps in the drift which is woi'ked for tin. 

 At present no use is made of the conmduin, but it was thought that, 

 if it proved to be of marketable value, considerable quantities 

 could be procured. Mr. Cecil Wray, the Resident Magistrate of 

 Kinta, ha<l also collected a large quantity of the mineral at 

 Koban Sungei Kaiadi. 



On Mr. Leonard Wray's return to Perak he forwarded to the 

 Tmjjerial In.stitute a larger sample, weighing nearly 5 lbs., which 

 he had collected at Pulai, Sungei Raia, also in the Kinta District. In 

 the letter accompanying the consignment, No. 13/04, dated the 24th 

 February, 1904, he stated that the mineral occurs in quantity at or 

 near Pulai, and thought thei*e would be no difficulty in getting from 

 10 to 20 tons per month, judging from the amount he saw in the 

 mines. 



These two samples, the colour of which varies from pale V)lue to 

 bluish-grey, are exactly similar in characters. No well-develo]>ed 

 crystals are visible to the naked eye, the mineral occurs in compact, 

 finely granular masses made up of microscopic crystals. Most of the 

 pieces are more or less roimded by water action, though .the exact 

 manner in which this was brought about is not apparent.
