SiK,— I have the houour to acknowledge the receipt of your letter 

 of 31st October (H.C. 8875/04) and to inform you that I will collect 

 and send to the Inij^erial Institute the large sample of corundum asked 

 for by Professor W. Duustan. 



I have, etc., 



The Federal Secretary, L. WRAY.

My dear Dunstan, — I send you by this post, in two boxes, a 

 sample, weighing 18 lbs., of what apjjears to me to be the best (quality 

 of corundum for the movements of clocks and watches. I shall be 

 much obliged, if, after trial, a sample of the stone, which proves to be 

 suited to the purpose, could be returned to me. Also a few cut 

 " jeAvels." 



I am also sending, in three boxes, the large sample you ask for. It 

 weighs about 5 cwt. 



I went to Pulai, in ITinta, on the 1 7th February, and collected the 

 whole sample from refuse heaps on one mine, in quite a short time. I 

 am sure it could be obtained in considerable quantities if there was a 

 demand for it, at a price which would cover cost of collection, bagging 

 and freight to England. 



I found a few pieces, with small well-formed hexagonal crystals on 

 them, of the same form as that of the sapphire. I also found one 

 large lump, with a portion of the matrix adhering to it. This appears 

 to be a mica-schist. 



I am, etc., 



Professor W. Dunstan, f.r.s., L. WRAY, 



Director. Imperial Institute.
