tense heat, and it is no doubt to this capability of peifectiv inti- 

 mate mixture between tliese two bodies, and to their great capa- 

 city for heat, that the effects of the compound blowpipe are in a 

 great measure to be ascribed.'' 



Clark, Journal Royal Institution, page 122. " I consider this 

 improvement of the blowpipe, one of the most valuable discoveries 

 for the sciences of chemistry and mineralogy that have yet been 

 made." And thus does he modestly claim to his modification th.e 

 whole merit of the discovery; for, it must be observed, he does not, 

 in saying " improvement of the blowpipe," allude to the com- 

 pound blowpipe contrived by me, but to the ordinary blowpipe of 

 the mechanic or mineralogist. Other instances might be adduced; 

 but it is presumed that more than enough has been brought for- 

 ward to show, that if the merit of this invention is to be awarded 

 according to the motto ' suuin aik/uc,' adopted by Dr. Clark, 

 there would be little left for himself and his coadjutors. 



(^ To the foregoing Dr. Hare subjoins some drawings of his 

 compound blowpipe in its different forms, and of some varieties 

 of apparatus which may be used for supplying it with hvdrogeu 

 and oxygen gas, but winch may be readily conceived by those pos- 

 sessing the volinnes of the Phil. Mag. to which he has referred, 

 without our enlarging the present article. We believe it is al- 

 lowed by most men acquainted with tiiis subject, that Dr. Clark 

 has not acted towards Dr. Hare with any over share of honest 

 liberality. 



LVI. Some Account of the Du gong. By S;V Thomas Stamford 

 Raffles, Governor of Sumatra; comviunkalcd in a Letter 

 to Sir EvERAKD Home, Bart. F.P.R.S.* 



My dear Sir, — 1 have now the pleasure of communicating to 

 you the desired information concerning the dugong. At Singa- 

 pore, in June last, I had the good fortune to meet with one of 

 these animals, and Messrs. Diard and Dnvaucel, two French n.'i- 

 turalists, employed under my authority, undertook the dissectic n 

 of it; and have sent a dissertation upon it to Sir Joseph Banks. 

 This docs not interfere with my sending to you, as I promised, 

 an account of it. I was present at the dissection ; and the fol- 

 lowing observations, as far as they go, may be depended upon. 

 I have read them over to Dr. Wallick and General Hardwickc, 

 and they concur in opinion as to the correctness of the descrip- 

 tion. I have the pleasure to acquaint you, that General Ilard- 

 wicke has just now got a small dugong, four feet six inches long,
