Arr. XIUI—Strictures on a publication, entitled Clark’s 
Gas Blowpipe ; by Ropert Hare, M. D. Professor of 
Chemistry in the medical department of the University of 
Pennsylvania, and the real inventor of the cilab sat or 
hydro-oxygen blowpipe, in that safe and efficient form by 
which the fusion of the most refractory earths, and the vola- 
tilization and combustion of Platinum was first accom- 
plished. 
Hos ego versiculos feci, tulit alter honores, 
Sic vos non vobis nidificatis aves 
Sic vos non vobis melificatis apes, 
Sic vos non vobis fertis aratra Boves.

{In the year 1802, in a memoir republished in the 14th 
Vol. of Tilloch’s Philosophical Magazine, London, and in 
the 45th Vol. of the Annales de Chimie, I had given the 
fationale of the heat produced by the combustion of the 
aeriform elements of water, and had devised a mode of ig- 
niting them free from the danger of explosion. I had also 
Stated in the same memoir that the light and heat of the 
flame thus produced were so intense, that the eyes could 
Searcely sustain the one, nor the most refractory substances 
resist the other, and had likewise mentioned the fusion of 
the pure earths and volatilization of the perfect metals as 
among the results of the invention. 
Subsequently in the first part of the 6th Vol. of American 
Philosophical Transactions, an account of the fusion of 
— and the volatilization of Platinum, was published 
y me. '
