Notice from Dr. Robert Hare. 39] 
who is employed to-exhibit the Aydisdkpoen, microscope at the 
Adelaide Gallery, London, asserted that I had ‘accomplished the ee 
fusion, of which mention has been above made, by means of a 
blowpipe of his seu ait which I had purchased while in — 
London. 
The opinion which I am obliged to entertain of an individual 
capable of this groundless assertion, would cause me-to consider 
him unworthy of notice, had not his misstatement been made 
before an assemblage which I most highly esteem, and had he 
not been honored by a premium for his pretended invention by a 
respectable British Society. 
_ The blowpipe which is thus falsely alleged to have béen used 
by me, differs immaterially from one of which I published an 
engraving and description in the American Journal of Science for 
1820, vol. u, p. 298, being a modification of that. originally con- 
trived by. me and republished in Tilloch’s 8 Philosophical Magazine, 
vol. xiv, for 1802. 
Between the instruments described i in these cubleations or in 
the Franklin Journal, and that employed by Maugham, the only 
difference worthy of notice is, that the latter is near the apex bent 
- so as to form an acute angle, and is thus rendered suitable for 
directing the flame upon a revolving cylinder of lime. 
Although I purchased of Newman a blowpipe bent as described, 
with an apparatus attached for holding’ and turning a cylinder of 
lime, I have never made any use of it, having for the purpose of 
subjecting lime to the flame, found my modification above referred 
to as described in this Journal, preferable. It only required the 
jet pipe to be directed upwards in an angle of about forty five 
degrees with the axis of the lime cylinder. _ 
I do not consider the form of my blowpipe minployed by Mr. 
M. as qualified for the fusion of any metal. 
It is remarkable that an apparatus of eacmaoters employed by 
Maugham at the Adelaide Gallery for the supply of the gases for 
the blowpipe differs but little from the apparatus proposed for the 
same purpose in my communication above adverted to, and pub- 
lished nearly twenty years ago. 
However the process by which 1 have lately extended the power 
of the peeun-sxogen blowpipe may differ from those to which I 
had previously resorted, it differs still more from that modification 
tham has claimed as his own.
