Brome Itaplement found near Gurrie, Mid-LofMan. 105 
therefore, of their antiquity. I also wished information as to the 
hardness of the metal of which this instrument was composed, 
and its capability of having once had a fine and sharp edge. 
Dr Macadam filed a portion of the metal from the back of the 
straight stalk or handle, where it has since unfortunately been 
broken; and has kindly favoured me with the follov/ing notes, 
giving the result of his examination : — 
" I have examined the bronze implement found at Kinleith, 
near Currie, and find its composition to be : — 
Copper (with trace of lead), . . 92-97 
Tin, ..... 703 
100-00 
It is therefore a true bronze, with less than the average proportion 
of tin. 
"The metal .was hard under the file, and it might have had an 
edge when new. I have no doubt the rust is a double carbonate 
and oxide of copper, but I do not know if we can connect the 
characteristic appearance of this rust with any peculiarity in the 
composition of the alloy. I would be more inclined to consider 
that the circumstances in which the implement was placed in 
regard to moisture and atmospheric action, would play an important 
part in the formation of the various coloured tints." 
This being the concluding meeting of the Session, votes of thanks 
were given to the Office-bearers, and the Society adjourned to the 
commencement of next winter session.
