nickel in that form as compared with iron in that form, for the pro- 
duction of galvanic currents. Several years later, in order to in- 
crease what is called the magnetic quality of nickel, which you no 
doubt know is much feebler than that of steel, I had a series of bars 
made of alloys of nickel and tungsten, as, it being known that 
tungsten increases the magnetic quality of steel, I thought it might 
act the same with nickel. With those bars I investigated and found 
that the hypothesis which I had formed was correct, and I had a 
series of those made with progressive increases of the alloy of tung- 
sten, and the result of all that has been published and I will not de- 
tain you with it. Those series of bars unfortunately were lost, as I 
sent them to the Exhibition at Paris, and they were never returned. 
One of the ship’s compasses which were magnetized, I think in the 
year 1874, I lately investigated and found that the magnetism re- 
mained apparently about as strong as it was in the beginning, show- 
ing that the magnetism of a magnetic needle composed of pure 
nickel is permanent. 
President Fraley then made the following closing address : 
The programme for the celebration of our 150th anniversary is 
now literally completed. I cannot say farewell to you, for what I 
have felt here in meeting so many new and so many old friends does 
not permit me to entertain the thought that I must part from them. 
All I can say is that we have been signally blessed in this celebra- 
tion. We have not only had a perpetuation of good words and 
perpetuation of good cheer, but the beginning of friendships which 
will last certainly so long as we are permitted to tread the earth. I 
thank you all for what has been given to us upon this occasion, hop- 
ing, as Prof. Barker has expressed the hope, that the good work for 
the promotion of science will go on for a series and series and series 
of 150 years; that not only our own institution may take its part 
in the great work of promoting useful knowledge, but all the insti- 
tutions that are represented here and all others who are not and 
have tendered their congratulations will equally continue at work, 
and that those who come, I will say 150 years hence, but I will 
shorten the period and say all those who may come here fifty years 
hence, will find the old hall standing on its foundation with accu- 
mulated treasures within its walls and precious memories encir- 
cling the hearts of all those who have been in the past members
