640 Proceedings of the Boyal Society 
For these varied and important labours, the Council of the Eoyal 
Society considered Mr Kamsay well entitled to the honour of re- 
ceiving the Neill Medal. The President, addressing Mr Eamsay, 
then said, 
Mr Eamsay, I have much pleasure in delivering to you the Neill 
Medal, and in congratulating you on an honour which you have so 
well deserved. 
At the request of the Council, Professor Piazzi Smyth, Astro- 
nomer-Eoyal for Scotland, gave “ an account of recent measures at 
the Grreat Pyramid, and the deductions flowing therefrom.” 
This address, which was illustrated by specimens, models, draw- 
ings, and stereoscopic photographs, referred chiefly to the four 
months’ labour of the author in the winter and spring of 1864 and 
1865 at the G-reat Pyramid ; where he went with the approval of, 
and also, he thankfully acknowledges, a considerable amount of 
assistance from, His Highness the Viceroy of Egypt. The observa- 
tions then made, comprised measures of length, angle, and heat ; 
and are enough to fill several MS. books, which are being prepared 
for publication. The author, indeed, had hoped to put all these 
foundational facts into the hands of the public before venturing to 
announce any of the conclusions, but was overruled by respect for 
the appeal made to him by the Council of the Society on this occa- 
sion. He trusts however, still, that no one will prejudge the 
pyramid question on hearsay, but wait until they have all the 
instrumental particulars before them.
