as the necks were fitted to their wooden Blocks 
with a refinous cement without glafs hoppers; fo 
that when the globes, from their being rubbed, had 
warmed the cement, if an odour of the matter con- 
tained in the glafs had been perceptible, it might 
have been urged, that it came through the cement

June 12, 175" i, there met me at my houfe, In 
order to make trial of the effedts of thefe sjafTe?, 
Martin Folkes Efq; Prefident, Nicholas Mann Efq; 
Vice-prefident, Dr. Mortimer and Peter Daval Efq; 
Secretaries, Mr. Canton, Fellow of the Royal Society;

the prime condudtor were but weak; but upon rubbing 
the globe, firft with the cufhion, which I have ufually 
for that purpofe employed, and afterwards with red 
leather, the fnaps were much fironger ; and Mr. Can- 
ton, as well as another gentleman prefent, were 
cledtrifed
