45 6 LETTER S. 
porting an Aftronomer in Cairo, which is favoured 
with the fereneft horizon, a conftant mild climate 
and clear Iky ; and thefe would, I imagine, afford 
opportunities for eafy and conftant obfervations. He 
might, perhaps, have fome trouble from the inha- 
bitants, on account of their fuperftition, but even 
this, he might foon get over. He would find 
learned Arabs, powerful men, who love and ftudy 
Aftronomy in their manner, whofe proteftion 
would defend him from the people, and the 
expence would not be very great.
