XXXII. Obfervations made at Leiceftcr on 
the "Tra 7 'iftt of Venus over the Sun, June 3, 
1769. By the Revere 7 id Mr. Ludlam, 
Vicar of Norton, near Leicefler. 
Head Nov. 1 6, i H E telefcope, ufed for viewing the 
1769. planet, was made by Mr. Dollond, 
with a triple object glafs of 33I- inches focal diftance, 
and was found by experiment to magnify 54 times. 
The clock was firmly fixed ; its pendulum rod was 
made of wood. The tranfit telefcope was not accu- 
rately adjufted either to the meridian or horizon, but 
the tranfits of the Sun and of Bootis regiftered 
below are fufiicient to fiiow the rate of the going of 
the clock, and the correfponding altitudes of the 
Sun, its error a few days before the tranfit of the 
planet j whence the necefiTary redudlion of the time 
then Ihewn by the clock to apparent time may be 
eafily derived.
