NEw-HAvEE. Dec. 6.-The transit of Venus
was carefully watched at the Yale Observatory The
most preparations had been made by Professor
Leonard Waldo and his assistant Professor JS Kersch
ner professor of astronomy in the Franklin and Mar
shall College, of Lancaster, Penn There were five OBJ
servers on duty the helometer at the Yale o0serva
tory and the operations of the complicated instrument
were carefully noted.
Although the observatory building itself was not com
pleted yet by concentrating the energies OF the OBJ
they were able complete the arrangement for
the Photographic and heOmetro observations OF the
transit The photographs were taken with the new
equatorial which had Photographic lens of about ten
feet focus Over one hundred and fifty plates showing
the whole with Venus on it's disk, were secured
These photographs are about onequsrter the
size Of the Government photographs They nave
