          PHOTOELECTRIC OBSERVATIONS OF TX CANCRI

      The eclipsing variable TX Cancri was observed with
the 36 inch reflectors at the Okayama Astrophysical 
Observatory and the Dodaira Station of Tokyo Astronomical 
Observatory on sixteen nights during the winters of 1962-63,
1964-65, 1965-66, 1967-68 and 1970-71. BD +19d2067 was used
as the comparison star. The standard UBV colour filters and
three narrow-band filters (lambda_eff = 4870, 4110, 3940A) were
used. The observed dates are shown in the following table.
