objects were successful only in one case (Karo,.ewo, Olstyn province) where the
work was performed by a team of~students, technicians-geodesists. 'a,e experi-
~-ence of conducting educational-,pradtice for the 1st course, accumulated for
many years, has shown that a student team should consist of 6 people, and mixed
teams should not be admitted.~The amount of work performed by female! teams
should be less-by 20 25%, than that of male teams.

between Warsaw and the Antartic . The first --point-- was -located in - tht- Institute

Ocean according Ito the measurement.s.of.the second Russian expedItIon in 1956/57.

had been used from 1956
to 59 for a gravimetrio survey of-Poland,.with an aacuraay of + 0.2 mgal. The

TQC (Pontoise).- In this manne;r, three stations - GBR,--ROR, FYP/TQC --were re-
ceived at the two points. For the reduction of the pendulum periodki, the oWac-
teristies of the-apparatus as-determined during the-gravimetric surt-ey-of-Poland
were taken in-to consideration. Only the thermal coefficiehts were determined
speoially for temperatures-between-7 and + 35Q-C.- The-following results were-
