In oceanography, tidal, ciUTent, meteorological, and magnetic
observations were made wherever possible, and serial temperatures
and water samples were secured down to 1000 fathoms. The
charts were everywhere examined and corrected, and the existence
of any shallow connecting bank between India and Madagascar
was disproved. About 150 dredgings were run down to 900
fathoms, and plankton was extensively collected by closing and
other nets down to 1200 fathoms. The reef faunas and floras
were especially collected in the Chagos and at Coetivy in view of
the distribution of marine organisms, and the islands everywhere
were carefully examined, their land animals and plants being
collected as thoroughly as possible.

of the developmental changes in Zoogloea, of which the following is
tlie author's abstract :
—
Masses of Zooglcea in their early stage were first shown, in which
the constituent Bacteria were plainly recognizable. The growth of
the masses, their alteration in appearance and in reaction to staining
fluids, together with the progressive segmentation which they
undergo, were revealed by other specimens. Segmentation was
shown to progress till minute spherical or ovoidal units were produced.
During the flrst 3-5 days, while these changes are
