thing,
however, to find a fenestrated arrangement of the great omentum which
shows that its layers have been completely obliterated in many places.

In those animals, such as the rabbit, in which the tests are sometimes
in the scrotum and sometimes in the abdomen, the communication between
the peritoneum and the tunica vaginalis remains throughout life.

FOOTNOTE:

by fusion, but by a dragging away of the posterior layer of the great
omentum from the dorsal wall of the abdomen.

COEN, JAN PIETERSZOON (1587-1630), fourth governor-general of the Dutch
East Indies, was born at Hoorn, and spent his youth at Rome in the house
of the famous merchants the Piscatori. In 1607 he sailed from Amsterdam
to the Indies as second commercial agent, and remained away four years.
He had proved so capable that in 1612 he was sent out a second time at
the head of a trading expedition. In the following year he was made a
councillor and director-general of the East Indian trade. Afterwards he
became president at Bantam, and on the 31st of October 1617 he was
promoted in succession to Laurens Reaal to the post of governor-general.
To his vigour and intrepidity the Dutch in no small measure owed the
preservation and establishment of their empire in the East. He took and
destroyed Jacatra, and founded on its ruins the capital of the Dutch
East Indies, to which he gave the name of Batavia. In 1622 Coen obtained
leave to resign his post and return to Holland, but in his absence great
difficulties had arisen with the English at Amboina (the so-called
massacre of Amboina), and in 1627 under pressure from the directors of
the East India Company he again returned as governor-general to Batavia.
In 1629 he was able to beat off a formidable attack of the sultan of
Mataram, sometimes styled emperor of Java, upon Batavia. He died the
following year.

COENACULUM, the term applied to the eating-room of a Roman house in
which the supper (_coena_) or latest meal was taken. It was sometimes
placed in an upper storey and reached by an external staircase. The Last
Supper in the New Testament was taken in the Coenaculum, the "large
upper room" cited in St Mark (xiv. 15) and St Luke (xxii. 12).
