Author: Seward, A. C. (Albert Charles)

Seward, A. C. (Albert Charles)

Paleobotany

To Dr Henry Woodward of the British Museum I am indebted for the loan
of the woodblocks made use of in figs. 10, 47, 60, 66, and 101, and to
Messrs Macmillan for the process-block of fig. 25.

For the photographs reproduced in figs. 15, 34, 68, 102 and 103 I owe
an acknowledgment to Mr Edwin Wilson of Cambridge, and to my friend Mr
C. A. Barber for the micro-photograph made use of in fig. 40.

In conclusion I wish more particularly to thank my wife, who has drawn
by far the greater number of the illustrations, and has in many other
ways assisted me in the preparation of this Volume.

In Volume II the Systematic treatment of Plants will be concluded,
and the last chapters will be devoted to such subjects as geological
floras, plants as rock-builders, fossil plants and evolution, and other
general questions connected with Palaeobotany.
