Otley Beyer, Dr. David P. Barrows, now of the University of California, along with assistance from the late Professor Ferdinand Blumentritt, of Leitmeritz, Dr. C. M. Heller, of Dresden, and the authorities of the British Museum, Congressional Library, America Institute of Berlin, University of California Library, and the Hongkong and Shanghai public libraries and Royal Asiatic Society branches. It is due the printer, Mr. Frederic H. Stevens, manager of E. C. McCullough & Co.'s press; Mr. John Howe who figured out a sufficient and satisfactory paper supply despite the war-time scarcity; and Superintendent Noronha, that after the first vigorous protests against departures from established printing-house usages, they loyally co-operated in producing a book whose chief consideration has been the reader's use. Paper, ink, special press-work and the clear-cut face chosen for the hand-set type have combined to get a great deal more matter into the same space without sacrifice of legibility; putting minor headings in the margin has been another space-saver which as well facilitates reference, while the omission of the customary blank pages and spaces between articles has materially aided in keeping down unnecessary bulk. Printed in the usual style this book should have run over twelve hundred octavo pages as against its under two-thirds that number of a but slightly larger page. And finally, my colleague, Professor Conrado Benitez, besides furnishing promptly his part of the manuscript has been chief adviser and most zealous in carrying out our joint plan. Austin Craig.
