[[/underlined]] 4. throw much and perhaps decisive light on the question, still unanswered: Whence did the ancient Chinese obtain their supplies of metal, and especially copper? At all events it will, I feel, add materially to the value of this report if I record here the results of that spectrographic examination which Mr. Morris Slavin, of the U. S. Bureau of Mines, kindly made [[superscript]] (3) [[/superscript]] of ---------------------------------- (3) At the instance of Dr. W. F. Foshag, of the Department of Mineralogy at the U. S. National Museum, to whom I have already made my acknowledgments (see page 417 of the text). ---------------------------------- the two apparently very early little specimens of Chinese bronze that Mr. Wilson discovered at the prehistoric Shih Hsiang site (see pp. 416 [[underlined]] sqq. [[/underlined]] of the text, and pl. 7 [[strikethrough]] 3 [[/strikethrough]] , fig. 2). Mr. Slavin's findings are as follows: [[three columns headings follow, each one separately underlined]] Composition Flat object. Pointed object (awl?). Arsenic, .05%, .05%. Cobalt, .01%, .01%. Copper, principal, principal. Chromium, .01%, .01%. Gold, .001%, .005%. Iron, 1%, .05%. Lead, 1-5%, 1-5%. Nickel, .01%, .01%. Silver, .1%, .1%. Tin, 1-5%, 1-5%. Thus it will be seen at once that these two little metal objects are of practically identical composition, and are therefore derived from the same region; and that they are indubitably of bronze. The percentages of tin and lead are the same in both, and are incidentally considerably
