which it is believed can be applied to advantage 

 in any laboratory requiring careful eolorimetric 

 determinations. Also the solubility of carbon 

 monoxide in serum and plasma was determined, 

 the amount of carbon monoxide dissolved in 

 the serum proving to have little effect upon the 

 accuracy of eolorimetric determinations. The 

 figures for the solubility of carbon monoxide 

 in serum have also a purely scientific value in 

 the calculation of carbon dioxide in serum and 

 the determination of the hydrogen in concen- 

 tration. 



In addition to these studies on carbon mon- 

 oxide Dr. Yandell Henderson and Dr. W. Hag- 

 gard, as consulting physiologists to the Bureau 

 of Mines, in work done at the Laboratory of 

 Applied Physiology at New Haven, Conn., on 

 the problem of the elimination of carbon mon- 

 oxide from the blood after a dangerous degree 

 of asphyxia, have determined that ventilation 

 of the lungs could be increased from 300 to 

 400 per cent, by adding 6 to 10 per cent, of 

 carbon dioxide to pure oxygen. These investi- 

 gators have also shown that the etfects of car- 

 bon monoxide upon the heart are not specific, 

 but are secondary to general asphyxia and a 

 terminal failure of respiration. Material is 

 now available for a report showing that symp- 

 toms and effects sometimes assigned to chronic 

 carbon monoxide poisoning are in reality due 

 to the effects of benzol and related substances 

 in illuminating gas. This conclusion has a di- 

 rect bearing on the use of mixtures of gasoline 

 and coal distillate in underground locomotives. 



WORLD LIST OF SCIENTIFIC PERIODlCALSi 

 The Conjoint Board of Scientific Societies 

 proposes, if sufficient support is obtained, to 

 arrange for the issue of a world list of peri- 

 odical publications which contain the results of 

 original scientific research, and has entrusted 

 preliminary arrangements to a committee, of 

 which the following are members: Sir Sidney 

 F. Harmer (chairman), Mr. F. W. Clifford, 

 Sir Eichard Gregory, Dr. P. Chalmers Mitchell, 

 Mr. A. W. Pollard, and Professor W. W. 

 Watts, secretary. 



The list will be an octavo volume contain- 

 ing, in alphabetical order, the titles and places 



1 From Nature. 



of publication of all such periodicals in exist- 

 ence on January 1, 1900, and of all issued 

 after that date. 



Libraries in London, Oxford, Cambridge, 

 Edinburgh, Dublin and Aberystwyth which take 

 in these periodicals will be indicated in the 

 list, and, wherever possible, at least one li- 

 brary in the United Kingdom will be indicated 

 for each title. 



The copies will be printed on one side only 

 to facilitate alterations and additions. 



The objects of the proposed volume are : 

 (1) To supply as nearly as possible a com- 

 plete list of current scientific periodicals; (2) 

 to indicate, where possible, at least one library 

 where each periodical is taken; (3) to form a 

 basis for cooperation between libraries, so that 

 both the number of duplicates and the list of 

 periodicals not taken in may be reduced; and 

 (4) to enable each library to use the list for 

 its own purposes, by placing a mark against 

 the title of each periodical it possesses, by cut- 

 ting up for a card index, etc. 



The trustees of the British Museum, recog- 

 nizing the importance of this work to scien- 

 tific research and bibliography, have consent- 

 ed to allow the compilation to be undertaken 

 by the staff of the Museum. They are unable, 

 however, to defray the cost of printing and 

 publication. 



Although the value of a list of this kind to 

 libraries and scientific societies would be very 

 great, it is scarcely possible that the produc- 

 tion of so costly a work would be entertained 

 by a publishing firm as an ordinary commercial 

 enterprise. If, however, a suflBcient number 

 of libraries and institutions agree in advance 

 to purchase one or more copies, when issued, 

 the compilation of the list will be put in hand 

 at once. Already a large bulk of material has 

 been collected in the British Museum by vari- 

 ous societies and by the Conjoint Board. 



I shall be glad to receive by January 31, if 

 jjossible, the names and addresses of institu- 

 tions or individuals who will support this pro- 

 posal by undertaking to subscribe for one or 

 more copies of the list. The price per copy 



will be 21. 2s. net.
