the use of barium lines in the neighborhood of a 5800, where 

 sharp iron lines are not sufficiently numerous for standards; 

 the extension of the system of standards of the second order to 

 shorter and longer wave-lengths; the measurement of standards 

 of the third order by concave gratings at various cooperating 

 institutions; the use of the name International Angstrom (I. A.) 

 for the unit on which the system of standards of the international 

 system is based; the publications of the report of the sun-spot 

 spectrum committee and of the cooperating observers in the 

 next volume of the Transactions of the Solar Union; the con- 

 tinuation of visual observations of spot spectra in accordance 

 with a revised and extended scheme; the preparation of a gen- 

 eral catalogue of the lines in the photographic spectra of sun- 

 spots; the preparation of a new photographic map of the sun- 

 spot spectrum on a scale of 5 mm. to the Angstrom; and the 

 general adoption of the plan of measuring position angles around 

 the sun's limb from the north to the east." 109 The last article of 

 the tenth volume of the Memoirs was published in 191 1. 



A new trust fund was placed under the control of the Acad- 

 emy in 1911 when Sir John Murray presented the sum of $6,000 

 to establish a gold medal to be known as the " Alexander Agassiz 

 Medal," and to be awarded " to scientific men in any part of the 

 world for original contributions to the science of oceanography." 

 The following year the Academy, upon recommendation of a 

 special committee, accepted a design for the medal prepared by 

 Mr. Theodore Spicer-Simpson. 110 



The vertebrate section of the committee on paleontologic 

 correlation submitted a second and final report in 1912 from 

 which it is learned that with the aid of grants from the Bache 

 Fund, amounting to $1,000, it had prepared and published three 

 " correlation bulletins," entitled respectively " Plan and Scope," 

 " Fossil Vertebrates of Belgium," and " Patagonia and the 

 Pampas Cenozoic." Lists of North American fossil vertebrates 

 were also prepared, and matter relating to correlation was also
