the use of barium lines in the neighborhood of 4 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 Angstrém; and the 
general adoption of the plan of measuring position angles around 
the sun’s limb from the north to the east.” *** The last article of 
the tenth volume of the Memoirs was published in 1911. 
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.*” 
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
