of constructing a large mirror for this observa- 

 tory. A disk of glass 100 inches in diameter 

 and 13 inches thick, weighing 4J tons, has 

 recently been received at our Pasadena shop 

 from the French Plate Glass Works at St. 

 Gobain, France. Much time vpas consumed 

 in filling our order, and it was hoped that the 

 disk would prove suitable. This does not turn 

 out to be the case, however, and another trial 

 must be made. The observatory will experi- 

 ence no financial loss, as the disk had not been 

 accepted. The loss in time will not be very 

 serious, because of the great opportunities for 

 research in unexplored fields afforded by the 

 60-inch reflector. I have no doubt that the 

 difficulties of making a homogeneous disk of 

 these great dimensions will soon be success- 

 fully overcome, and that the Hooker telescope 

 will be ready in time to extend the work of the 

 60-inch reflector into territory which even this 

 powerful instrument can not enter.

BROOKS MEMORIAL 



In the Donovan room of McCoy Hall, Johns 

 Hopkins University, the end of the old and 

 beginning of the new year saw a memorable 

 reunion of men who had worked in contact 

 with Professor W. K. Brooks. Under the 

 guidance of the chairman. Professor S. F. 

 Clarke, many paid tribute to Brooks, the in- 

 spiring teacher, whose life at Williams and at 

 Cambridge was vividly sketched by Professor 

 Edward A. Birge, and whose career at the 

 Johns Hopkins furnished the material for 

 many pleasant recollections' and expressions 

 of esteem and of love by Professors E. B. 

 Wilson, H. W. Conn, H. H. Donaldson, F. H. 

 Herrick, M. M. Metcalf and others who were 

 Brooks's pupils in later years. 



Upon motion of Professor Harrison a com- 

 mittee was appointed to prepare a memorial 

 volume in honor of their master. 



Professor E. L. Mark and thirty-two other 

 zoologists of Harvard, in attendance upon the 

 scientific meetings in Baltimore, wrote to ex- 

 press their " sentiments of highest appreciation 

 for the character of the work of William 

 Keith Brooks." 



It was hoped that the incidents of Professor 

 Brooks's life at Penikese could be made vivid 

 by one who was there with Brooks, but a tele- 

 gram from President David Starr Jordan 

 stated his regret that he could not be present 

 to honor the memory of " the wisest of Amer- 

 ican naturalists." Others were also unable 

 to come to Baltimore. The names of the
