rifice himself for the good of his companions. Indeed, his 

 presence on an expedition was an assurance that it would 

 be both a pleasant and a successful one. 



" Dr. Allen was elected a member of this Society in 1878, 

 at its second meeting, and has always taken an active part 

 in its proceedings, serving as Treasurer from 1889 to 1890. 

 The results of his natural history researches were always 

 presented before the Society, and his interest and attain- 

 ments in every branch of science permitted him to discuss 

 almost any subject which has come before us 



" We feel, therefore, that in Dr. Allen's death, the Soci- 

 ety has parted with a member it could ill afford to lose, 

 and as your Committee we know that we are voicing the 

 sentiments of the Society, when we express our sincere 

 grief at the death of one who ever had the best interests of 

 the Society at heart.

Mr. L. M. Loomis presented a paper entitled " Variabil- 

 ity in the Occurrence of Transient Migrants." [See 

 "Auk," Vol. xi., 1894, pp. 26-33.] 



Mr. Loomis also read a paper entitled " Facts Concern- 

 ing Migration in the Southern Hemisphere, Gleaned from 

 Sclater and Hudson's 'Argentine Ornithology.' " The ob- 

 servations recorded in this work reveal that the same 

 causes of migration exist in temperate South America as 

 in temperate North America, and that similar movements 

 take place in both regions. The height of the movement 

 toward the equator occurs in Argentina during February 

 and extends through March and into April. The migration 

 to the breeding-grounds in the direction of the South Pole 

 takes place chiefly in August, September, and October. 

 In addition to the migration of endemic species, there is a 

 migration thither of birds breeding in North America.
