SCIENCE 



All 



series of two, the largest eye being common to 

 both series. All these eyes are complete in all 

 their parts (lens, retina, etc.), though difl'ering 

 greatly in size, development of optic nerve and 

 degree of external abstriction. All are internally 

 conipletelj' occluded except the least developed, 

 which still connects by a lumen with its " parent " 

 eye. The growth is orderly in that it secures (a) 

 the same axial orientation, ( 6 ) the same polar 

 orientation, (c) freedom from mutual interrup- 

 tion of vision, (d) nearly maximum compactness. 

 No other possible arrangement secures all these. 

 The mass of tissue in the group is greater than 

 in the normal eye. The case is unique in the 

 literature. The possibility that it represents not 

 proliferation but unequal development of the frag- 

 ments of a broken-up milage is admitted, but re- 

 jected as a probability. If a true case of repeti- 

 tive proliferation of such specialized structures as 

 these eyes, then near analogies are lacking.

THE ASSOCIATION OF OFFICIAL SEED 

 ANALYSTS 



The second annual meeting of the Association 

 of OfBcial Seed Analysts was held in Boston, 

 December 28-29, 1909, in connection with the 

 meeting of the American Association for the 

 Advancement of Science. 



Agricultural colleges, experiment stations and 

 state departments of agriculture in twelve states 

 and the Canadian and the United States depart- 

 ments of agriculture were represented. 



Three papers were presented as follows: 



" The Effect of Alternating Temperature on the 

 Germination of Seeds," by W. L. Goss, U. S. 

 Department of Agriculture. 



" Importance of Uniform Methods of Seed Test- 

 ing," by A. D. Selby, Ohio Agricultural Experi- 

 ment Station. 



"The Sale of Adulterated Farm Seeds in the 

 United States," by E. Brown, U. S. Department 

 of Agriculture. 



The greater part of the time of the meeting was 

 devoted to consideration of the reports of the 

 committees on methods of seed testing and on 

 legislation. The report on methods of seed testing 

 for purity was adopted as official by the associa- 

 tion and that on germination as provisional. The 

 report on state legislation was adopted and the 

 secretary was instructed to prepare both reports 

 for publication.

SOCIETIES AND ACADEMIES 



THE THIRD ANNUAL MEETING OF THE ILLINOIS 

 STATE ACADEMY OF SCIENCE 



In attendance, number and character of papers 

 presented, and in the general spirit of enthusiasm 

 and interest, the meeting at Urbana, Felaruary IS 

 and 19, is regarded with great satisfaction by 

 those who had the good fortune to be present. 



More than one hundred new members were 

 elected, so that now the academy, while but three 

 years old, has something more than four hundred 

 names enrolled on its list — a fact which speaks 

 well both for the enthusiasm and the spirit of 

 helpfulness of Illinois men of science, and which 

 repudiates the idea that men of science are 

 recluses. 



About one hundred and fifty people were present 

 at the various meetings. 



The program was as follows: 



"Dr. A. W. French," In Memoriam, A. R. Crook. 



" A Needed Piece of Work in the Interest of 

 our Young Investigators in Biology," T. W. Gallo- 

 way. 



" The Vegetational History of a Blowout," H. 

 A. Gleason. (Lantern.) 



'■ Recent Habitat Changes in the Illinois River," 

 Chas. C. Adams. (Lantern.) 



•' Forest Successions on Isle Royale," Wm. S. 

 Cooper. (Lantern.) 



" An Ecological Study of the Fish of a Small 

 Stream," Thomas L. Hankinson. 



Address of welcome by the president of the 

 University of Illinois. 



Presidential address — " Relations of the Illinois 

 Academy of Science to the State," Stephen A. 

 Forbes.
