1878. ] Proceedings of Scientific Societies. 337 
— Thanks to the interest taken in the young and vigorous 
‘Academy of Science at Davenport, Iowa, by one or two of the 
citizens and members, a new building well adapted to the wants 
of the Society has just been finished, one or two meetings having 
been held in it. The second part of its Proceedings will appear 
at an early date. 
— Capt. Howgate’s bill for establishing a Polar Colony has met 
with a favorable hearing by the Congressional committee, and it 
seems most probable that Congress will appropriate $50,000 for 
the undertaking, which promises so much for the advancement of 
Polar research. ' 
_— The third session of the Summer School of Biology will 
be opened at the Museum of the Peabody Academy of Science, 
alem, Mass., beginning July 5th, and continuing six weeks. A 
lecture will be given each Monday, Tuesday, Wednesday, Thurs- 
day and Friday at 9 A. M., the remainder of the time to be given 
to laboratory work and demonstrations, as it is designed to make 
the course a practical one, so that teachers may learn the method 
of study and teaching in Natural History. During the present 
session special attention will be given to Entomology, the study 
of Spiders and Crustacea, as well as the Anatomy of Vertebrates, 
and the study of Animal Tissues. 
Instruction in Zoology will be given by Dr. A. S. Packard, Jr., 
with the assistance of Messrs. Charles Sedgwick Minot, James H. 
Emerton, and J. S. Kingsley. Mr. Minot will lecture on Histology 
and on the Anatomy of Vertebrates. Mr. Emerton will lecture 
on Spiders, Scorpions and Mites, Mr. Kingsley on the Crustacea, 
and Dr. Packard will give a course of lectures on the lower ani- 
mals and the Insects. Rev. Dr. Bolles will give a series of six 
afternoon lectures on Microscopy, at 3 P. M., beginning July 12. 
For further information apply to A. S. Packard, Jr., Director, 
Peabody Academy of Science, Salem, Mass.

Boston Society or Natura History.— March 6. Mr. S 
H. Scudder made a communication on Prodryas, a new fossil 
butterfly from the tertiary beds of Colorado. 
On March 20, Prof. A. H. Niles read some notes upon the 
erosive power of the glaciers and sub-glacial streams of the © 
Alps, based on a summer's exploration. He took the view that 
ism. 
April 3d.—Prof. B. G. Wilder exhibited living specimens of 
Amia, and spoke of its erial respiration, and Mr. S. H. Scudder 
remarked on the early life of some tertiary insects, and particu- 
larly on the eggs of a fossil Corydalus (hellgramite).
