way at Mount' Wilson and Mount Lowe, under the supervision of Prof. 

 Hale of the Terkes Abservatory and his associate astronomers. 



This is justly regarded as a matter of congratulation, not only 

 on behalf of the Astronomical Section, but as Tvell on the part of the 

 entire Academy and the community at large. 



Chairman Knight having arrived, with th* speaker of the evening, 

 the chair was surrendered to him and in the course of certain felicitous 

 remarks, he introduced Bishop Warren of the Methodist General Con- 

 ference. The Bishop, who is the author of some works on astronomy, 

 and a man of broad culture and accurate scientific attainments, pro- 

 ceeded to entertain and instruct the Section in a most delightful 

 manuer. 



In eloquent terms he depicted the fascinating beauties of astronomy, 

 intermingling with the serious and the severely scientific much of his 

 dharming wit. 



At the close of Bishop Warren's address, the chairman presented 

 the subject of La Place's "Invariable Plane," indicating the views 

 of certain eminent mathematical astronomers in regard thereto, and 

 illustrating the same by diagrams. 



After some discussion of this topic by the chairman and Mr. 

 Baumg-ardt, the meeting adjourned.

BIOLOGICAL SECTION. 



The meeting was called to order by the chairman. The minutes of 

 the last meeting were read and approved. 



A brief report on the Trichina spiralis illustrated by a microscopic 

 specimen was presented by Mr. Whiting. 



Prof. Ulrey reported that Prof. LTngo de Pries was going to carry 

 on extensive investigations at the L'niversity of California during the 

 coming summer, on the problem of the Origin of Species. 



Prof. A. B. LTlrey was elected chairman and C. A. Whiting was 

 elected secretary. 



The lecture of the evening was given by Dr. Leonard, City Bacteriol- 

 ogist, on Some Bacilli related to the Baeilli of Tuberculosis. 



The lecture was instantly interesting and highly practical. The 

 lecturer pointed out the fact that there are certain barteria which live 

 upon grass whose staining reactions are the same as the bacillus of 

 tuberculosis. The speaker expressed the opinion that the bacilli of 

 human tuberculosis and bovine tuberculosis are identical, but stated 

 that further investigation is necessary to positively prove their identity. 



A great many questions bearing on the pra'ctical side of the work 

 of the bacteriologist were asked and were clearly answered by Dr. 

 Leonard. 



About forty-five members and visitors were present. 



The Section adjourned to hold its final meeting for the year on the 

 second Mondav in June.
