The daily life of the ancient cliff dwellers 

 is exhibited in the new permanent " South- 

 western Indian Hall " just added to the mu- 

 seum of anthropology of the University of 

 California, in San Francisco. Two other 

 phases of aboriginal life are abundantly illus- 

 trated in the same new hall — the town-dwelling 

 .arts, crafts, rites and industries of the Pueblo 

 Indians, and the life of war and the chase led 

 by the nomadic tribes of the Southwest, such 

 -as the wild Apaches, Navajos, Pimas, Papagos 

 and Walapais. The museum is open free to 

 the public daily except Monday, with free lec- 

 tures every Sunday at 3. It has four other 

 large permanent exhibition halls — Egyptian, 

 Greek, Peruvian and Californian — besides 

 ■smaller unit collections. The collections of 

 this museum of anthropology are said to be 

 worth from three to five million dollars. They 

 are the gift to the university of Mrs. Phoebe 

 A. Hearst. The department of anthropology 

 is extending its usefulness by field investiga- 

 tions of Indian languages and customs, by 

 correspondence courses in anthropology, and 

 by sending out to any school that desires 

 traveling loan collections illustrating life 

 among the Indians. 



At the meeting of the Academy of Natural 

 Sciences of Philadelphia, held the 2d inst., 

 the following was unanimously adopted: 



"Whereas, The academy has been infomied by 

 the council of the receipt and adoption of a final 

 report on the centenary celebration and the dis- 

 charge of the committee having charge of it, 



Resolved, That the academy, approving of the ac- 

 tion of the council, desires to express its obligation 

 to the committee and to record on the minutes 

 its thanks for the entirely adequate and satisfac- 

 tory discharge of its duties, resulting in a record of 

 achievement ■which can not fail to be an incentive 

 to those who will celebrate the second centenary of 

 the academy in 2012. 



Bulletin 539 of the Harvard College Ob- 

 servatory, signed by Dr. Edward C. Pickering, 

 the director, states that Titan, the brightest 

 satellite of Saturn, has been found to be vari- 

 -able from a discussion of observations taken on 



60 nights by the late Oliver C. Wendell. The 

 measurements were made with the 15-inch 

 equatorial as described in H.A. 69, Part 1. 

 The light varies regularly from 8.53 to 8.77, 

 when reduced to mean opposition. The aver- 

 age deviation of twelve groups from a smooth 

 curve is =t 0.023. The period as in the case 

 of the eighth satellite, Japetus, is the same as 

 that of revolution. Accordingly, it is probably 

 due, in both cases, to one side of the satellite 

 being darker than the other. Titan is fainter 

 than its mean brightness for only about one 

 third of the time. The minimum occurs near 

 the times of superior conjunction. Erom 

 similar observations, on 96 nights, Japetus was 

 found to vary from 10.40 to 12.18. The maxi- 

 mum brightness occurs very near the western 

 elongation. 



The study of protective coatings for iron 

 and steel, begun by the American Society for 

 Testing Materials in 1903 and continued un- 

 brokenly and with increasing effectiveness to 

 the present time, is described in detail in the 

 reports of Committee E (now Committee 

 D-1), now published in combined form in a 

 single volume by the American Society for 

 Testing Materials. During the first few years 

 of the committee's work, it had more or less to 

 feel its ground, but as soon as definite lines of 

 work became clear to it, this work was taken 

 up and pushed as vigorously as possible, con- 

 sistent with the exercise of conservative judg- 

 ment. The first constructive work the com- 

 mittee undertook was in the application of 

 nineteen different paints on the Havre de 

 Grace bridge in 1906. Since then a great deal 

 of work has been accomplished in the study 

 of white paints, the influence of pigments 

 upon corrosion, linseed oil, soya bean oil, 

 China wood oil, turpentine, definitions of 

 terms used in paint specifications, etc. 

 There is probably no book which con- 

 tains within its covers so much orig- 

 inal work on the subject of paints. Com- 

 mittee D-1, approximately made up, as it is, 

 half of representatives of producing interests, 

 and half of representatives of consuming in- 

 terests, constitutes a body of investigators, 

 unhampered as to any line of investigation it
