was held in the rooms of the German Turn- 

 verein on Tuesday evening, January 28. Dr. 

 James Locke, of Tale University, addressed the 

 Society on ' Some Recent Problems in the Sys- 

 tematization of Inorganic Compounds.' The 

 paper was a resume of some work on the solu- 

 bility of various alums, and of certain double 

 sulphates, which has been in progress for sev- 

 eral years in the laboratories of the Sheffield 

 Scientific School. It was shown that when 

 the solubility of the alums of aluminium, 

 vanadiiim, chromium, and iron with ammo- 

 nium, sodimn, potassium, cssium, rubidium, 

 and thallium is expressed in gram-molecules 

 per liter of water as a function of the atomic 

 weight of the trivalent metal, a figure is ob- 

 tained in which the straight lines connecting 

 the solubility of any two trivalent metals with 

 successive univalent metals meet in a point, if 

 prolonged. It was assumed that the points of 

 solubility stand in fixed mathematical ratio to 

 one another, and it was shown that if the dif- 

 ference of the solubility of the alums of a 

 trivalent metal with two aUi;ali metals is called 

 the increment of solubility of the latter, then 

 the ratio between the increments of solubility 

 of the corresponding alums of two trivalent 

 metals for any two aUsali metals is a constant. 

 This general law was amply confirmed by the 

 experimental results, and it was shown that 

 the solubility of new alums could be pre- 

 dicted with considerable accuracy. 



Dr. B. S. Merigold, of the Worcester Poly- 

 technic Institute, read a paper on 'Some He- 

 cent Work on TJranivim,' in which he described 

 the method and apparatus for obtaining pure 

 anhydrous uranous bromide and the use of 

 this substance for the determination of the 

 atomic weight of uranium. The mean value 

 of two sets of experiments was 238.52, about 

 one unit lower than the recent values of Zim- 

 merman. Henry Fay,

A MEETING was held on January 27. The 

 chairman. Professor Farrand, after opening 

 the meeting, called on General James Grant 

 Wilson to preside. 



J\Ix. F. S. Dellenbaugh explained his under- 

 standing of the location of the historic towns 

 and ' nations ' of the Eio Grande valley in New 

 Mexico prior to 1630. This differs radically 

 and entirely from the present accepted ar- 

 rangement. He maintains that the location 

 of Tiguex, rather than Cibola, is the key to 

 the correct solution of this problem, and from 

 strong evidence derived from Benavides, Espe- 

 jo, Castaneda and others, he locates Tiguex 

 near San Antonio station. The site at Ber- 

 nalillo, for this central town, so long advo- 

 cated by Bandelier and his followers, he 

 declares is impossible. With Tiguex at San An- 

 tonio station, the famous 'Seven Cities of Ci- 

 bola,' which Bandelier placed on the site of 

 modern Zuni, are thrown instead into south- 

 western New Mexico, either on the Gila near 

 Old Camp Vincent, or Old Fort West, or be- 

 tween these and the Florida Mountains, with 

 the balance in favor of a site on the Gila. 

 Cicuye, instead of being at Pecos, was appar- 

 ently a Tompiras town, either what has been 

 erroneously called Gran Quivira or some vil- 

 lage of that locality. The Braba of Coronado 

 would fall in the vicinity of the present Co- 

 chiti, instead of at Taos, and Tusayan instead 

 of being at the Moki Towns, would fall in its 

 position 20 leagues (50 or 60 miles) northwest 

 of the position of Cibola. 



Mr. Harlan I. Smith presented a paper on 

 the 'Hauptman Earthwork,' in Ogemaw 

 County, Michigan. The discovery of this 

 earthwork was first announced by him in 

 Science, June 21, 1901 (p. 991). Personal ob- 

 servation in July enabled him to correct its 

 location somewhat. It is on Section 33 or 34, 

 or both, T. 22, N. (instead of 21), E. 1, E. It 

 was found to lie in a lumbered pine area, and, 

 unlike most such earthworks, far from any 

 watercouj-se. It is covered by dense under- 

 growth and fallen timber. It is composed of 

 a rounded embankment of earth, about 2 feet 

 high and 12 feet wide, encircling an area about 

 197 by 177 feet; outside this is a ditch, 2 feet 

 deep, 6 feet wide at the top, but narrowing 

 towards the bottom. Signs of another em- 

 bankment were seen outside the ditch, and 

 within the enclosed area were several hum- 

 hocks which may prove to be mounds or sim-
