 University of West Virginia; Geo. S. Huntington, M.D., New 

 York City. Professor of Anatomy. College of Physicians and Sur- 

 geons ; Peter J. McCourt, M.D., New York City ; Middleton 

 Michel. M D. , Charleston, S. C, Professor of Physiology, Medi-

 etc., London, England, Demonstrator of Anatomy, St. Thomas's

 M.D., Assistant Demonstrator of Anatomy, University of Penn- 

 sylvania. 



The executive committee, through the secretary, reported that 

 the circular in regard to information concerning the Negro race 

 ■was nearly ready. 



The following papers were then read : 1. Crania of the Ceta- 

 cea. 2. The human lower jaw. Dr. Harrison Allen, University 

 of Pennsylvania. These two papers were illustrated by speci- 

 mens and discussed by Professor Herrick and by Professor Geo. 

 Macloskie of Princeton University. 3. History of the develop- 

 ment of bone-tissue. Illustrated by microscopic slides. Dr. Carl 

 Heitzmann, New Yoi-k ( ity. Discussed by Professors Macloskie 

 and William Libbey, Jr., of Princeton Univeisity. 



The following quotation is an extract from Dr. Allen's presi- 

 dential address: " It is now four year* since the Association of 

 American Anatomists was founded, with a list of filteen mem- 

 bers. Many were the objections raised when it was proposed 

 to organized a new society. Eminent professors declared that 

 it was not needed; others, while sympathizing with its objects, 

 were convinced that the list of members would be so small that 

 it would be a difficult matter to fill the necessary offices. The 

 fact that an active membership exists of ninety-four persons, 

 representing twenty two States, the District of Columbia and 

 the United States army, sufficiently meets both the above-men- 

 tioned objections. It tells us unmistakably that the society is 

 needed, and that not only are the offices filled, but that the as- 

 sociation is recognized as a devoted band of students whose 

 activity compares favorably with that of other scientific organiz- 

 ations. 



" But the work thus far accomplished is but the harbinger of 

 what it is hoped may be undertaken. An attempt at co-opera- 

 tion between the American Anatomists is to be brought before 

 you at this meeting. The executive committee will present a 

 plan by which observations on the anatomy of the Negro shall 

 be entered upon. It is earnestly hoped that every teacher and 

 demonstrator of anatomy in the country, whether a member of 

 this society or not, will assist its committee in accumulating ob- 

 servations on this class of subjects."

 Allen. 6. Observations on the psoas parvus and pyramidalis. A 

 study of variations. Dr Thomas Dwight, Harvard Medical School. 

 7. Significance of percentages in reversions in human anatomy.

NOTES ON THE OCCURRENGE OP RUBELLITE AND 

 LEPIDOLITE IN SOUTHERN CALIFORNIA. 



BY HAROLD W. FAIRBANKS, BERKELEY, CAL. 



The work of the California State Mining Bureau has recently 

 brought into notice a very interesting association of mmeials in 

 San Diego County, California. The most important of these are- 

 lepidolite and rubellite. The former remarkable for the great 

 quantity and purity in which it occurs, and the latter for its ex- 

 quisitely radiated crystal aggregates. The i-uby-tinted tourma- 

 line imbedded in the pale lilac-colored mica presents a picture of 

 beauty rarely equaled in the mineral kingdom. Before giving 

 a detailed description of the occurrence of these minerals, a few 

 words on the general geology of the district may not be out of 

 place. 



San Diego, the southern county of the State, is dominated 

 by one main system of mountains known as the Peninsula 

 Range. This consists of a confused mass of mountains and val- 

 leys rising gradually from the coast to the summit, forty miles 

 inland, from which the descent is quite abrupt to the Colorado 

 Desert. The average height of the watershed is about four thou- 

 sand feet, but toward the northern boundary of the county, 

 Mount San Jacinto reaches an altitude of about ten thousand 

 feet. This Peninsula Range consists chiefly of granite which of- 

 ten takes on a dioritic facies. Dark basic diorite and rocks of 

 the norite type occur as intrusions of considerable magnitude. 

 Quartzite, mica schist, and thin bedded gneisses form long, nar-
