A LETTER to the Harvard College Observa- 

 tory from the Eev. Joel H. Metealf, of Taun- 

 ton, Mass., announces that he photographed 

 the planet OcUo (475) on 1907, Jan. ll^ 

 15" 30".5 G. M. T. in 



E.A. 7" 32°> 17».8 (1855). 

 Dee. +48° 22' 58". (1855). 

 Note: This object is of interest since its 

 orbit has a greater eccentricity than that of 

 any other known asteroid. A year or two ago 

 it was in danger of being lost. It is now very 

 faint as its computed magnitude at opposition 

 on January 12, 1907, was 14.2. See Harvard 

 Circulars 63, 101 and 103. [E. C. P.] 



The heirs of Dr. J. Brettauer, of Trieste, 

 have presented to the University of Vienna 

 his collection of medical medals. They gave 

 with it a small endowment for the mainten- 

 ance and enlargement of the collection. 



The secretaries of the American Philosoph- 

 ical Society announce that the general meet- 

 ing of 1907 will be held on April 17, 18 and 

 19, beginning at 2 p.m. on Wednesday, April 

 17. Members desiring to present papers, 

 either for themselves or others, are requested 

 to send to the secretaries, at as early a date 

 as practicable and not later than March 20, 

 1907, the titles of these papers, so that they 

 may be announced on the program which will 

 be issued immediately thereafter, and which 

 will give in detail the arrangements for the 

 meeting. Papers in any department of sci- 

 ence come within the scope of the society, 

 which, as its name indicates, embraces the 

 whole field of useful knowledge. The publi- 

 cation committee, under the rules of the so- 

 ciety, will arrange for the immediate publica- 

 tion of the papers presented in the Proceed- 

 ings or the Transactions, as may be desig- 

 nated. 



The Pennsylvania Farmers' Congress has 

 passed the following resolution : 



Whebeas, we the members of the Pennsylvania 

 Farmers' Congress in our annual session at The 

 Pennsylvania State College, realizing not only the 

 great work now heing done by the School of 

 Agriculture and the Experiment Station, but also 

 realizing that the demands upon these institu- 

 tions in the near future will be greatly enlarged 

 if Pennsylvania is to assume and maintain the 



position that naturally belongs to her agricul- 

 turally among her sister states. 



Therefore, be it resolved that we urge upon our 

 representatives in the Pennsylvania Legislature 

 the most careful consideration of, and the most 

 generous response to, the needs of The Pennsyl- 

 vania State College for the maintenance of these 

 institutions for the coming two years. 



The Royal Swedish Academy of Sciences 

 will publish early in the present year the first 

 three volumes of Swedenborg's scientific 

 works, edited from the original MSS. in the 

 Library of the Royal Academy in Stockholm, 

 by a committee of the Royal Academy, as- 

 sisted by Alfred H. Stroh, of the Swedenborg 

 Scientific Association of America, The first 

 three volumes will be: Vol. I. Geology — In- 

 troduction by A. G. Nathorst. Vol. II. 

 Chemistry, Physics, Mechanics— Introduction 

 by Svante Arrhenius. Vol. III. Cosmology — 

 Introduction by Svante Arrhenius. These 

 volumes will be followed by others on anatomy 

 with introductions by Gustav Retzius. The 

 volumes are in Latin with the introduction in 

 English. They are the result of the most 

 notable efforts to put in the hands of the sci- 

 entific world the earlier writings of Sweden- 

 borg. A new and revised edition of his Prin- 

 cipia Berum Naturalium in English, long out 

 of print, is now going through the press in 

 England, under the auspices of the Sweden- 

 borg Society of London. 



The report of the U. S. Geological Survey 

 on the production of gold and silver during 

 1905, compiled by Mr. Waldemar Lindgren, 

 has now been published. The figures show- 

 ing the production of gold and silver, in 

 approximate distribution by states and terri- 

 tories, are the result of conference and ad- 

 justment between the Geological Survey and 

 the Bureau of the Mint, and are accepted as 

 final by the two bureaus. The total produc- 

 tion of gold was 4,265,742 fine ounces valued 

 at $88,180,700; the total production of silver 

 was 56,101,600 fine ounces valued at $34,221,- 

 976, making an entire total value of $122,- 

 402,676. The production of gold in the 

 United States for 1905 represents an increase 

 of $7,716,000 in value over the production 

 of 1904. The rapid advance in gold produc-
