[N. S. Vol. III. No. 56. 



The London Times states that the President 

 of the Royal Astronomical Society has an- 

 nounced the plans of the permanent eclipse 

 committee in view of the eclipse of the sun 

 occurring on the 9th of August, this year, 

 and that two new instruments to be used in 

 observations have been shown to members 

 of the Society. One of these, the ccBlostat, 

 suggested by M. Lippmann, in the Comptes 

 Bendus, has been made on the advice of Dr. 

 Common, who has contributed the plane mir- 

 ror of the instrument. Its purpose is to 

 deflect the rays of the object into a fixed 

 telescope, instead of having to put the tele- 

 scope itself in motion. The second instru- 

 ment is a modification of the Foucault helio- 

 stat, by Captain Hills; and this, in similar 

 manner, deflects the image rays. It is said 

 that Dr. Common will accompany the expedi- 

 tion to Vadso, and will take photographs, with 

 a long axis mirror or lens, of the lower portion 

 of the corona. The telescopes and the spectro- 

 scopes will be the same as formerly employed, 

 for the sake of continuity. Two steamships 

 will be sent from London to Vadso on the 

 Varanger Fiord, which will afford tourists as 

 well as men of science a convenient opportunity 

 to witness the eclipse.

The Imperial Academy of Sciences of St. 

 Petersburg has elected as honorary members, 

 Hermite, Weierstrass and Pope Leo XIII ; as 

 corresponding members, Darbous, Klein, Fuchs, 

 Jordan, Picard, Poincar6. 



The academicians Sonine and Markov have 

 commenced an edition of the collected works of 

 Pafnooti Lvovich Chebishev, in Russian and 

 French. All papers written in Russian will be 

 translated into French, and vice versa. A 

 translation of the greatest work of Lobachevski, 

 his ' New Elements of Geometry with a Com- 

 plete Theory of Parallels,' is so much desired by 

 men of science that at the Centenary Anniver- 

 sary of the Institute of France Sophus Lie 

 and Darboux addressed to the representative of 

 the Russian Academy of Sciences the request 

 that all the works of Lobachevski be published 

 in French. Without waiting for the effect of 

 this request, negotiations have been set on foot 



looking to the publication in Paris by Gauthier- 

 Villars or A. Hermann, of a French translation 

 furnished from America but edited by Professor 

 A. Vasiliev, the great Russian authority on 

 Lobachevski. 



Vasiliev' s address on Lobachevski has been 

 reproduced in German by Prof. Friedrich Engel, 

 of the University of Leipzig, who acknowledges 

 his indebtedness to Halsted's English transla- 

 tion, reviewed in this journal March 29, 1895. 



K. A. Andreyev, President of the Mathe- 

 matical Society of Charkov, has issued an im- 

 portant monograph on Vasili Grigorevich Im- 

 shenetzki, with a handsome portrait. It in- 

 cludes biography, critical estimate and bibli- 

 ography. George Bruce Halsted.

 The names of the members of the general 

 committee of the Huxley Memorial have now 

 been published. The total number is about 800, 

 of whom about 50 are Americans. We have 

 not learned of any steps having been taken to 

 organize an executive committee in America, 

 and it is not clear whether intending subscrib- 

 ers shovild wait for this or should send their 

 subscriptions to England. Donations may, how- 

 ever, be sent to the Treasurer, Sir J. Lubbock, 

 or the bankers, Messrs. Robarts, Lubbock & 

 Co. (15, Lombard Street, E. C), or to the Hon- 

 orary Secretary, Prof. G. B. Howes (Royal Col- 

 lege of Science, South Kensington, S. W.). 



The French government has voted £400 

 towards the fund for erecting a statue in Paris 

 to the memory of Pasteur ; the fund exceeds 

 the expense, and the surplus is to be used for 

 a bust of Pasteur in the Pasteur Institute. As 

 already stated in this journal, there have also 

 been formed committees at Chartres and Dole 

 for the purpose of erecting statues to the mem- 

 ory of Pasteur in those towns. The French 

 Chamber of Commerce in London would be 

 glad to receive subscriptions for the monument 

 to be erected in Dole, the birthplace of Pasteur. 

 Subscriptions may be sent to the President, M. 

 Marius Duche, Monument House, E. C.
