Journal, but it appears that in addition tlie 

 steamsliip, under Commander J. P. Moser, has 

 secured important data for charts and maps. 



It is stated in Nature that Mr. J. S. Budgett, 

 of Trinity College, Cambridge, who, it will be 

 remembered, accompanied Mr. Graham Kerr 

 on his journey in search of Lepidosiren, and 

 who last year spent several months investigat- 

 ing the zoology of the Gambia region, has just 

 returned to England from a second expedition 

 to that river. Mr. Budgett' s main object was 

 to obtain material for studying the development 

 of the Crossopterygian fish Polypterus. In his 

 first expedition he obtained eggs and larvse 

 which were said to be those of this fish, but 

 which, as it turned out, belonged apparently to 

 a Teleost. Mr. Budgett has in his recent ex- 

 pedition failed to obtain the Polypterus ma- 

 terial, but he is to a certain extent compensated 

 for this by having obtained a mass of embryo- 

 logical material which appears to be of great 

 interest. Amongst this is a practically com- 

 plete series of eggs and larvse of the Dipnoan 

 Protopterus whose developmental history had 

 hitherto remained quite unknown. The de- 

 velopmental stages of all three surviving mem- 

 bers of the important group Dipnoi — Ceratodus, 

 Lepidosiren and Protopterus, belonging to 

 Queensland, South America and Africa re- 

 spectively — owe their discovery and first ob- 

 servation to workers of the Cambridge school 

 of zoology. 



In connection with the United States Geolog- 

 ical Survey, the Yale School of Forestry is to 

 undertake on an extensive scale the measure- 

 ment of the flow of some of the larger streams 

 of Connecticut. The first station has already 

 been established at Merwinsville on the Housa- 

 tonic River. 



Peopessoe David P. Todd, of Amherst Col- 

 lege, in a lecture in Brooklyn, on November 1st, 

 exhibited biograph pictures of the solar corona 

 taken at the recent eclipse. About 300 pic- 

 tures were taken in a period of one minute and 

 twenty seconds, and these were reproduced on 

 the screen at the same rate. 



The survey of the crystalline rocks of the 

 Adirondack region and of the Highlands area 

 of southeastern New York has recently made 



rapid progress, and the results are now avail- 

 able for the new edition of the large geologic 

 map of the State, which will go to press befoi-e 

 the close of this year. Important work has 

 been done in quaternary geology by Dr. J. B. 

 Woodworth, of Harvard University, and Pro- 

 fessor H. L. Fairchild, of the University of 

 Eochester. 



The National Geographic Society has de- 

 cided to disoontinuet he technical course of lec- 

 tures during November and December and to 

 omit the Lenten course this season. The course 

 of popular lectures will be opened Friday, No- 

 vember 9, 1900, by Mr. M. H. Saville, of the 

 American Museum of Natural History, New 

 York, the subject being ' The Ancient City of 

 Mitla, Mexico.' The second lecture will be 

 given by General A. W. Greely, Chief Signal 

 Officer, U. S. A., on Friday evening, November 

 23, 1900. General Greely's subject will be ' A 

 Trip through Alaska.' 



The course of free public lectures for the 

 winter season at the University of Pennsyl- 

 vania has been announced. The lectures will 

 be delivered in the College Chapel on Tuesday 

 afternoons at four o'clock. Those in science 

 are as follows : March 19, 1901, Lightner 

 Witmer, 'Mind and Body'; March 26, 1901, 

 John M. Macfarlane, ' The Adaptation of Plants 

 to their Surroundings'; April 2, 1901, Arthur 

 W. Goodspeed, 'Color' ; April 9, 1901, Edwin 

 G. Conklin, ' Some Recent Advances in our 

 Knowledge of Life' ; April 16, 1901, Alexan- 

 der C. Abbott, ' The Management of Polluted 

 Water Supplies and its Influences upon Public 

 Health.' 



AccoEDiNG to the daily papers ofiicers of the 

 German Government have arranged with the 

 Principal of the Tuskegee Normal and Indus- 

 trial Institute to send three graduates of that 

 institution to the German colony on the west 

 coast of Africa for the purpose of introduc- 

 ing the raising of cotton among the na- 

 tives. Two of the graduates are from the 

 agricultural department and one from the me- 

 chanical department. The latter will construct 

 gin-houses, etc. Mr. J. N. Calloway, one of 

 the instructors of Tuskegee, accompanies the 

 party to assist in the inauguration of the work.
