some time between June 16 and July 24. 

 Connected with it there will be a scientific and 

 medical exposition divided into sections as 

 follows: I. Natural Science and Medicine, 

 subdivided into the following groups : (a) 

 scientific and medical; (&) balneological; (c) 

 pharmaceutical; (d) industrial chemistry; (e) 

 medical instnmients and apparatus. II. Hy- 

 giene, subdivided into groups as follows: (a) 

 hygiene of nutrition; (b) personal hygiene; 

 (c) hospital administration; (d) training of 

 youth; (e) hygiene of factories and work- 

 shops; (f) hygiene of the dwelling; (g) hy- 

 giene of clothes; (h) infectious diseases and 

 their prevention; (i) hygiene of childhood; 

 (j) public health. Foreign institutes and 

 firms may take part in the scientific section 

 of the exposition, but may only show such 

 objects as will not interfere with Polish indus- 

 tries. Communications should be addressed 

 to the director of the exposition. Dr. Kalikst 

 Kryzanowski, Lemberg. 



The bill to prohibit vivisection in Pennsyl- 

 vania has been dropped from the calendar in 

 the legislature. This action followed an ad- 

 dress in opposition to the measure made to 

 fifty members of the house by Dr. S. Weir 

 Mitchell of Philadelphia. 



Under the direction of the College of Agri- 

 culture of Ohio State University a special 

 train was recently run through several parts 

 of the state bearing certain exhibits of interest 

 to agriculturists. Brief addresses were made 

 at the various towns passed through by in- 

 structors from the university. 



That part of the fuel testing equipment 

 being operated by the Geological Survey 

 which relates to the investigation of fuels 

 under the boilers and the gas producers, and 

 the briquetting investigations, is now being 

 transferred to Norfolk, Va., where during the 

 Jamestown Exposition these will be used in 

 testing coals, lignites and peats of the At- 

 lantic and Gulf seaboards; and during this 

 time will be tested specially the fuels available 

 for the use of the navy, testing the briqueted 

 coals as compared with the run-of-mine coals 

 from the same mines. The other part of the 

 fuel testing plant equipment which relates to 



the coking of coals, including the coal wash- 

 ing investigations, is now being transferred 

 to Denver, Colo., where investigations will be 

 conducted during the remainder of the present 

 year to determine the coking qualities of the 

 different coals in the Rocky Mountain and 

 other western states. 



Dr. Willis L. Moore, chief of the Weather 

 Bureau, writes in his annual report for the 

 year ending June 30, 1906, in regard to the 

 Mount Weather Eesearch Observatory as fol- 

 lows : " The meteorological work of a first- 

 order station has been maintained throughout 

 the year, and telegraphic reports were trans- 

 mitted to the Central Ofiice in Washington 

 daily at 8 a.m. and 8 p.m. Work on the phys- 

 ical laboratory was resumed in July and satis- 

 factory progress was made during the summer 

 and fall of 1905. The building will probably 

 be completed early in 1907. In the prepara- 

 tion for kite and balloon work a number of 

 important instruments have been installed and 

 made ready for systematic work. Among 

 these may be mentioned: (1) The electrolyzer, 

 for the manufacture of the hydrogen gas em- 

 ployed in the kite balloon and the small rubber 

 balloons; (2) the apparatus for the manufac- 

 ture of liquid air, employed in testing ther- 

 mometers at very low temperatures; (3) the 

 apparatus used in testing the barometers, 

 thermometers and meteorographs employed in 

 connection with the kites and balloons. A 

 medium-sized power kite-reel was installed in 

 the revolving kite-house early in the year, and 

 experimental kite-flying was begun in Septem- 

 ber of 1905. During the year the stock of 

 meteorographs, of kites and of kite wire was 

 materially increased; the instrumental equip- 

 ment now includes eight different styles of 

 kite-balloon meteorographs, comprising Eng- 

 lish, German and French designs, in addition 

 to the Marvin type heretofore used in the kite 

 work of the bureau, and the new Fergusson 

 pattern used at the Blue Hill Observatory. 

 In April, 1906, systematic cooperation was 

 begun in connection with the work of the 

 International Committee for Scientific Bal- 

 looning by flying kites on prearranged term 

 days, and this work is being regularly main-
