in the rear." This conclusion, Mr. Clayton 

 believes, "will probably find general accept- 

 ance as representing the conditions up to 

 6 Ions, everywhere in temperate latitudes." 

 In answer to a criticism made by Hann (Met. 

 Zeitschr., Nov., 1905, 491) to the effect that 

 Mr. Clayton had determined the central areas 

 of cyclone and anticyclone from the time of 

 high and low pressure at Blue Hill, and not 

 from the weather maps, our author points out 

 that the weather maps were used. We our- 

 selves carelessly omitted to point out that Dr. 

 Hann was mistaken in his objection, on the 

 occasion of our mention of this matter in 

 these notes some months ago, 



CLIMATOLOGIOAL ATLAS OF INDIA. 



One of the most attractive, as well as one 

 of the most important publications in clima- 

 tology ever issued is the new ' Climatological 

 Atlas of India,' prepared by Sir John Eliot, 

 lately meteorological reporter to the govern- 

 ment of India, and published by Bartholomew, 

 of Edinburgh. This atlas contains one hun- 

 dred and twenty colored maps, showing with 

 great detail and in well-selected, harmonious 

 colors, the distribution of the climatic ele- 

 ments over the Indian empire. We learn 

 from the preface that a handbook of the 

 weather and climates of India is in prepara- 

 tion and will be a companion volume to the 

 atlas. India has for many years been well 

 known for its admirable meteorological service 

 and for its long series of valuable meteorolog- 

 ical publications. Sir John Eliot has now 

 fittingly ended his term of service as head of 

 that organization by preparing this magnifi- 

 cent volume which will always stand as a 

 monument to his work. 



MONTHLY WEATHER REVIEW. 



The last number of the Monthly Weather 

 Review (No. 6, 1906) contains an illustrated 

 paper by Professor J. E. Church, Jr., of the 

 University of Nevada, on the new ' Mount 

 Rose Weather Observatory,' in Nevada ; a plea 

 for the ' Use of the Lantern in Teaching 

 Meteorology,' by Professor J. P. Goode, of the 

 University of Chicago; a further instalment 

 of his ' Studies on the Thermodynamics of 



the Atmosphere,' by Professor F. H. Bigelow; 

 a description of a waterspout near Tarrytown, 

 N. Y., July 16, 1904, illustrated by six half- 

 tones ; an account of * The Tornado of June 

 6, 1906, near La Crosse, Wis.,' by G. A. Ober- 

 holzer, and of ' The Tornado of April 12, 1906, 

 at Stafford, Kansas,' by W. E. Seright; and 

 several short papers on ' The Structure of 

 Hailstones.'

Professor W. I. Milham has published a 

 ' Syllabus of a Course on Meteorology,' given 

 by him in Williams College. The course is a 

 three-hour elective for juniors and seniors, 

 and is much more thorough than most of the 

 courses at present being given in American 

 colleges. Practical work in making observa- 

 tions, in generalizing frora meteorological 

 data and in making forecasts, is required as 

 part of the course.

The Annual Report of the Transvaal Me- 

 teorological Department for the year ending 

 June 30, 1905, contains several charts showing 

 the distribution of the various meteorological 

 elements; also half-tones of lightning views 

 taken at Vereeniging in 1904—5.

REGENT IMPORTANT ANTI-MALARIA 

 WORK. 



The latest reports on the measures taken 

 to abolish malaria from Klang and Port Swet- 

 tenham in Selangor, Federated Malay States, 

 indicate the most admirable results. These 

 measures were undertaken first in 1901 and 

 1902, and have been xeported upon from time 

 to time in the Journal of Tropical Medicine. 

 The expenditure undertaken by the govern- 

 ment with a view to improving the health of 

 the inhabitants of these towns has been fully 

 justified by the results which promise to be 

 of permanent value. The total expenditure 

 for the town of Klang, down to the end of 

 1905 was £3,100, and the annual permanent 

 expenditure is about £60 for clearing earth
