METEOROLOGY — WATER. 713 



ject compiled by II. A. Hunt, commouwealtli meteorologist of Australia. The 

 article also gives the history of Australian meteorology, describes the organiza- 

 tion and publications of the meteorological service of the commonwealth, and 

 discusses the influences which afl'ect Australian climate. 



Hail protection, A. Trollkr {Nature [Paris], 37 {1909), No. 1890, pj). 115, 

 176, fig. 1). — This article briefly describes experiments which have been under- 

 taken by Negrier and by de Beauchamp (E. S. R., 22, p. 118), with a view to 

 warding off hail storms by means of high towers carrying conductors which draw 

 off the atmospheric electricity. 



Hail protection in Beaujolais, J. Violle {Compt. Rend. Acad. Sci. [Paris], 

 150 {1910), No. 18, pp. 1087-1090; Bui. Soc. Nat. Agr. France, 70 {1910), No. 6, 

 pp. J,70-'t7'6; aJ)s. in Rev. ScL [Paris], J,8 {1910), I, No. 20, p. 635).— Statistics 

 are presented indicating a much smaller loss from hall in the Province of 

 Beaujolais during the 6 years 1901 to 1906, in which cannonading was practiced 

 as a protective measure, than during the preceding 10 years, when no attempts 

 at protection were made. The negative results obtained in the government trials 

 at Castel-Franco, near Venice, are referred to, but the author maintains that 

 the conditions there were such that the results do not have general application. 



The water supply of Indiana, H. E. Barnard and J. H. Brewster (Ann. Rpt. 

 Bd. Health Ind., 27 {1908), pp. 3-'io-373, dgins. 2).— This article reports and dis- 

 cusses the results of analyses of 918 samples of water from different parts of 

 Indiana. 



Of the 288 samples of deep well waters examined, 220 were of good quality, 47 

 were so polluted as to be classed as bad, and 21 were of doubtful quality. Of 

 the 419 samples of shallow well water examined, 166 were of good quality, 209 

 imqualifiedly bad, and 44 of doubtful quality. Of the stream supplies examined, 

 25 were good, 7 bad, and 1 doubtful. Of the 30 pond or lake supplies examined, 

 24 were of good quality, 5 were bad, and 7 of doubtful quality. Of the 47 spring 

 waters analyzed, 37 were of good quality, 1 was grossly polluted, and 7 were 

 doubtful. Of the 27 samples of cistern water 14 were of good quality and 13 were 

 polluted. 



Of the 190 analyses of water from public supplies. 111 were from deep wells, S 

 from shallow wells, 33 from streams, 31 from ponds or lakes, and 7 from springs. 

 " Of the deep well supplies, 104 were of good quality, 2 were bad, and 5 were 

 doubtful. The deep well waters used as public supplies are for the most part of 

 excellent quality from a sanitary standpoint. ... Of the 33 river supplies, 22 

 were of good quality, 7 were bad, and 1 was doubtful. . . . 



"Of the private supplies, 177 were deep welTs, 411 shallow wells. 5 ponds. 40 

 springs, and 27 cisterns. One hundred and sixteen of the deep well waters were 

 of good quality, 45 were bad, and 10 doubtful. But 159 of the 411 shallow well 

 waters were potable, 209 were unequivocally bad, and 43 were of doubtful 

 quality. The shallow well is never a satisfactory source of water supply, and 

 except in rare instances, when it is located far distant from any possible source 

 of ix>llution, should never be used until a thorough analysis has shown it to be 

 uncontnminated by human filth. The continued use of shallow wells by city and 

 town dwellers is a reproach upon our intelligence." 



The combined action of nitrous gas and oxyg'en on water, Foerster and 

 Kocii (Moiiit. aS'c(., .'/. ser., 2', (1910), /, .Yo. 821, i>i>. 30(;-333. figs. 5).— This is a 

 detailed technical study of this subject. 



Sterilization of water by means of quartz lamps, M. von Recklinghausen 

 {Jour. Roy. Sanit. Inst., 31 (1910). No. 5. pp. 172-175. fig. /).— The development 

 of this process is explained, and an apparatus capable of effectively sterilizing 

 3,500 cu. ft. of water per hour is described.
