 The following are worth attention : — 



Port Darwin 42-44 inches to 81*72 inches. 



Alice Springs 5*39 ,, 27*21 „ 



Parallina 1*71 „ 20-41 „ 



Adelaide 13*43 „ 30*87 „ 



At Leon, Estado de Guanajuato, Mexico, the range is from 1239> 

 inches to 35-79 inches." 



At Algiers the range is from 17 inches to 51*45 inches.! 



At Cordoba, Argentine, from 19 inches to nearly 40 inches.;]; 



In India we have Calcutta, with an annual average of about 65 

 inches, and a range from 38*5 to 98*5 ; Cawnpore, with an average 

 of 32*3 inches, and a range from 7*1 to 60*7 ; Kurrachee, with an 

 average of 7*6 inches, falling sometimes below half an inch, and 

 rising sometimes to 28 inches; Bombay (Colaba), with an annual 

 average of 74 inches, and a range of 79 inches from 359 to 1149.§ 



At Durban the range is from 27*24 inches to 71*27 inches ; at, 

 Port Elizabeth from 10*41 to 33*59 ; at Cape Town from 17 to 41. 



Therefore, while the range at stations near the coast of South 

 Africa is not materially different from that of other coasts, the range 

 at Kimberley is relatively less than that of the inland stations of 

 Australia and India, and greater than those of the interior of South 

 America. 



Table 14 has been designed to show the total rain of Tables 1-12; 

 in twenty-four equal parts of a year of fifteen days each. To obtain 

 this the total fall of February 29th has been increased in the ratio 

 5 : 26, there having been five leap-years in the period under review. 

 The twenty-four quantities so obtained may be expressed in inches, 

 by the formula : — 



E - 483*024 + 18-012 sin (»15° + 70°) 



+ 4-428 sin (7*30° + 340°-8) 

 + 9*764 sin (?i45° + 339°*8) 

 + 2-028 sin {n60° + 211°-4) 

 + 



The relative magnitudes of the third and fourth terms of this formula, 

 are worth notice. 



Table 15 epitomises Tables 1-12, giving for each month the number
