514 REPORT — 1873. 



(c) Barographic curves since February 1872. 



(d) An extensivp collection of daily meteorological observations taken on 

 board ships in the Indian Ocean for a period of twenty-five years. Since 1853 

 these observations have been tabulated in chronological order. They aiford in- 

 formation respecting the atmospheric pressure and temperature, the direction 

 and force of the wind, the state of the weather and sea &c., and amount to about 

 250,676 of twenty-four hours each. 



(e) A separate collection of the details of the hurricanes, storms, and gales 

 which have taken place in the Indian Ocean since 1847. 



(/) A large number of daUy synoptic weather-charts of the Indian 

 Ocean for different periods since 1853, and charts showing the tracks of 

 hurricanes. 



(g) Observations of the absolute values and daily variations of the magnetic 

 elements since February 1872. 



(h) Sun-spot observations taken three or four times a week since 1869. 



All these observations are valuable, but, considering the length of time 

 and the locality, I think the meteorological observations are the most valu- 

 able. 



(2) I have little doubt that the Observatory and the Meteorological Society 

 would consent to open up the observations to men of science, on condition of 

 their paying the esiiense of copying, and that they would, as far as possible, 

 give copies gratis. The best and cheapest way in the end, however, would pro- 

 bably be to publish the observations in extenso, and to distribute copies of 

 them. The Meteorological Society will do all in its power to accomplish this 

 object.

 My dear Sie, 

 "With respect to your letter requesting copies of magnetical observations 

 which have been made here. Soon after I came here I hunted these records 

 up and completed their reductions, but the observations have not received my 

 final examination. I hope, however, to get them printed this year, when 

 copies shall be at once forwarded to you. I am sorry, however, to say that the 

 observations do not appear of great value. However, such as they are, you 

 will soon have the results. 



Believe me, 



Yours very truly, 

 Professor B. Stewart. E. J. Stone.

 My dear Sir, 

 I received your note and enclosure (resolution of the Observational Sub- 

 committee of the B.A.) by last mail, and I am very glad to find a step has 

 been taken in this most important direction. We shall be only too glad to 

 make any arrangements we can to meet the end in view. I suppose, of 

 course, there wUl be some general scheme adopted in which we can join.
