ON SCIENCE-LECTURES AND ORGANIZATION. 515 



In the mean time I enclose a memorandum showing how our observations 

 in magnetism and meteorology now stand. 



Since the beginning of 1872 we have published the results of meteorological 

 observations at Melbourne, and those of the stations in a more condensed 

 form ; copies of this monthly Record are, I believe, sent to you every month, 

 but I post another coi)y now in case I am mistaken. In this pamphlet you 

 will see we give the results of our monthly observations for the absolute 

 force of Terrestrial Magnetism. 



The question, how to make all these available to such men of science as may 

 wish to make use of them, is not easy to answer. Pentagraph or Photo copies 

 of all the graphic records could be furnished; and MS. copies of such un- 

 published other observations could also be made to be deposited in any con- 

 venient place that the Committee of the B. A. may decide upon. This, or 

 any other plan, I should be glad to adopt in order to render our work of use 

 and available. I shall be glad to hear what the Subcommittee recommend 

 or decide upon, and I shall do my best to faU in with its views. 



Yours faithfully,

Magnetic Observations. 



Between 1863 and the end of 18G7 occasional absolute determinations 

 were made with Lament's instruments, which are unpublished ; from De- 

 cember 1867 regular monthly absolute determinations were made with the 

 Kew instruments, which are not published to the end of 1871 ; also the 

 Magnetograph Curves are complete from December 1867, of which no results 

 are published. 



Meteorological Observations. 



Barograph Curves complete from August 1, 1869 — not published. Ther- 

 mograph Curves complete from January 21, 1870 — not published. Meteoro- 

 logical Observations for Melbourne and country stations, impublished from 

 January 1, 1863, to December 31, 1871. From January 1, 1872, results of 

 Meteorological and absolute Magnetical Observations have been published 

 monthly.

 Deae Sir, 

 I am in receipt of your letter 6th of March, enclosing a resolution of the 

 Subcommittee of the British Association. 



I shall be glad to assist you in any waj^ I can. 



(1) Our magnetic observations are few; none were taken before Mr. 

 Smalley's arrival in 1864, and, with the exception of a few determinations 

 of variation and observations of dip at different parts of the colony, the rest 

 were found at his death to be wanting in some essentials for their reduction. 

 At the present time the press of work, astronomical and meteorological 

 (I have now more than forty stations), renders it impossible to do more than 

 take the variation, but 1 hope in a few weeks to have a Declination Magne- 

 tograph at work.
