 on these or other points. 



Erom the enclosed " Regulations " you will see that every Light-keeper on 

 being first appointed as a supernumerary has to learn the use of the meteoro- 

 logical instruments, and to obtain a certificate of competency in that and 

 other duties. 



Believe me, 



Very truly yours,

 Dear Sir, 

 Sir Frederick Arrow having placed your note of the 10th instant, with its 

 enclosed resolution of the Science-Organization Committee of the British 

 Association, before the Board, I am directed to assure you of the pleasure it 

 will be to the Elder Brethren to afford any facilities to men of science for the 

 inspection of the Trinity House meteorological records that may be compati- 

 ble with their oificial purpose ; and I am to suggest that if you can make it 

 convenient to attend here about half-past one o'clock on any Tuesday, the 

 Light Committee will be happy to go fully into the matter with you. 



I am, dear Sir, 



Your most humble Servant, 

 (Signed) Robix Allen. 



Dr. J. H. Gladstone, F.B.S.

Observatory, Mauritius, 

 26th June, 1873. 

 Mt dear Stewart, 

 I enclose a copy of my answers to your questions. We are to make a bold 

 attempt to publish all our observations on the spot. The first step is to find 

 out the cost, and the next to raise the funds. The local government will be 

 applied to for a small annual grant. If we get the necessary assistance, there 

 need be no delay, as the greater part of the material is ready, all the meteoro- 

 logical observations having been reduced. 



Yours truly, 



C. Meldrum,
