N. B. The instruments used are all of the first description. The 

 barometer, a standard mountain, by Newman. The register ther- 

 mometers by the same, and compared with a standard by Adie & 

 Son, Edinburgh. The rain gage by Newman, after the one used 

 by the Royal Society, London. Every precaution is used in the 

 placing of the instruments, which a residence in a city will admit of. 



7. Oil of the Tutui or Candle Nut Tree. — From Mr. French of Hon- 

 olulu, through the Rev. John Diell, Seaman's Chaplain, we received in 

 August 1835, a bottle of the oil named above. Mr. French at that time had 

 a mill and press, employed several native hands, and manufactured from 

 one hundred to one hundred and fifty barrels annually. Mr. Diell remarks 

 that " it is found when dried to answer an excellent purpose for paint oil, 

 and that it might be manufactured to any extent, as the trees are found in 

 abundance upon all the islands. The greatest difficulty appears to be in 

 drying it properly — for if it is not boiled very carefully, and to just such 

 a point, it never dries." 



We are not informed whether varnish has been mixed with it, and 

 whether boiled upon litharge, as is common with flax seed oil. 



8. Aerolites. — An account has been received from Brazil, of the ap- 

 pearance of a meteor of extraordinary brightness, and as large as the bal- 

 loons used by aeronauts. It was seen for more than sixty leagues in the
