Ed. New Phil Journ. 1842 p. 134. on Dust in Atlantic

[1846. An account of the fine dust which often falls on vessels in the Atlantic ocean: "Edinburgh New Phil. Journal, vol. xxxii. p. 134.3 The account is taken from Berghaus' Almanack of the dust which fell on the Princess Louise on Jan. 14th and 15th, 1839, between (lat. 24° 20' N., long. 26° 42' W.) and (lat. 23° 05' N., and long. 28° 18' W.): and again in 1840 from the 6th to the 9th of May, whilst between (lat. 10° 29' N., long. 32° 19' W.) and (lat. 16° 44' N., long. 36° 37' W.). During the voyage of a vessel of the same name, in which Dr. Meyen was a passenger (Reise um Erde, Th. i. s. 54)1 on the 27th of October 1830, the sails were observed to be stained by a powder, which Dr. Meyen considered to be a minute Cryptogamic plant: the date would lead me to believe that in this case the phænomenon was different from that of the dust described in this paper."]
