_Arago on the Weather_ (Vol. vii., p. 40.).--ELSNO will find extracts from
Arago's papers in the _Pictorial Almanack_, 1847, p. 30., and in the _Civil
Engineer and Architects' Journal_, which volume I cannot say, but I think
that for 1847. Also in the _Monthly Chronicle_, vol. i. p. 60., and vol.
ii. p. 209.; the annals of the _Bureau des Longitudes_ for 1834 and the
_Annuaire_ for 1833.
