republic, and the botanical calendar for about fifty families 

 of flowers in the valley of Mexico. 



Dr. B. A. Gould has published Vol. I. of the "Annals of 

 the Meteorological Office of the Argentine Republic." He 

 gives a large amount of data for Buenos Ayres a wholly 

 new meteorological field and has subjected it to an elabo- 

 rate study, with many curious results. 



The Council of the London Meteorological Society have ar- 

 ranged a course of six lectures on meteorology, to be given 

 by eminent specialists. Lectures will be open to the public, 

 and tickets of admission can be obtained of the Society. 

 The first lecture, by Mr. Mann, on the Physical Properties 

 of the Atmosphere, we are sorry to see, promulgates Tyn- 

 dall's opacity of aqueous vapor, and the radiation -of- heat 

 theory of clouds and rain errors to which, we presume, the 

 Royal Society Meteorological Council will hardly lend their 

 approbation. Probably no more effective method could be 

 devised for disseminating a knowledge of meteorology in 

 America, since such lectures are sure to be supplemented 

 by their still wider distribution through the newspapers. 



Among the subjects of investigation to be assisted from 

 the orovernment fund of 4000 for the advancement of science, 

 we note that 50 have been voted to the Scottish Meteoro- 

 logical Society for aid in carrying on a simultaneous series 

 of anemometrical observations at different heights, and in 

 sheltered and unsheltered situations ; also 200 to Dr. J. P. 

 Joule for an exhaustive inquiry into the change which takes 

 place in the freezing- and boiling-points of mercurial ther- 

 mometers by long exposure to those temperatures. 



The London Meteorological Office has begun the publica- 

 tion of a Weekly Bulletin. 



The Leipsic Observatory, under Bruhns, now publishes 

 w r eather forecasts for the agriculturists. 



The Annalen der Ilydrographie und Maritimen Meteor o- 

 logie, published monthly by the Admiralty, at Berlin, con- 

 tains regularly a few pages, in double columns, comparing, 

 month by month, the weather of America and Europe. Full 

 abstracts are given of the ships' logs that carry verified in- 

 struments, and that report to the Deutsche Seewarte. There 

 are also a tabular review of the weather at the German sea- 

 coast stations, and very numerous excellent special meteoro-
