ADDRESS. 



The increased interest, manifested in all brandies of Science, has made it appear desirable, 

 that a Periodical should be published sufHciently reasonable in price, so as to place the work 

 within the reach of all who desire philosophical knowledge. Mr. Lowe has consented to 

 conduct a Popular Monthly ^lagazine bearing the above title. 



Our knowledge of Meteorology has advanced so rapidly within the last few years, that 

 it seems absolutely requisite that this science should be properly represented in a monthly 

 Periodical. 



The connection between the health of man and the changes of the weather, opens to us 

 another field for investigation; disease and mortality will therefore be compared, each 

 month, with the weather-changes ; together with the times of coming into leaf, of flower- 

 ing, and ripening of fruit, of various plants ; the arrival and departure of migratory birds, 

 and various other facts in connection with a calendar of Nature. 



The different subjects in Astronomy will from time to time be introduced ; indeed, tlic 

 discoveries and iuiportant features newly brought to light in every branch of Science will 

 constantly occupy a portion of the pages of this Periodical, and this will necessarily include 

 the proceedings of the Learned Societies. 



A map of the weather, in conjunction with different diseases, will be given every month; 

 with other illustrations of any remarkable or interesting phenomenon. 



The expenses of the work, published at so reasonable a price, can only be met by a very 

 large circulation; it is therefore confidently hoped, that all who are anxious for the advance- 

 ment of Science, will give it their support.

ADDRESS. 



The utility of an illustrated work upon the Feras cultivated in Great Britain, both I'ritisTt 

 and Exotic, cannot be doubted ; yet, such a History, embracing the whole of the known 

 ■species indigenous or inti-oduccd mto England, is a great undertaking ; and there is not al
