into the dispensations of Providence, and the improbability of this 

 Earth being the only one where creatures exist which partake of the 

 Divine nature, and his treatment of cognate subjects, form as solid 

 arguments in favour of the habitability of other worlds as the phy- 

 sical data that he has collected to prove his point. 



He considers the Worlds around us to be stations in Heaven ; the 

 regions of our future immortality, if we may be permitted to use the 

 expression. They constitute the Heavenly home of many mansions, 

 and to them he believes his ancestors to have passed ; " Nous recon- 

 naissons," he says,* "celui que nous habiterons un jour. Toute 

 croyance pour etre vrai doit s'accorder avec les faits de la nature. 

 Le spectacle du monde nous enseigne que l'immortalite de demain est 

 celle d'aujourd'hui et celle d'hier ; que l'eternite future n'est autre que 

 l'eternite presente ; c'est la notre foi, notre paradis ; c'est l'infini des 

 mondes." 



Irrespective of the value of this book, as regards its avowed 

 aim of proving the habitability of the other spheres, it will be 

 found useful for the amount of tabulated information which it con- 

 tains regarding the planets; and the illustrations, which are well 

 executed, will serve along with the text to convey to a young student 

 a very excellent idea of the Solar system. 



The language is clear and simple, and in many places it rises to a 

 standard suited to the sublime theme of which the volume treats. 

 We shall be glad to welcome a translation of the work in our own 

 language. 



THE CULTIVATION OF QUININE.! 



The cultivation of Quinine in Java and British India has been treated of 

 lately by Dr. J. E. De Vrij. The Quinine-yielding trees grow at various 

 heights above the level of the sea in the primitive forests of the con- 

 tiguous republics of Venezuela, New Grenada, the Ecuador, Peru, and 

 Bolivia. The medicinal properties of the trees have been known 

 from time immemorial to the natives of those countries, but it was not 

 until 1632, that the curative powers of Quinine were known in Em-ope. 

 The cure effected by the remedy in the Countess de Chinchon, wife of 

 the Viceroy of Peru, brought it into greater notice. The trees were 

 included by Linnasus, in the Genus Cinchona, or, as Dr. De Vrij 

 and others call it, Chinchona. Various species of Cinchona yield 

 the febrifugal alkaloids, Quinine, Cinchonine (Chinchonine), Quini- 

 dine, and Cinchonidine. Of these Quinine is the most powerful, and 

 hence the most valued. The species which yields it in largest quan- 

 tity, is Cinchona Calisaya. Great apprehensions were entertained 

 recently that the trees in South America would ultimately become
