TO OUR READERS AND CORRESPONDENTS. 



The pages of this Journal are impartially open to all communications 

 upon the subjects of Science, Scientific Literature, and the Arts ; and it 

 is requested that they may be forwarded to the Editor, at least one 

 month previous to the period of the publication of each Number. 



We shall be happy to receive papers from Provincial Scientific and 

 Literary Societies, and to publish them either on the part of the Society, 

 or of their respective authors. 



Papers which are too long for insertion, as is the case with many 

 which we receive, or which are deemed unfit for this publication, will be 

 immediately retumed to the source whence we receive them, with our 

 reasons for their return. 



Three letters have reached us upon the subject of the Grand Junction 

 Water Company's supplies. We quite agree with the writers as to the 

 state of the liquid furnished, but have had no time to inquu-e into its 

 cause. It certainly has at times " a most antient and fish-Hke smell." — 

 We shall notice the Dolphin in our next Number, recommending it, 

 in the mean time, to the serious consideration of those whom it 

 concerns. 



Mr. Heineken's paper, from Madeu-a, reached us too late for inser- 

 tion, but an abstract of its contents will be given in our next Number. 

 We cannot take upon ourselves to transfer it to any other Journal 

 without the Author's special directions upon the subject. 



Philochemicus has come to hand, but we cannot persuade our- 

 . selves to admit a mere chain of argument as evidence against experi- 

 ment. We allow the insufficiency of the views which he combats ; but 

 nevertheless the experiments upon which they are founded are stated — 

 if Philochemicus will repeat these, and show that the author is mistaken 

 in his conclusions, we shall immediately insert liis communication with 

 thanks.
