 By Michael Fakaday, Esq. F.R.S.SfC* 



To the Editors of the Philosophical Magazine and Atmals. 

 Gentlemen, 

 TF not inconsistent with the object of your Journal, may I 

 ^ beg your insertion ol' the following erroi's and corrections 

 which have been pointed out to me by Captain Kater. They 

 belong to a work of mine, entitled " Chemical Manipulation," 

 which being intended for instruction ought not to contain such 

 errors uncorrected. Your insertion of the corrections will 

 tend greatly to prevent any harm arising from the errors, and 

 will much oblige, (Gentlemen, 



Your very obedient servant.

Chemical Manipulation; being Instrtictions to Students in Chemistry, 

 on the Methods <f performing Experiments o/^ Demonstration or 

 of Research, with Accuracy and Success. By Michael Fakaday, 

 'F.R.S. F.G.S. Sf-c. Si-c. 



WHILE treatises on Chemistry have been niultipjyiiijj with ra- 

 pidity, and while every form which ingenuity could devise, 

 has been given to the facts and theories of tlic science, there did 

 not, as far as we know, exist, until the appearance of the present 

 volume, any work expressly on luanipulation, and we need, there- 

 fore, hardly remark, that directions given with plainness and accu- 

 racy and without the fear of appearing to enter too deeply into 

 minutite, have hitherto been a desideratum whieh but very few have 

 the means, the patience, or the talent to supply.
