and base, it would have been a subsesqui-pectate ; the author, never- 

 theless, states that this salt gives the same composition for pectic 

 acid as the pectates of silver. — R.P.] 



Pectate of Copper was obtained by adding a solution of sulphate 

 of copper to one of pectate of ammonia ; the compound is a bright 

 green jelly, which, after drying till it loses no more weight, forms a 

 yellow mass. This salt was not of a constant composition. It was 

 also attempted to be procured by decomposing a very ammoniacal 

 pectate by sulphate of copper. The compound remained long dis- 

 solved ; at last it formed in intense blue jelly, which could not be 

 obtained free from ammonia, even by long washing ; it was evidently 

 a double salt. — Journal de Pharmacie, xxiv. 205. 



PORTRAIT OF PROF. FARADAY. 

 Our readers will be gratified by learning that a half-length en- 

 graving of Professor Faraday will be immediately published by 

 Mr. C. Turner, A.R.A., Warren-street, Fitzroy-square. The like- 

 ness is most successful, and the expression admirable ; it gives us 

 not only his character, but figure, and is taken as he is usually seen 

 when delivering his lectures.

 LinnKan Society.
