were obscured by the same mysterious visitation. The human intel- 

 lect may be, to a certain extent, compared to the dew-drop in the 

 sun-beam, — the brighter it shines, the more rapidly it fades away ! 



Dr. Henry was 61 years of age. He died on the 2nd, and was 

 interred on Wednesday morning the 7th of September, 1836, in the 

 burial-ground of the Chapel in Cross Street, Manchester, and his 

 coffin was deposited upon that of his distinguished father. 



This very hurried and equally imperfect tribute has been drawn 

 up by one who has reason to cherish Dr. Henry's memory with 

 mingled feelings of gratitude and admiration. At a period when 

 the pressure of his loss is so heavily felt by those who could 

 appreciate his talents and estimate his worth, it is impossible to do 

 justice to his character. When the agitation of grief shall have 

 subsided, his career and his virtues will, we trust, be detailed by an 

 abler pen, under more favourable circumstances. 



III. — Artificial Production of Metallic Sulphurets, <^'c., by 

 Electrical Action. 



The Geological Section of the " British Association for the Advance- 

 ment of Science," having received as novelties some communications 

 on this subject, we think it due to M. Becquerel to state, that he 

 obtained by this means a very considerable number of substances, 

 above seven years since. His apparatus consisted of a tube bent into 

 a syphon shape U, the curved portion being filled with moistened 

 clay, (I'argile pumectee,) and the legs with solutions of the substances 

 of which combinations were sought, and connected by a wire. 

 The crystalline metallic bodies which he obtained were. 



Metallic copper. 



Red oxide of copper. 



Vitreous copper. 



Grey copper (fahlertz). 



Metallic silver. 



Vitreous silver. 



Chloride of silver. 



Sulphuret of lead. 



Carbonate of lead. 



Sulphate of lead. 



Oxy-sulphuret of antimony (kermes). 

 Besides a considerable number of alkaline sulphurets, chlorides, 

 bromides, and many double sulphurets, salts, &c. 



Full details will be found in M, Becquerel's work '' de I'Elec- 

 tricite et du Magnetisme, Tome i., 332 — 350."

Twenty-third Annual Report of the Council. 



During the past year considerable additions have been made to the 

 Museum and Library, and the funds of the Society continue in a 

 prosperous state : but the council have the painful duty to report 

 that the quarterly meetings have been discontinued in consequence
