CRYSTALLIZATION OF PHOSPHORUS. 



By the fusion and careful refrigeration of a large quantity of phos- 

 phorus, M. Frantween has obtained very fine crystals of an octahedral 

 form, and as large as a cherry-stone. 



CHEMICAL EXAMINATION ON ANCIENT INSTRUMENTS, &C. 



M. Vauquelin has analysed a poignard blade, formed entirely of 

 copper; a mirror found to consist of 85 parts of copper, 14 tin, and 

 1 of iron per cent ; and a blue colour found in a tomb, gave by 

 analysis, silica 70, lime 9, oxide of copper 15, oxide of iron 1, soda 

 and potash 4. A blue colour similar to this both in tint and com- 

 position, was found in the bottom of a furnace in which copper had 

 been fused at Romilly. — Bull. Univ. A. vii. 264. 



LONDON INSTITUTION. 



Encouraged by the success of the Royal Institution, the managers 

 of the London Institution propose, during the present season, to try 

 an experiment which they trust will prove acceptable to the proprie- 

 tors. 



The library and theatre of the London Institution will be prepared 

 during eight evenings for a soiree or converzatione, to which pro- 

 prietors and their friends will be admitted under certain regulations. 

 Coffee and tea will be supplied in the library, where it is intended to 

 introduce all new scientific inventions or discoveries, that can be ex- 

 hibited by models or drawings. New literary works, original draw- 

 ings, and scarce books, will constitute another source of interest and 

 information. This plan will be attended with the advantage of intro- 

 ducing learned foreigners and men of science to a complete view of 

 the establishment, and to a social conversation with its managers and 

 proprietors. At some period during the evening an adjournment will 

 take place to the Theatre, where it is intended to give a short dis- 

 course or lecture, either honorary or professional, on any new ma- 

 chinery, or on any chemical, philosophical, or literary novelty that 

 may be considered by the managers to deserve the attention of the 

 Institution. 



The following is a notice of the series of lectures for the season, to 

 be delivered in the Theatre of this Institution: —
