state of tlie atmosphere for its efficiency, nor require almost 

 any expense to produce or continue its actions. 



To construct it, however, on a large scale, a considerable 

 quantity of wire, covered with an insulating substance, is re- 

 quired. The covering of the wire is at present, I believe, ex- 

 pensive, but a machine I constructed for the purpose, which 

 leaves nothing to the care or skill of the operator, ahnost no- 

 thing to his labour, and which may be applied to many branches 

 of manufacture, has changed what would otherwise be trouble- 

 some and laborious into the work of a few moments. Some 

 judgement ma}' be formed of the rapidity of its execution when 

 I mention that very lately I covered with it 20,000 feet of 

 wire of various diameters; and of the exactness with which it 

 covers it, by the nearly 1300 feet employed in the apparatus 

 submitted to the Society.

LXXXV. On the Art of Glass-Painting. 



By A CORRKSPONDENT. 



A S the accounts to be found in various works respecting this 

 -^^ curious art are by no means satisfactory or complete, I 

 have thought that a few observations on the subject, com- 

 prising a concise account of the processes employed, both in 

 ancient and modern times, might be deemed of sufficient in- 

 terest to obtain a place in the Lond. and Edinb. Philosophical 

 Magazine. 



It is a singular fact, that the art of glass-painting, prac- 

 tised with such success during former ages from one end of 

 Europe to the other, should gradually have fallen into such 

 disuse, that in the beginning of the last century it came to 

 be generally considered as a lost art*. In the course of the 

 eighteenth century, however, the art again began to attract 



* [Our Correspondent will doubtless be glad to learn that a very able and 

 interesting work on Glass-Painting has lately been published at Rouen, 

 entitled, " Essai Historiquc et Desvriplif sitr la Peinivre sur Verre ancienne 

 et moderne, et iur les Vitraux les plus remarijuables de quelques monumens 

 Fratifais el etrangers; sidvi de la Biographic des plus ci'lebres Peintres- 

 Verriers: Par E. H. Langlois, du Pont-de-1'Arche, orne' di Planches des- 

 sinees et gravees par Mademoiselle Esperance Langlois, ]H32." The beau- 

 tiful and curious windows of the churches of St. Godard, the Cathedral, 

 St. Ouen, St. Patrice, and St. Vincent in Rouen have been copied by Ma- 

 demoiselle Langlois with great spirit, skill and faithfulness. 



M. Langlois disproves the notion ('-raveugle prejuge"), that the art had 

 been lost, p. 193; and states that this error was more unaccountable in 

 England, where, according to one of the memoirs of M. Al. Brongniart, a 

 number of the finest windows were painted from 1616 to 1700, and by 

 Jervis Forrest up to 1 785. — R. T.J
