plating, but M. Boistel, the representative in Paris of Messrs. 

 Siemens, informs us that the definite types are actually 

 in course of study. We shall not be able, therefore, to 

 publish the dimensions, weights,, and prices until our second 

 edition. 



SCHUCKERT MACHINE. M. Schuckert has selected as his 

 model a Gramme machine with a flat ring and inducting polar 

 surfaces almost entirely surrounding the induced wires, and he 

 has established, upon that model, a series of types suitable for 

 electric lighting and electroplating.*

Schuckert Machine. 



The Schuckert machine (Fig. 15) is largely used in Germany; 

 it is constructed with care, and the study of the types of a great 

 capacity is particularly successful. In general, the more the 

 maker has endeavoured to reproduce the parts and the shapes 

 of frame adopted by the inventor, the greater real practical 

 value of his machines. 



* M. Gramme having obtained no potent in Germany for his first machine, 

 M. Schuckert has been able to appropriate to himself the machine with flat 

 ring without running the risk of a commercial claim on the part of the inventor.
