OTTO WOLTERS, 



55, UPPER MARYLEBONE STREET, PORTLAND 

 PLACE, LONDON, W., 



BALANCE MAKER 



(Many years with L. Oertling). 



SOLE MANUFACTUBEB, 



OF THE NEW 



SHORT-BEAMED ANALYTICAL BALANCES, 



A SPECIALTY which he has introduced into this country with 

 great success. In its present new improved form it has decided 

 advantages over any other Balances in existence, and chiefly recom- 

 mends itself by its quick action, which is great saving of time to the 

 scientific operator, and by its extreme sensitiveness and accuracy, while, 

 owing to the lightness of its beam, the friction and consequently the 

 wear of the knife edges and their supports are reduced to a minimum. 

 The capabilities of this Balance are such that it yields to the tenth 

 part of a milligramme with the greatest precision. 



A Description, explaining the principles of these Balances, Post Free on 

 Application. 



All Balances are adjusted by Mr. "Welters himself under 

 absolute guarantee.
