A. Department for Precision Balances and Weights. 



I. Rapidly oscillating universal Precision Balance; is sub- 

 -stancially a high precision balance, for the determination of weights up 

 to 500 grammes (resp. 1000 grammes) which, as such, comes fully up to 

 modern requirements, but, at the same time, offers this specific ad- 

 vantage, that it enables one to determine smaller weights (up to 100 or 

 150 grammes) with the same degree of rapidity and consequently, for the 

 ordinary routine of the analyst, affords the same degree of convenience in 

 use as an ordinar}' quick working analytical balance of small carrying power. 



Fitted with Prof. Dittmar's gravity-bob and reading microscope. 



Beam of aluminium bronze, highly gilt and having cross-knife- 

 edge suspensions. All knife-edges and planes are of agate. The axes of 

 rotation are conveniently in sight. 



No. 1. Universal -balance to carry 100 1000 grammes in 



each pan, in elegant case of mahogany, walnut (or imitation) 

 Sensibility 0,1 0,01 Milligrammes.
