Hugo Schickcrt, Dresden. 



363. Fine Assay Balance for weighing 20 grammes, turning 

 with I/ 100 nig. G. Westphal, Celle. 



364. Large Balance for determining the specific gravity of 

 liquids. G. Westphal, Celle. 



365. Large Balance used in the Manufacture of Sugar. 



G. Westphal, Celle. 



366. Small Balance for determining the specific gravity of 

 liquids. G. Westphal, Celle. 



367. Pharmaceutical Balance, for simple chemical opera- 

 tions. G. Westphal, Celle. 



370. Balance for chemical and physical purposes. 



C. Staudinger and Co. (F. W. von Gehreri), Giessen. 



Balance of the exhibitors' construction ; capacity of weighing, one kilo- 

 gramme on each scale ; sensitive at this weight, to 0-4 milligr. The balance is 

 made of one piece of wrought (not cast) brass, and gilded. The centre and 

 terminating knife edges are of steel, and all supports of hard stone. The 

 weight of the beam with knife edges is = 793 grammes ; deflexion of the beam at 

 1 kilogr. weight on each scale = 0' 14 mm. ; at 1-500 kilo. weight=0'02S mm. ; 

 at 2-000 kil. weight = 0-042 mm.; at 3-000 kil. = 0*070 mm. A permanent 

 deflexion has not been observed at such a weight. 



375. Ten Plates of Bock Crystal for Balances. 



Hermann Stern, Oberstein. 



376. Cheinico-physical Balance, executed by Ch. Jung, 

 in G iessen. 



Collection of Physical Instruments of the University of 



Giessen (Prof. Dr. Buff). 



By shortening as much as possible the beam these scales offer the ad- 

 vantage of great sensitiveness and sufficient rigidity to weigh accurately from 

 250 grammes to -- milligrammes. 



377. Analytical Balance, executed by Stollenreuther. 



University of Munich. 



379. Standard Weights in Glass, executed by Stollen- 

 reuther. University of Munich. 



381. Model of a Balance for determining the quality of 

 grain, constructed according to the directions of the Imperial Ger- 

 man Commission for Standard Weights and Measures, with a 

 corn measure of 1 liter capacity. Reinhold Lohmann, Berlin. 



The manner of adjusting the several parts, as well as the successive series 

 of applications of the same, is illustrated and facilitated by an explanation, 

 with sectional and cross-sectional drawings, accompanying the model.
