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. 



37O. Balance for chemical and physical purposes. 



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



These three instruments, together with No, 368, and 369 are chiefly used 

 in forestry and agriculture. 



Balance of the firm's own construction ; capacity of weighing, one kilo- 

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

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

 terminating edges consist of steel, and all supports of hard stone. The weight 

 of the beam with edges is = 7 93 grammes ; flexion of the beam at 1 kilogr. 

 weight on each scale = 0'14 mm.; at 1,500 kilo. weight=0-028 mm.'; at 

 2-000 kil. weight=0'042 mm. at 3'000 kil. = 0'070 mm. A permanent flexion 

 has not been observed at such a weight. 



375. Ten Plates of Bock Crystal for Balances. 



Hermann Stern, Ober stein. 



376. Chemi co-physical Balance, executed by Ch. Jung, 

 in Giessen. 



Collection of Physical Instruments of the University of 



Giessen (Prof. Dr. Buff). 



By shortening as much as possible the beam (balance) these scales oifer 

 the advantage of great flexibility and sufficient rigidness to weigh accurately 

 from 250 grammes to -5^ 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, adjusted according to the directions of the Imperial German 

 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. 



The practical employment and use of the apparatus for scientific and 

 technical industries, in the first instance, and next for the solution of national- 

 economical problems, will be demonstrated by two continuous memoirs, 

 published by the Imperial Commission for Normal Weights and Measures.
