Becker's Test. A test for astigmatism, made by means

Beckmann, Method of. A method for the determination 

 of the depression of the freezing-point. A hard glass 

 tube, from 2 to 3 cm. in diameter, with a lateral pro- 

 jection, is filled with from 15 to 20 grams of the solvent 

 (weighed out accurately in centigrams), and closed 

 with a cork in which are placed an accurate ther- 

 mometer and a stout platinum wire serving as a stirring- 

 rod. The lower part of the tube is attached by means 

 of a cork to a somewhat larger, wider tube, which 

 serves as an air-jacket. The entire apparatus projects 

 into a beaker-glass filled with a freezing-mixture. Cold 

 water will answer for glacial acetic acid and ice-water 

 for benzene. The congealing-point of the solvent is 

 determined by cooling this to from i° to 2° below its 

 freezing point ; then by agitation with the platinum 

 rod (after addition of platinum dippings} the forma- 

 tion of crystals is induced. The thermometer rises. 

 When the mercury becomes stationary, the reading in- 

 dicates the freezing-point of the solvent. The mass is 

 allowed tii melt and an accurately weighed amount of 

 substance i- introduced through the lateral projection. 

 When this has dissolved, the freezing-point is de- 

 termined a- before.
