 Miscellaneous items. Personal. Dr. Rokiiro Nakaseko 

 (M.S., Yale: Ph.D., Johns Hopkins) has lately been a visitor in this

 exhibits, at the San Francisco meeting of the Amer. Med. Assoc, 

 granted a gold medal to Dr. M. H. Fischer, for his exhibit on Newer 

 experiments in the physiology and pathology of kidney functions. 



Lab. kinks. Method of paraffining labeis. Instead of going 

 to the trouble of melting paraffin whenever you wish to apply this as 

 a protective coating, the paraffin can be dissolved in carbon tetra- 

 chlorid, making a saturated sol. This may be applied as a varnish. 

 The carbon tetrachlorid evaporates, leaving a coating of paraffin 

 behind. Gasoline or benzine might be used but carbon tetrachlorid is 

 preferred, as its vapor is not inflammable. D. L. Randall : Chem- 

 ist- Analyst, 1915, no. 13, p. 25. 



Cleaning Solution for glass and porcelain. The following sol. 

 for removing org. material from glass- or porcelain-ware has been 

 found by the author much superior to the well-known potassium- 

 bichromate-sulfuric-acid mixture. The glass- or porcelain-appar. to 

 be cleaned is placed in a large evap. dish containing sulfuric acid and 

 a little nitric acid. If the appar. is not completely immersed, it is 

 turned after a few minutes so that the cleansing sol. comes in con- 

 tact with every part. The acid should be kept very warm but not hot 

 enough to evolve sulfur trioxid or to distill the nitric acid. Thick 

 glassware, e. g., suction flasks, should be placed in the cold mixture, 

 which is then heated. The sol. is permanent except that enough 

 nitric acid must be added, from time to time, to keep it white or at 

 least yellow in color rather than black. This mixture has been found 

 especially useful in cleaning dyes, gums and waxes from glassware.
