LIQUID AIR AND LIQUID HYDROGEN. 



Dr. HAMFSON'S AIR-LIQUEFIER is now made to a standard pal- 

 tern, and numbers are in use in University Laboratories and elsewhere in 

 various countries. The whole apparatus is neat and compact and its parts 

 very easily moved ; the Liquefier, without stand, being a cylinder 17 Inches 

 hich and 8 inches in diameter. 



It begins to liquefy air in from 6 to 10 minutes after the admission of air 

 at from 150 to 200 atmospheres pressure, making over a litre of liquid per 

 hour. 



It requires no auxiliary refrigerant and produces a perfectly cleat liquid 

 which requires no filtering. 



The operator has only one gauge to watch and one valve to control. 



HYDROGEN LIQUEFIER to the designs of Dr. MORRIS W. 

 TRAVERS for use in conjunction with Air-Liquefier.
