A paper was read by Major Eoss, R.A., " On Micro -crystals 

 and Iridescent Films obtained by the use of the Blow-pipe." 

 Major Eoss showed his method of operation. He melted borax 

 on a platina wire bent into a ring at one extremity, and then in- 

 troduced the various metals. By employing a mechanical blow- 

 pipe to maintain the borax bead in fusion, he was able to blow it 

 into a thin bubble by means of an ordinary mouth blow-pipe. The 

 borax bubbles exhibited iridescent colours, and after being left 

 for some sime undisturbed micro-crystals made their appearance. 

 Major Eoss thought that the coloura of the films and the forms of
