 Artificial Respiration for Saving 

 New Born Babies 



807 



A DEVICE that is effective in saving 

 the life of new born infants who do 

 not breathe properly, or fail to start 

 breathing at all, 

 is a special lung- 

 motor with a ca- 

 pacity and an op- 

 erating mechan- 

 ism suited to the 

 needs of the 

 patients. 



A mask pad 

 fits closely over 

 the face, while 

 the operating 

 mechanism is 

 clamped to a 

 table so as to be 

 operated by one 

 hand. The air 

 goes into the 

 lungs of the child 

 at a very slight 

 pressure. Fresh 

 air enters by one 

 passage and the 

 expired air leaves by another so that they 

 cannot mix. The lungmotor can be set at 

 any one of three different capacities for 

 different sized babies. 



The lungmotor for the smallest human patients. 

 Air enters by one passage and passes out through another 



likely to be attracted by the little tassel 

 that depends from your button.. He takes 

 hold of this in a friendly spirit and is 

 much astonished to see a ribbon roll out 

 on which are printed the words,' 'I belong 



to No. , where are you from, Bill?" 



At the same time 

 a little bell rings 

 merrily. If the 

 wearer of the 

 badge is an Elk, 

 the bell rings 

 eleven times. 

 This mystifying 

 performance as- 

 tonishes the 

 friendly stranger. 

 The communi- 

 cative badge is 

 a very simple de- 

 vice. The bell- 

 ringing mechan- 

 ism and the 

 winding spring 

 are merely a little 

 set of watch pin- 

 ions with a 

 ratchet and a 

 bell. These fit 

 into the space on the underside of the 

 button. The ribbon is wound up on a 

 tiny drum, as indicated in the illustration 

 below. 



A Badge Which Tells the Story of A Parsec— the Greatest Known Unit

IF you are thinking of attending one of \ "PARSEC" is a distance that the

 Elk or Moose, get 

 yourself one of the 

 new explanatory 

 badges. A California 

 man once went to 

 such a convention 

 and got so tired telling 

 others where he came 

 from that he went home 

 and invented the new 

 badge, which tells the 

 whole tale. 



This badge looks like 

 any ordinary celluloid 

 button but it does not 

 behave like one. When 

 the curious stranger

 years. A few of 

 the nearest stars are 

 from one to five 

 parsecs distant 

 from us, but most 

 of the stars that dot 

 the sky are scores 

 or hundreds of 

 parsecs away.
