Lichens. 

 (By A. Lorrain Smith, F.L.S.) 



Chemical Examination of Lichens.* — Emanuel Senft finds that 

 the ordinary methods of extracting- acids from lichens by chloroform, 

 etc., are too rapid in action, and that they evaporate too quickly. He 

 has discovered, however, a method which* he recommends of using fat
