Bio\vning's Paracelsus and other Essays,- Bv J. D. 

 liuck. Robert Clarke Co., Cincinnati. 12mo., ])p. 101. 1S<)7. 



This little pocket volume containinj^- four short essays 

 is suitable to take along- these summer Sundays when 

 g-oing- into the woods or fields alone hoping- to feel the 

 touch of Nature. To read of Paracelsus, of Genius, of the 

 Music of the Spheres, or of Idols and Ideals while lying on 

 the grass amid the frag-rance of liowers or the hum of 

 insects will help to a g^lympse of what most men and 

 women never see and do not know to exist — something 

 non-material within, about and around the material form. 



I well remember my first experience of the "Music of 

 the Spheres" in Switzerland in 1895. Only he who has 

 heard it, however, will treat this essay as other than 

 imaginative. He who wishes with sufficient earnestness 

 to sense it can perhaps get assistance from this fjook. 



The azure-blue cover and the g-ilt top make Dr. Buck's 

 book a neat little ])resent. The i)rice is probal)ly not over 

 fifty cents.
