PROF. P. MAGNUS. 



We dedicate this pamphlet to the memory of our late friend, Dr. Magnus. 

 We never visited Berlin without the pleasure of calling on him. He was an 

 old bachelor, and like all old bachelors, was no doubt a little cross, but we 

 have always found him most genial, and think he was not half as cross as 

 would appear from the photograph.
