establish, and to register them. — The contrary is the case with 

 magnetism. They reason, they dispute, but do not examine ; 

 they judge without having observed; conclusion comes before 

 experiment, instead of after ; and how manv prejudices, how 

 many prepossessions, how many interests produce these conclu- 

 sions ! It is impossible to mistake them in reading the opinions, 

 the decisions scattered through the periodical papers. If tlie 

 medical men and the wits (for wits too will argue on medicine) 

 would study the doctrine which they oppose, the tiuth of it 

 would soon be evident to them ; and we should then perhaps 

 hear them giving to ;Tiagnetism panegyrics as exaggerated as 

 their present criticisms.

P. S.— My Observations were in the press when a letter was 

 communicated to me of the Count de Loewenhielm, minister 

 plenipotentiary of the King of Sweden at the Court of Russia. 

 This letter bears date Stockholm, 7th October 1816, and the 

 person to whom it is addressed has given nie permission to tran- 

 scribe thence the following paragraph : 



*' I forgot to tell you that at Berlin Magnetism, known by the 

 name of Mesmerism, receives much greater honour than with 

 you or even with us. The King of Prussia has jtist appointed 

 Mr. Wolfart, Professor of Mesmerism in the Academy ; he has 

 also founded an hospital of a hundred wards for the wounded, 

 who are to be placed under exclusive magnetic treatment. 



" I have just learnt from M. de Cederschoeld, a very eminent 

 physician of Stockholm, whom I sent to Berlin at the expense 

 of the Court, that Mr. de Stoffregen, physician to the Empress 

 of Russia, and Mr. Malfatti, physician to the Court of Vienna, 

 are also sent to confer with Mr. Wolfart, and to leurn his prac- 

 tical system in the mode of using the baqiiet, a system founded 

 on the surest principles of approved medical science."
