number of colonies; Agar ag-ar, 7,967 ; g-lycerine agar,

 agar shows the highest number of colonies. The average 

 number of moulds from air was as follow^ : On agar 

 agar, 3, glycerine agar, 7 ; beef gelatine, 20 ; wort gelatine, 

 34. Ten tests of water gave : Agar agar, 12 ; glycerine 

 agar 15 ; beef gelatine, 60 ; wort gelatine, 88. Ten tests 

 of milk gave : On agar agar, 2 ; glycerine agar, 7 ; beef 

 gelatine, 12 ; wort gelatine, 47. Wort gelatine showed the 

 highest number of colonies of moulds. Hence, statements 

 of the number of forms found, are of little value unless 

 the media are taken into consideration.

The Double Man. — This story reminds us of the novels 

 of Bulwer, being filled with information of the sort that 

 most men refuse to accept as truth and with recitals 

 which most men declare to be imaginary. The very 

 knowledge that most of all we shall sometime wish to 

 have is covered under the false label of fiction. We now 

 only amuse ourselves and forget the tale. Send fifty cents 

 to Paul Tyner Denver, Colo., therefore and be amused 

 with what he writes of man's powers in the occult realm.
