Gentlemen, — As most copies of this little work are wrongly bound 

 up, it may be useful to print this list of contents of the several parts

 Phthirirts," which is an addition, and " Lystra Phenax" (4 pp. of 

 small type), which seems to be a correction, — but I suggest they 

 both date from the 10th Heft, 1846.
