A Revision of the Lysiopetalidse, a Family of Chilognath Mjriopoda. 

 By Dr. A. S. Packard. 



In studying the cave fauna of the United States, the author of this 

 paper found it necessary to work carefully over the structure of the 

 Myriopoda. In this paper he gives a systematic account of the genera 

 and species pertaining to this group, describing also the characters of a 

 new genus, Cryptotrichus, followed by a chapter on the Morphology of 

 the Myriopoda, with a plate illustrating the mouth parts.

Human Parasites ; by Dr. F. W. Coding. From the Chicago Medical 

 Journal and Examiner for Dec'r, 1883. 



In this paper the author notices all the different species of para- 

 sites known to affect the human body both internally and externally, 

 grouping them in accordance with the latest system of classification, and 

 briefly giving the life history of each species as far as known, adding the 

 appropriate remedies and methods of treatment for each. The list is a 

 formidable one and goes far to confirm the statement made by the author 

 in his introductory remarks, that " scarcely any portion of the human 

 body is free from parasites, and each organ and system has its own special 

 parasites."
