 dislodged. 



We shall not attempt to follow Dr. Cobbold into the second de- 

 partment of his work, in which he treats of those helminths which are 

 peculiar to the human body. The following list of human entozoa, 

 as the most complete hitherto published, may, however, prove of 

 interest to many of our readers : —

We have endeavoured to indicate the comparative frequency of the 

 occurrence of these worms in the human body. The number of single 

 and very rare cases shows that there is much to be done by subsequent 

 observers, and that this field of observation invites further investiga- 

 tion, which will be rewarded by its practical utility. We must now 

 close our notice of Dr. Cobbold's book, by recommending it to the 

 study of all who are engaged in the investigation of the Entozoa.
