ABSTRACT
In a work published by one of us in 1859, a close comparative examination was made of the doctrines of those observers, who in Germany and Belgium had occupied themselves with the subject of the metamorphoses of the Entozoa and their peregrination through the living organism. The obvious result of this examination was to excite very weighty doubts in every thoughtful mind. M. Davaine, in his remarkable ‘Traité des Entozoaires,’ also says that the conclusion in his mind, from the agreement in the facts and the divergence in the opinions of the experimenters, was “that the question still demands sound criticism and fresh researches.”
In the ‘Comptes rendus’ for June 2nd, 1862, is a letter from Prof. Van Beneden, in answer to some of the statements in the observations of MM. Pouchet and Verrier, and in the number for June 16th is a rejoinder from those authors, maintaining their former propositions. Of these papers an abstract will be given in our next. [Ed. M. J.]
