B. VII.] THE HISTOKY OF ANIMALS. 193 



stoppage in the bowels. Children with this complaint gene- 

 rally die before the seventh day : wherefore also this day 

 has received a name, as if it gave some hope of the recovery 

 of the child. Children suffer most at the full moon. Chil- 

 dren are in great danger when the spasms originate in the 

 back, especially if they are advancing in age. 1 



1 The seventh book ends very abruptly, and hence it has been thought 

 that what is now called the tenth book, in which the subject of repro- 

 duction is continued, would have its proper place here, as a continua- 

 tion of the seventh. Whether a portion of the genuine work of 

 Aristotle has been lost which would have completed the subject is 

 another question ; but there can be little doubt that the tenth book, hi 

 the form in which we have it, is no genuine work of Aristotle ; some of 

 the opinions are contrary to those which he has expressed, and the 

 whole style and language is different from that of Aristotle. Schneider 

 therefore has placed the tenth book at the end of the work, that he may 

 neither entirely exclude that which in former times was considered a 

 portion of Aristotle's^ treatise on Animals, nor yet allow a fictitious 

 book to interrupt the genuine writings of his Author.
