4 ' The value of its method lias been fully tested, and the many works 

 which have appeared since and have applied the plan in various depart- 

 ments show how perfectly it meets the needs of the day. ... It marked 

 the beginning of a new era in studies upon living organisms an era where 

 the study of isolated parts was largely discontinued and the organism began 

 to be studied in its entirety. In this regard it seems to us that the Practical 

 Biology is far superior to most of the later works which have been designed 

 to partially or wholly supplant it." Microscopical Journal. 



" Huxley and Martin's ' Practical Biology ' has long since won an envia- 

 ble place as a text-book in our best institutions." Scie nee.
