"Of the manner in which this work is executed, we can say that, like Miss Catlow's previous productions on Natural History, it displays an accurate acquaintance with the subject, and a keen delight in the contemplation of the objects to which it is devoted. As far as the living beings which inhabit 'Drops of Water' are concerned, we know of no better introduction to the use of the microscope than the present volume."—Athenæum.
