prominently forward under the arrangements of the new County 

 Councils. The above named treatise has been called forth by the 

 demand for a reliable text-book, and it is well that the preparation of a 

 work, the importance of which will year by year become more evident, 

 should have been taken up by such able hands. The text-book is 

 practically a new work and provide-; ihe English caltlvator anl agricul- 

 tural student with a concise book of reference by means of which he 

 can identify any injurious insect or its attack, which is likely to occur 

 on his crops. We think that too high praise cannot be expressed for 

 the manner Miss Ormerod has fulfilled her self-imposed task. The 

 language is so simple and concise ; and yet each detail is so scientifi- 

 cally accurate, that the danger of making mistakes in the identificitions 

 seems quite impossible. Miss Ormerod, from her long experience, 

 perseverance, keen observation, and natuial aptitude for this special 

 work, has mide herself the highest authority on Economic Entomology 

 in Europe; in fact, she holds among the Entomologists of the old 

 world, the same relative place as Prof. C. V. Riley on this continent. 

 Miss Ormerod does not profess to be what is called a scientific ento- 

 mologist, but we claim that she is scientific m the truest sense, in that 

 she shows in all her writings a determinatioi to have perfect accuracy 

 before everything else ; she spares no trouble to attain that end, and 

 her one object is manifestly to discover as soon as possible the complete 

 life-history of any pest she may have under consideration and the most 

 efificient and practical means of checking its injuries to farmers or 

 others.

The above work has been received, an J it certainly is what it 

 professes on its title page to be, "an exhaustive monogra|)h, popularly 

 written." Tne author must have spent much time in the collection of 

 the numerous facts which he now gives to the public in this most 

 attractive work. It would be hard to find any subject co mected with 

 Beaver lore or with the natural history of the animal, which has been 

 omitted. The illustrations, which are profuse and for the most part
