The Naturalists' Pocket Calendar. By Stanley Bngg and Arthur 

 Holliei. London: W. E. Bowers, 1888. 



This neat little calendar will be found useful to those who are 

 accustomed to note the times and seasons. It gives the times of 

 migration, nidification, etc., of birds, and the habits of animals, 

 fishes, reptiles and insects for each month in the year. Finally, 

 there is an interesting and curious table of weather warnings, a 

 page or two on " Plants as Weather Guides," and a statement 

 regarding barometric readings. It is well worth the three pence 

 asked for it.

 is largely due the credit for the clean proof and acceptable 

 appearance of the volume.
