PUBLICATIONS RECEIVED. 



Gleanings from jValure, No. i. Oo/ogica/ Ab?wrmai;lies. By J. 

 Warren Jacobs. This is the first of "A series of pamphlets based 

 chiefly on the author's research in ornithology and oology and pub- 

 lished from time to time as accumulating material and data permits." 

 In the preparation of this pamphlet "Over one hundred sets of eggs 

 [no], each containing one or more abnormal specinens, have been bro't 

 together along with the copious notes appertaining thereto. Care has 

 been taken to incorporate in the paper only such notes as have been 

 properly authenticated and are based wholly on adnormal sets in the 

 author's possession." 



In the first si.xteen pages of this pamphlet the author presents in tabu- 

 lated form both the average size of a number of normal eggs and the 

 actual measurements of abnormal ones ; and discusses briefly some of 

 the reasons for the production of abnormalities in "Size," "Color," 

 "Contour." In the remaining twenty pages the no sets in which ab- 

 normal specimens are found are carefully described, and the abnormal 

 features are made to at once appeal to the eye by being set in italics.
