The decrease in the supply during the past year was due to 

 diminished receipts from Denmark, Germany, Italy, and Austria, 

 while the receipts from Russia and France increased. 



E. BROWN. Declining Import of Eggs in Great Britain. Re- 

 port on the Poultry Industry of 1909. Nature, Vol. 83, p. 167, 

 April 7, 1910. 



The decline in the import of foreign eggs, which has been 

 going on since 1903, still continues, not so much as a result of 

 incrtased home production as of increased requirements by Ger- 

 many, now the largest importer of poultry produce in the world. 



It is urged that farmers and small holders have now an oppor- 

 tunity in connection with poultry raising such as they never had 

 before.

This paper contains the results of 17 year's breeding with many 

 types of canaries. The author considers that diversity of type has 

 arisen from crosses between cinnamon sports and the wild green 

 bird. This theory is advanced from (i) a study of wild sports in 

 nature and in confinement, (2) cinnamon and cinnamon bred hybrids 

 which frequently show characteristics of canary varieties arising de 

 novo, (3) collateral evidence of a similar nature in poultry and pi- 

 geons, and from (4) a study of the earliest canary literature. 



Mendelian inheritance in canaries is discussed at length. Dark- 

 eye and pink-eye are found to behave generally in Mendelian fashion, 

 for it is evident that there is a homozygous type of dark-eye canary 

 and also a heterozygous or impure form occurring in the male as 

 well as the female. There is some evidence that the female of 

 the homozygous type of dark-eye canary is homozygous as well as 

 the male. Other characters which are seen to behave as recessives 

 are buffness and crest-bred plain-headedness ; their corresponding 

 qualities (yellowness and crestedness) exhibit more or less imperfect 

 dominance. The majority of crests appear to be heterozygous with 

 respect to crest. 



Some of the results obtained by Davenport are stated to be 

 different from those of the author, because of the breeding stock
