if we take from white light a given colour the remaining colour 

 is the complement of the given colour.' When any two colours 

 or hues which when combined in proper proportion on the 

 colour-wheel produce, by rotation, neutral grey, these two colours 

 each represent the complementary of the other." 



Now that wattle-blossom has been proclaimed Austraha's 

 national flower, Austrahans especially wih be interested and 

 instructed in a number of new names in the scale of yellows, such 

 as baryta, martius, pinard, picric, massicot, naphthalene, chal- 

 cedony, marguerite, chartreuse, &c. King's yellow is missed, 

 but instead there is an " empire yellow," of similar tint.

NORTH QUEENSLAND BIRDS. 



The Editors of The Emu. 



Sirs, — Dr. W. Macgillivray, in his most interesting paper on 

 the birds of Northern Queensland, in The Emu, January, 1914, 

 remarks that it is doubtful whether the nest and eggs of Podargus 

 marmoratus have been obtained. I wish to state that I described 

 the nest and egg in The Ibis for July, 1899 (page 361). Dr. Mac- 

 gillivray also mentions that the eggs of a Cuckoo were found in 

 the nest of Glyciphila modesta, and he presumes that they were 

 those of CacoDiantis variolosiis. He is right in his contention, 

 as in 1898 I left an egg of the Cuckoo in the nest of foster-parents 

 until it was hatched and the fledgeling was able to leave the nest. 

 I then secured the specimen and brought it to Melbourne. It 

 proved to be the young of the above-mentioned species.
