made. The rowers from practice calculating the length of 

 time the chace has lasted, can tell very nearly -whenever 

 the bird dives how many strokes of the oars will bring the 

 boat near the place where it may be expected to rise, and 

 by giving out this notice and counting aloud, the interest is 

 kept up throughout the pursuit, till a fortunate shot gives 

 the fatal blow, when the prize is handed into the boat, and the 

 telescopes again put into requisition to find out a new victim. 



The Great-crested Grebe is found in Provence and in 

 Italy. The Zoological Society have received specimens sent 

 by Keith Abbott, Esq. from Trebizond. Dr. Andrew Smith 

 brought examples from South Africa, and it is found in 

 several parts of Asia. Dr Richardson found this bird during 

 summer on most of the lakes of the fur-countries of North 

 America, and the species is included in the histories of the 

 Birds of the United States. 



In the adult male the bill is brownish-red ; the irides red ; 

 the top of the head, and the elongated feathers of that por- 

 tion of the crest on the crown of the head, rich dark brown ; 

 the cheeks white ; the long feathers forming together the 

 tippet, and part of the crest standing out from the sides of 

 the neck are reddish-chestnut at the base, becoming dark 

 chestnut at the end ; the neck behind, as also the back, 

 wings, rump, and the short tuft-like tail, dark brown ; the 

 secondaries white, but this colour is little seen unless the 

 wings are extended ; front of neck, and all the under surface 

 of the body delicate and shining silky white, from which, as 

 before mentioned, this species is sometimes called the Satin 

 Grebe ; sides beneath the wing and the flanks pale chestnut- 

 brown ; legs and toes dark green on the outer flat surface, 

 lighter pale yellowish-green on the inner surface ; the Avhole
