Zebra-Horse Hybrids. — I have just read, in the 'Bulletin de la 

 Societe Nationale d'Acclimatation de France ' (October, 1898), the translation 

 of the article published in ' The Zoologist ' (1 898, p. 49) on the hybrids of the 

 Burchell Zebra and mare by Prof. J. Oossar ft wart. I have perused this 

 memoir with much interest, because you will see by the publications I forward 

 that I &lso have crossed the Zebra and mare. Until now I believed that I 

 was the only one who had obtained this production, but by the article in 

 question I see that I am not ; and besides, my first production was born 

 three and a half mouths after that of Prof. Ewart's — my first, Sordello, 

 being born Dec. 5th, 1896, and Prof. Ewart's Romulus Aug. 12th, 1896. 

 It is very curious to note that neither of us has known of the other's 

 writings and ideas, yet have both carried into execution these experiments 

 within a few months of each other. At this moment Prof. Ewart is the 

 first in Europe, and myself the first in America, who have obtained these 

 hybrids by crossing the Zebra with the mare, or, rather, other writings on 

 the subject are unknown to me. I send you some photographs of my 

 first two hybrids, but have not yet any of the others ; but when I have will 

 forward them to you. I am writing also to Prof. Ewart, and sending the 

 same documents and photographs. 



La Societe Nationale d'Acclimatation de France has published, in its 

 Bulletin of October, 1897, my accouut of " Le Croisement du Zebre avec 

 la Jument." 



Dr. Fr. Steinriede published, in the ' Landwirtschaftliche Presse ' of 

 Berlin (Oct. 15th, 1898), an article with illustrations made from photo- 

 graphs of Zebra-Horse hybrids which I sent him. 



The 'Journal l'Eleveur de Paris,' No. 726 (Nov. 27th, 1898), published 

 a translation of a communication on the subject which I contributed to the 

 ' Societe Nationale d'Agriculture Bresilienne.' — Baron de Parana (Porto 

 Novo do Cunha, Rio de Janeiro).

 Nesting of the Mistle-Thrush. — This bird {Turdus viscivorus) is 

 much more common here than it used to be thirty years ago. On April 

 26th, 1888, I found a nest with four eggs, and the bird sitting on it, in a 

 hole in the stone pier of a field-gate near Clogher Head, Co. Louth. The 

 gate was often used, and the bird was sitting within six inches of it as it 

 swung. There were plenty of high hedges and trees quite close. I con- 

 sider this the most extraordinary and abnormal place 1 ever found a nest
