254 SKETOHES OF EUROPEAN ORNITHOLOGY. 



The most effectual means of preventing, or, more properly speaking, 

 suspending the causes of decay which are inherent in wood and all 

 organized bodies, is effected by Mr. Kyan's method of applying a 

 solution of corrosive sublimate, which penetrates deeply into the wood, 

 and by solidifying or coagulating the albumen, thus prevents the com- 

 mencement of the fermentation, and the development of fungi, which 

 are not the cause of the sap-rot, as maintained by some, but the inci- 

 dental accompaniments, owing to their mucilaginous or saccharine 

 principles. 



The results from numerous experiments proving the durability that 

 this process confers upon timber are now becoming generally known. 

 The encouragement it receives from eminent professional men, who 

 are using it in executing their large public works, tends to convince 

 us of its utility ; but time alone will show to the world what is the 

 value of this great invention.

Part XV. — The first plate presents us with a rare species of 

 Eagle, one of the smallest, but not the least typical of the genus 

 Aquila ; viz. the Booted Eagle, Aquila pennata, Steph. — Aigle 

 botte, Fr. Eastern Europe and the adjacent portions of Asia con- 

 stitute the habitat of this interesting bird ; but it is said to migrate 

 annually into Austria, Moravia, and the eastern part of the German 

 territories. M. Temminck says that it breeds on the Carpathian 

 mountains. The figure represents the bird of the natural size, and 

 this is much less than that of the Common Buzzard. The attitude 

 we cannot admire : the breadth of shoulders alluded to in the descrip- 

 tion is not given in the figure ; there is no freshness or spirit in the 

 drawing ; the port and aspect are not those of the daring, the impe- 

 tuous Eagle.
