will have forgotten that such a work was in course of publica- 

 tion. Four more parts have reached us, and we have only to 

 to complain of the way it lags towards completion. It may 

 possibly outlast the next series of ' The Ibis ;' but we know the 

 blame does not lie with the author. 



We are in possession of two more portions of Herr Holmgren's 

 ' Birds of Scandinavia'*, of which we noticed the first part more 

 than two years since (Ibis, 1868, p. 113). They are very fairly 

 done; but the plates at the end are old friends of ours, having 

 served to illustrate Strom's little ' Svenska Foglarna ' more than 

 thirty years ago — a fact of which we have not been able to find any 

 mention made by the modern author. The woodcuts also show 

 that the art of " crib " is not unknown in Sweden. Some inter- 

 esting particulars are given (pp. 725-727) of the attempts at 

 naturalizing Lagopus scoticus near Jonsered by Mr. Oscar Dick- 

 son, of Gottenburg, which are promising and will, we trust, be 

 successful. Since it seems by all accounts that the Common 

 Partridge was imported into Sweden, there is perhaps the greater 

 hope that the Red Grouse may thrive there equally well in cer- 

 tain localities. These two portions contain the Accipitres, Co- 

 lumbce, Gallince and Grallce : another part ought to complete the

 which has reached us from Denmark, though written in English f. 

 The author begins by explaining in the usual manner the way in 

 which a boat sails on a wind, and, thereon basing his explanation 

 of the mechanics of flight, assumes that the motions of wings
