which are sometimes placed outside, I should suggest, that be- 

 tween the frame and the painted glass there should be a screen 

 of ground-glass. In this case the form of the stud would re- 

 quire to be as in Fig. 7, by which the panes of ground-glass 

 would be fixed in the same manner as the painted ones, and 

 the effect of the shadows so much dispersed as to be nearly 

 invisible to an eye inside of the building.

Since leaving England we enjoyed an almost uninterrupted 

 course of fine weather, but from the beginning of February, 

 when we left the northern tropic, till our arrival in the Colum- 

 bia River on the 8th of April, we were exposed to the 

 N.W. gales, which at this season render the approach to the 

 shores of New Albion extremely dangerous. During the 

 stormy weather many albatrosses were seen near the vessel ; 

 and on the 17th February we succeeded in procuring several 

 individuals. It is a remarkable circumstance, that in works 

 on Zoology this bird is always mentioned as peculiar to the 

 southern hemisphere. Although the occurrence of the bird 

 in the N. Pacific has attracted but little attention, it was ascer- 

 tained long ago by Mr Menzies, and is recorded in Vancou- 

 ver's Voyage. It is also worthy of notice, that though the al- 

 batross is so common in both sides of the tropics in the 

 Pacific, no one, as far as I am acquainted, has ever detected 

 it in the Northern Atlantic Ocean. After repeated examina- 

 tions and dissections, we could detect no difference either in 

 its external appearance or internal structure, from that of the 

 D.Juliginosa, taken off the coast of Tierra del Fuego.
