Miscellanies. 187 



1.4. American Botanical Register. — The nature and object of this 

 work, were announced at p. 160, of our last volume, to which no- 

 tice, we refer our readers. 



We have now to state, that in accordance with the pfen, No. 1 of 

 the work has appeared, and the numerous colored engravings beau- 

 tifully executed, have fully redeemed the engagements of the editors 

 on that head. We trust that the work will prove useful to the ad- 

 vancement of botanical knowledge. 



15. Encyclopedia Americana. — The seventh volume of this val- 

 uable work has been published, and is occupied by parts of the let- 

 ters I and L. It is pleasing to see it appear with such punctuality, 

 and to observe the rich additions that are made on American topics 

 which cannot fail to render it both more useful and more interesting 

 to American readers. In the account of the New Haven and Farm- 

 ington Canal some slight errors have crept in ; Colebrook is remote 

 from the line of the canal, which, instead of being merely under con- 

 tract to Southwick, has been, for several years, navigable to that place, 

 and beyond it to Westfield, in Massachusetts. 



Messrs. Carey and Lea have republished a series of articles from 

 the Encyclopedia, relating chiefly to France; thus a valuable mass 

 of information respecting that fine country, now so peculiarly inter- 

 esting to the world, has acquired a wide diffusion. 



16. Tables for determining the latitude at sea by ah altitude of 

 the polar star, observed at any distance from the meridian. — The 

 naval profession is indebted to Mr. J. P. Rodriguez of the U. S. 

 Navy Yard at Gosport, for the very useful tables named above ; 

 frorii their source we cannot doubt of their accuracy, and every thing 

 of this kind is particularly interesting, in a country which is eminent- 

 ly the land of ships and seamen. 



17. Science in the West. — Useful knowledge is advancing in these- 

 favored regions with the general progress of society. We have 

 already mentioned the Detroit Lyceum, and, in a large, handsome, 

 and well arranged newspaper, — The Detroit Journal and Michigan 

 Advertiser, — we observe a discourse or lecture, pronounced in May 

 last before that institution, by Mr. Schoolcraft; it is interesting and 

 instructive, and replete with the personal knowledge, acquired by 

 that gentleman in his extensive travels, in the interior of this conti-
