9. Elementary works on astronomy.— Elements of Astronomy,” 
by Hervey Wilbur, A. M.—* View of the Heaven,” by Rev. Amos 
Pettengill. 
The two foregoing elementary treatises on astronomy have been re- 
cently published, being severally designed to furnish to young learners 
an easy introduction to the instructive and delightful study of the 
heavenly bodies. The treatise of Mr. Wilbur, who is extensively 
and advantageously known as a popular lecturer on astronomy, is in- 
tended more particularly as a companion to his lectures; while that 
of Mr. Pettengill is especially adapted to the srrLLaroTa—an in- 
genious and very useful instrument, of which we gave some account 
in our last number. Both treatises, however, may be advantageously 
read by those who are entering on the study of astronomy, indepen- 
dently of every other aid_or-illustration.. We sincerely hope that 
these little books may conspire with the other efforts of the same 
gentlemen, to diffuse a more general taste for the study of astronomy, 
particularly throughout our primary schools and academies. 
10. Catalogue of plants in the vicinity of Amherst College—This 
catalogue was prepared by Prof. Hitchcock, and published by the 
Junior Class of 1829, in Amherst College, for the benefit of botanica? 
students in that institution. It embraces all the indigenous and nat- 
uralized plants, that have been discovered within forty or fifty miles 
of Amherst, to which have been added such as are peculiar to the 
White Mountains and the sea coast of New England ; so that its util- 
ity may be shared by botanists situated in any part of the northern 
section of the United States. Its particular design, as declared in 
the preface, is, to facilitate the student’s examination of plants, by 
pointing him to those species, which he may expect to find in his dis- 
trict, and whose descriptions, therefore, he may ‘select in the Floras 
and Manuals of American plants ; to present him with an authority 
for each specimen, with the most important synonymes; and, in case 
of rare plants, to particularize the precise spot where it may be found. 
Exclusive of the plants peculiar to the White Mountains and the sea 
coast, it contains five hundred and thirty one genera, and — thou- 
sand four hundred and forty seven species, which occur within fifty
