CALENDARIAL MEMORANDA FOR JUNE.

hensive idea of either measurable or immeasurable space ; he is so 
bound down to his mother Earth, that he can neither divest himself 
of an impression of her fixedness, or that the apparent motion of the 
sun and other heavenly bodies is not real 5 and far less could he have 
any clear ideas of the convolved and visibly contrary motions of the 
other planets. 
Mr. M. has endeavoured, and we think successfully, to clear away 
those clouds which obscure the real positions and motions of the 
planetary worlds from the ken of a young pupil, by showing how to 
reconcile “ the real motions with the apparent ones, which are, gene¬ 
rally speaking, the very reverse of the real ones : and unless a beginner 
shall be shown clearly, at the commencement of this science, why he 
should distrust his senses , he feels some difficulty in getting rid of 
scepticism afterwards; and although he may assent to the words of 
the true statement, he continues to have doubts concerning them.” 
It is by detaching, as it were, the student from his terraqueous abode, 
and placing him high in the ethereal vault, even above the sun itself, 
that he may see all the revolving bodies of the solar system at a 
glance, which can alone enable him to comprehend the “ mighty 
maze.” 
It is by this extra-mundane contemplation of the constitution of 
the heavens, that the author has infused into this little elementary 
work, and with the most perfect plainness, some of the most profound 
researches and discoveries of the science of astronomy; on which 
account it deserves to be read and studied by every one wishing to 
acquire a competent knowledge of this interesting science. 
CALENDARIAL MEMORANDA FOR JUNE. 
When an editor of a monthly periodical has once gone the circuit 
of the months with calendarial remarks, it is usual, and quite natural 
for him, when he arrives at the point where he began, to refer his 
readers to the corresponding period of the bygone year for seasonal 
memoranda. To a reader who keeps the numbers constantly at his 
elbow, this may be no great trouble; but many would find the refer¬ 
ence inconvenient. We shall, therefore, continue the memoranda, but 
in a somewhat condensed form, as we consider a naked hint is 
useful, and all that is wanted by a reader constantly engaged in the 
business.
