6. Adulterations of various Substances used in Medicine and the 
Aris, with the means of detecting them; by Lewis C. Beck, M. D. 
New York, 8. S. & W. Wood, 1846. 12mo, pp. 332.—Following an 
alphabetical arrangement, Dr. Beck has presented in the present vol- 
ume much valuable information on all the common articles of com- 
merce and medicine which are known to be adulterated, as well as on 
many which are more rare. He has also pointed out the mode of de- 
tecting the adulterations by the application of proper chemical tests. 
The practical usefulness of this volume sufficiently recommends it. 
7. Observations in Natural History, with an Introduction on Habits 
of Observing as connected with the wr of that Science, &c. &c.; 
by the Rev. Leonarp Jenyns, M. A., F. L. S., etc., Vicar of Swaff- 
ham Bulbeck. London, J. Van Voorst, 1846. 12mo. pp. 440.—This 
scrap book is made up in a diary form, of the notes of interesting facts 
in Natural History observed by the worthy vicar and collector during 
the past twenty years. They embrace a great variety of subjects, and 
are written in the same flowing easy style which made White’s Selborne 
one of the favorite companions of our’youthful days. The volume is 
introduced by a chapter on habits of observation, and the value of such 
habits is well enforced by the silent example of the Rev. Jenyns, whose 
intervals of parochial duty have been filled with the varied een 
which nature always awards to her votaries. This volume is closed b 
a calendar of periodic phenomena in natural history, with a chapter on 
the importance of such registers.
