quired to be deposited in the office previously to the granting of a 
patent for any machine ; and although these, when simple, may be 
made in Washington from a good drawing, it will always be more 
satisfactory to have them sent by the applicant. When drawings 
are forwarded, they should be signed -by the applicant, and be wit- 
nessed by two persons. 
All letters making inquiries respecting patents must be post paid ; 
and where examinations in the Patent Office or elsewhere, or writ- 
ten opinions, are required, a fee of five dollars will be expected. 
The charge for specifications and drawings must depend upon their 
complexity, but will be moderate.

by Georce Jones, A. M., Chaplain U. S. Navy: Author of 
Sketches of Naval Life. New York: Van Nostrand & Dwight, 
1836: pp. 388, large 12mo.—This very instructive and beautiful

a share of his own enthusiasm. 
In the present instance, the scene is laid in countries long ven- 
erable and venerated, as the cradle of knowledge, of religion, of arts, 
of dominion : we cannot know too much of Egypt and Palestine, of 
the Nile, of the Pyramids, and of the Holy City. 
In the case especially of the latter, Mr. Jones has been happy in 
separating truth from error, and we are strongly impressed with the 
conviction that the most important localities of Jerusalem are now 
well ascertained, and are clearly indicated by him. 
In support of the authority of Mr. Jones’ book, there is at present 
a happy and very unexpected coincidence between the facts which 
he has stated, and very satisfactory evidence derived from another 
source. We allude to the valuable lectures of Mr. Catherwood, 
accompanied by fine illustrations from his own pencil, industriously 
employed, during a course of four years in Palestine, Syria and 
Egypt, to exhibit the wonderful antiquities and scenery of those
