[Feb. 
frequent use of the same numbers for different words might be simplified, as it is 
divided into different classes, which use the same numerators for different words 
and sentences, which doubtless must create confusion. 
I am engaged compiling one, for use either on land or afloat, which will contain all 
required words or phrases used in daily business or political transactions, by which 
I will be enabled to telegraph any communication. 
The above are some of the advantages which my system of telegraph will have, 
and I avail myself of the present opportunity to give the outline of my vocabulary 
above mentioned. 
I feel thankful to you for the assurance of friendly feeling manifested towards 
me, while in Washington, and solicit your aid in my behalf to introduce my inven¬ 
tion to the notice of the “National Institution,” the opinion of which I am desir¬ 
ous to obtain; and being a native born American, I feel a national pride in having 
the honor to submit the above for consideration before so laudable an Institution. 
I am, sir, with great respect, your most obedient servant, 
HENRY J. ROGERS.

The ores, &c., contained in the boxes alluded to above, are principally, if not 
entirely, from the district of Ilolquine. They will be found interesting, as portray¬ 
ing the character of the mineral deposits of that region, as also of the rocks which 
occur in connection with the ores. 
Some of the quartz specimens, you will remark, are very curious. I have found 
the quartz of the veins in Holquine to resemble in physical properties as well as 
chemical composition, those varieties of opals which occur in the tertiary forma¬ 
tions of the environs of Paris. 
Believe in the consideration with which I have the honor to be, most respectfully, 
yours, &c., 
THOMAS G. CLEMSON.

Sjr : Permit me to acknowledge the receipt of your letter of the 11th instant, 
informing me of the honor of having been enrolled as a corresponding member of 
the National Institution, established at Washington for the promotion of science. 
I beg that you will have the goodness to convey my thanks to the members for this 
memento of their friendship and recognition of past services in the cause which 
has been so honorably revived at the seat of Government; and I most sincerely 
hope that all the objects which engaged the attention of Thomas Law, Esq., and 
myself, in 1816, in establishing the Columbian Institute, will wow meet the approba¬ 
tion and support of the Government, and the scientific men of the District of Colum¬ 
bia. It gives me great pleasure to speak of Thomas Law; he was an enthusiast 
in the cause of science, the arts, agriculture and manufactures, and no one had the 
prosperity of the city of Washington more at heart. 
I have the honor to subscribe myself, as your obedient servant, 
E. CUTBUSH
