156 PROCEEDINGS OF [Feb. 



frequent use of the same numbers for different words might be simplified, as it is 

 divided into different classes, which use tlie 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 iu 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. 



1 feel thankful to you for the assurance of friendly feeling manifested towards 

 we, while in Wa.shinglon, 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 Holquine. Tliey 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 Holquino to resemble in physical properties as well as 

 chemical composition, tliose 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.

Sir: Permit me to acknowledge the receipt of your letter of the 11th instant, 

 informing me of the honor of having been enrolled as n 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 now meet the approba. 

 tion and sn pporl of the Government, and the scientific men of the District of Colum- 

 bia. It gives mo great pleasure to speak of Thomas Law; he was an enthusiast 

 in the cause of science, the arts, agriculture and manufactures, ajid 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.
