suspended in tlie tube provided for their protection, and that they had 

 been carefully marked and measured. Since the last meeting observa- 

 tions have been made at intervals on the lengths of the wires, and these 

 have been carefully recorded. It cannot be said that there has been any 

 perceptible lengthening of the vrires within the last year. 



Some improvements have been made as to caulking the joints of the 

 protecting tube in order to avoid disturbance of the wires by currents of 

 air. 



A set of drawings, showing the mode of suspension of the wires, 

 the marks that have been put upon them, the arrangements of the 

 cathetometer, &c., in such a way as may be useful for reference at any 

 future time, is nearly ready, and will be published in next year's Report.
