amount of additional labor incurred by astronomical, photo- 

 metrical, and other observations, which arc partly undertaken 

 with the view to assist Mr. Ellery, the astronomer of the 

 colony, in his important and useful labors. • 



It only devolves upon me to add, that with two assistants 

 I am at present keeping this extensive system of observation 

 going, which certainly cannot be done without considerable 

 self-denial from the parties concerned therein. 



In conclusion, let mc express a hope that the Institution 

 we have called into existence may continue to flourish, and 

 that its labours may be replete with results of the highest 

 value to science and the happiness of mankind.

Note. — Since the time this paper was first read, the collection of instru- 

 ments of the Observatory has received some valuable additions, namely — a 

 self-registering anemometer, on Oesler's construction, was put up in one of the 

 upper rooms of the dwelling house, and will greatly add to the completeness 

 of the meteorological observations ; besides this, I may state that an ar- 

 rangement has been made to connect a clock in the telegraphic room with 

 the absolute and horary house, by electric currents, whereby signals are 

 given, rectifying the time of registration as well as greatly facilitating the 

 obtaining of simultaneous readings in the horary and absolute houses.
