86 Notices of Institution Lectures. 



Agassiz make mention of the liberal manner in which the objects of his 

 researches had been entrusted to him by the proprietors of the dififerent 

 collections which he had visited throughout the country. 



For the information of the proprietors of local collections, we feel much 

 pleasure in stating, that the curator of the Bristol Institution has kindly 

 offered to take charge of any specimens which they may feel disposed to 

 exhibit to M. Agassiz during his visit in the spring. 



TIDE GUAGE. 



In consequence of the suggestions of Professor Whewel, a Tide Guage 

 was erected upon the Avon in 1833, by the Members of the Literary and 

 Philosophical Society, and has now been in operation upwards of twelve 

 months. The Guage is a self-registering one, constructed, with a few 

 alterations, after the model of that invented by Mr. Palmer, and fitted up 

 at the London Docks. 



The spot selected for the observation is at Hungroad, near the mouth of 

 the Avon, upon the estate of R. Bright, Esq. who has materially assisted 

 the object by much personal attention ; and is interesting as having been 

 selected no less than one hundred and sixty years ago for a similar pur- 

 pose, by Captain Stnrmy, whose observations are recorded in the third 

 volume of the Philosophical Transactions. 



Since the erection of the machine, the result of its observations have 

 been transmitted to and approved by M. Whewel, and a copy has also been 

 deposited in the Hydrographer's ofifice. Admiralty. We shall in future 

 publish quarterly reports of the register, commencing with Januarjf, 1835.
