 especially for the Board of Trade and Royal Life 

 Boat Institution, to be fixed at all the principal

fig. 170. Price, 5 5s. 



This Barometer consists of a tube with very large bore, and an 

 accurate Thermometer, mounted in a solid oak frame, firmly screwed 

 together, with scales and figures, &c., permanently engraved on Porce- 

 lain, by Negretti and Zambra's Patent process, the Vernier reading to 

 100-ths of an inch. It is strongly recommended as a good, sound 

 working instrument, admirably adapted for use in Public Institutions. 



Extract from, Admiral Fiti-Rc^fs Reports of the Meteorologio Office 

 of the Board of Trade, 1864 : 



"In my last Report, I stated how highly the Board of Trade 

 ' Fishery ' Barometers have been valued on the coasts. They are now 

 eighty in all, specially lent, under due control and care. Two only of 

 this number have become slightly defective, and have been exchanged . 

 Not one has been injured in carriage, singular to say, between Cornwall 

 and the Shetland Isles, Ireland and Yorkshire. It may be more readily 

 estimated mentally than accurately proved, to what extent these simple 

 instruments (all reliably madef and tested) have already been the means 

 of saving life and property. Explanatory manuals and blank forms for 

 diagrams have been extensively circulated among the coasters and 

 fishermen, who are all, now, much influenced by, and very thankful for, 

 the benefits of this act of their Government. Many are the local in- 

 stances of similar beneficence by individuals especially the Duke of 

 Northumberland, who has placed no less than fourteen barometers." 



Messrs. Negretti and Zambra would specially caution the 

 Public against purchasing cheap and worthless imitations of 

 Admiral Fitz-B-oy's Barometers as leading to disappointment. 

 Full details both as to the construction and use'of the true Fitz-Roy 

 instrument will be found in Negretti and Zambra's Barometer 

 Manual, compiled by Admiral Fitz-Roy for the Board of Trade ;
