BROWNING'S ANEROIDS. 



"The Aneroid is the best Weather-Class /«rtrf'^."— Colonel Sir HENRY James's "Treatise on Meteorological 

 Instruments." 



Mr. Belville, of the Royal Observatory, Greenwich, in giving the meteorological result of a tour in Wales, 

 obtained by means of an Aneroid, says : — 



" It was a delightful companion, and highly useful, its indications preventing many an excursion which would have ended 

 in disappointment." 



From its extreme sensitiveness, great portability, non-liability to derangement, and elegant appearance, the 

 Aneroid is rapidly superseding the Mercurial Barometer for all general purposes.
