156 YEAR-BOOK OF PACTS. 



the eyes to the temples, supporting the fabric from the lower part 

 of the shade, thus forming one large closed chamber for the eyes. 



The fineness of the fabric will be found to protect the wearer from 

 wind, dust,. and sun, but allows of sufficient ventilation to keep the 

 eyes perfectly cool ; and a lengthened opening at the top of the 

 shade (not observable when worn) provides for the escape of any heat 

 that may be engendered by violent exercise — the want of which is 

 felt in the ordinary shade. 



The occhiombra can be placed and removed with the same ease as 

 a pair of spectacles, and is so light as to be scarcely perceptible to the 

 wearer, being in weight about half-an- ounce. 



The fabric is sometimes doubled, to meet the requirements of those 

 with weak or inflamed eyes, but is sufficiently transparent, in all 

 cases, to enable the wearer to thread his' way through any crowd 

 with perfect comfort. 



The occhiombra will be found of great service in protecting from 

 wind and ashes those who travel by railroad. Travellers in India 

 and Egypt, and Alpine excursionists, will find it of inestimable 

 benefit — the first as a protection from sun and sand, and the latter 

 from sleet, wind, and the painful glare from the snow. It also re- 

 lieves the angler from wind 'and glare on the surface of the water ; 

 but it will be found of especial service to ladies, and those who visit 

 the sea-side, protecting them from excessive wind and light, render- 

 ing it unnecessary for the former to wear a veil, and thus allowing 

 free respiration of the pure sea air. 



The occhiombra does not in any way interfere with the wearing 

 of spectacles, and is manufactured in different colours, to meet the 

 tastes" of those who adopt it. 



This new eye-shade is sold by Messrs. Weiss and Sou, 02, Strand. 



NEW SPIROMETER. 



A NEW form of Spirometer has been exhibited to the British 

 Association, by Dr. Lewis. The novel principle of the machine is 

 the displacement of water by expired air, the amount of the latter 

 being equivalent to the former. A graduated scale attached to the 

 ride of the instrument indicates the amount expired during an ex- 

 periment.
