A speciality of the firm consists in their thermometers for all 

 kinds of purposes, of which a large^ assortment is being exhibited. 

 In the manufacture of this class of thermometers, special weight is 

 attached to greatest possible distinctness and durability. In order 

 that these two conditions may be satisfied a departure w r as made from 

 the usual form of sealed thermometers consisting of sealed capillary tube 

 and scale encased in the outer tube, and the scale of the new thermometer 

 w r as made in the shape of a box. This construction admits of the 

 dimensions of the scale being made much larger than is possible 

 w r ith the usual type. This again renders it possible to use much thicker 

 capillary tubes of prismatic section. A thick column of mercury is 

 used and this again appears magnified several times by the action of 

 the glass. These broad ribbons of mercury, which are visible from a 

 distance, in conjunction with the deep divisions and large figures, impart 

 to these instruments a distinctness which has not been attained elsewhere. 

 The exhibits will bear out this assertion. This mode of construction has 

 the further advantage of admitting of a much more solid form of
