the use of these interminable technicalities to the world at large? Do they
enlighten the rheumatic as to how many coats they may put on, for the
Midsummer days of this variable climate? Do their barometers tell us when
to take an umbrella, or when to leave it at home? No. Who, we further ask,
knows _how_ hot it is when the mercury stands at 120°, or how cold it is
when opposite 32° of Fahrenheit? Only the initiated, a class of persons
that can generally stand fire like salamanders, or make themselves
comfortable in an ice-house.

Deeply impressed with the importance of the subject, PUNCH has invented a
new thermometer, which _may_ be understood by the "people" whom he
addresses--the unlearned in caloric--the ignorant of the principles of
expansion and dilatation. Everybody can tell, without a thermometer, if it
be a coat colder or a cotton waistcoat warmer than usual when he is _out_.
But at home! Ah, there's the rub! There it has been impossible to ascertain
how to face the storm, or to turn one's back upon the sunshine, till
to-day. PUNCH'S thermometer decides the question, and here we give a
diagram of it. Owing a stern and solemn duty to the public, PUNCH has
indignantly spurned the offers of the British Association to join in their
mummeries at Plymouth--to appear at their dinners for the debasement of
science. No; here in his own pages, and in them only, doth he propound his
invention. But he is not exclusive; having published his wonderful
invention, he invites the makers to copy his plan. Mr. Murphy is already
busily arranging his Almanac for 1842, by means of a PUNCH thermometer,
made by Carey and Co.
