the building in negen!'S Park, it has been supposed
the term is formed of BIr, dis, twice, and Drama. But
it is to be observed, that, if several paintings of the
same kind were exhibited, each painting would constitute
a IJiorama. To the first meaning, however,
it must be confined when only one scene is presented,
as in an ingenious toy made at Brussels.

several distinct paintings (seen through a magnifying
glass) of different places in each quarter of the world

I\Iyri-orama. (Sec I\IrRIAD.)'i' The 1\1yriorama consists
of sections or fragments of'landscapes on 24 cards,
so ingeniously contrived, that any two or more
placed together will form a pleasing view. ,The
variations which may be produccd by these 24
cards, amount to the almost incredible nnmber of
620,448,401,733,239,439,360,000, the magnitude of
'i:hieh cannot be better illustrated than by the following
observations: - Supposing it possible to effect
one of these changes every minute, night
and day, to produce them all it would require
1,180,457,385,337,213,545 years, 75. days; that is
to say, if all the inhabitants of this globe (computing
them at 1,000,000,000, of which, according
to common calculation, they fall considerably short)
were employed in the task, it would take them
1,180,457,385 years to complete it: which is more
than 196,742 times the period which has clapsed since
the Creation of the 'VorJd." Supposing the space
occupied in length by each of these landscapes
(when the whole of the cards arc employed) to be
a yard (and it is nearly donble), they "'ould, by
being placed one after the other, cover the length
of 352,527,500,984,795,136,000 miles, that is,
