184 Phenomena of the Cuba Hurricane. 
. These are results obtained by Mr. Pippineron, who has al- 
ready published his T'welfth Memoir, and who informs me that 
he is preparing another on this hurricane of the Charles Heddle. 
In his Eleventh Memoir, he has given an account of two storms, 
which were nearly contiguous, but on opposite sides of the equa- 
tor, and revolving in counter directions, ©) tj, each ac@ording to 
the law of rotation and progression of its own polar hemisphere.* 
Vertical Heicut or THE Storm Winp.—What is the general 
height or thickness of the storm, and by what means can this be 
approximately determined? These questions and their solution 
are: doubtless of some importance in their bearing on meteorolog- 
theories, and seem to deserve our attention. 
In nearly all great storms which are accompanied with rain, 
there appear two distinct classes of clouds, one of which, com- 
prising the storm-scuds in the active portion of the gale, has al- 
ready been noticed. Above this, is an extended stratum of stra- 
tus cloud, which is found moving with the general or local cur- 
rent of the lower atmosphere which overlies the storm. It covers 
not only the area of rain but often extends greatly beyond this 
limit, over a part of the dry portion of the storm, partly in a bro- 
ken or detached state. This stratus cloud is often concealed from 
ban Scar mimbns and scud. oe in the rainy pation: of the

ral are eee turning or rotation of storms in the southern hemis- 
phere i is in the negate <p tion to those in t “4 northern ; and he adduced cer- 
tain European storms as turning from 8. W. to W win - W., and says that most 
of the hy SE compared by him, in the southern hemisphere, are in the opposite 
direction, that is S. W., 8. E. ; but probably imei in dierent longtden, (Pogg- 
Ann, 1328, pp- 597, 598. )—Both these directions, however, are seen to be contrary 
to the true rotative direction in the storms thus refered to; as T am at a loss to 
know if he did not then consider the opposite veering of the winds, on opposite» 
sides of the barometric minima, to be evidence of two opposite and distinct rota- 
ions, 
he opposite rotation and polar progression in the storms of the two opposite 
consistent character. ‘This point was summarily alluded to in this Journal for 
October, 1833, vol. xxv, pages 121 and 128. In the last named instance, the com- 
plete i inversion of the storm-winds, as exhibited on the center-path of the storms 
in southern Australia, was referred to as conclusive evidence.
