Another objection to Mr. Redfield's theory of gyration is based upon the fact that in order to constitute his _storm_, to get the _gyration_, he has to include, at least, an equal amount, generally a great deal more, of _fair weather_. The N. W. wind, the "posterior, or dry side of the gale," as he calls it (in the foregoing extract), is a _fair weather wind_. It is _necessary_, however, to complete the supposed _circle_, and it is _pressed into the service_. The practical answer given to the question, "_what are storms?_" is, they are cyclones, part storm, so called, and _part fair weather_; that is, the stratus-cloud, the scud, the easterly wind, and rain or snow of day before yesterday, were the _wet side_, or front part of the storm, and the sunshine, clear sky, and N. W. wind of yesterday, to-day, and, perhaps, to-morrow, are the posterior or dry side. When a storm clears off from the N. W. it is not _over_, it is, perhaps, _just begun_; and, inasmuch as it storms again, very soon after the wind changes back from the N. W. to the southward, in winter, our weather then is pretty much all _storms_. The statement of this claim seems so absurd that it may appear like injustice to make it. But gyration can not be made out without it, and it is evident in the extract quoted above; in the claim that the winter northers of the Mexican Gulf are parts of passing storms; and clearly and unequivocally advanced as a distinct proposition, as follows: "1. The body of the gale usually comprises an area of rain or foul weather, together with another, and, perhaps equal, or greater, area of fair or bright weather." (Am. Jour. of Science, vol. xlii. p. 114.) Now, in the first place, we must distinguish between a storm and fair weather, before we can tell what the former is, and it is difficult to assent to a theory which explains what a S. E. storm of _twelve hours'_ continuance is, by including _two or three days of succeeding N. W. fair weather wind_, as a part of it. There is no proportionate relation as to _time_, nor any relation as to _qualities_, or the attending conditions of the atmosphere, nor any conceivable _connection_, except the hypothetical one of _gyration_, between the two winds. And, in the second place, it is true, and Mr. Redfield is well aware of the fact, that winds often blow for many days from the N. E., S. W., or N. W., without any preceding or succeeding winds to which they have any discoverable relation. If, therefore, truth would justify Mr. Redfield in including the fair weather wind, a difficulty would remain which his theory does not cover or explain.
