j The letters C, Q, X and Y are rejected, the first throe as superfluous, 



■^ and the Y on account of its unsettled power in English as well as in 

 other languages. Y and C are used in their inverted forms in which there 

 does not appear to be any danger of misunderstanding, on which ac- 

 count they and the others are rejected in their ordinary forms. The 

 sound of u in tuhe, tisage ; iew, in view, Sfc. is supplied by _;m. 



The diphthongs oi and oy as in toil and cloy will, of course, be ex- 

 pressed by oi, and ou and ow as in foul and fowl by au, according to the 

 analogy of the German. 



The combinations s/j, th, (as in tlie) wh and zh and their analogues 

 are retained or introduced, because their force is well ascertained and 

 easily understood, and it is not, in my opinion, desirable to burthen the 

 alphabet with any thing that can be spared. JS'g would have been 

 treated in the same way, had it not been for such combinations as j^7i^er, 

 which it might be inadvisable to write fingger, in consequence of the 

 danger of mistakes in the pronunciation. 



The formation of new characters by inverting those in common use 

 (first suggested by Etcing, I believe,) seems to me equally convenient 

 for the learner and for the printer. At the suggestion of Prof. Halde- 

 man, I substitute 3 (the numeral) (inverted) for 3i and 1 for the short 

 sound of I. I have also used o and A in accordance with his system 

 of general Phonography, of which I propose in my next article to com- 

 municate the sketch with which the author has so kindly favored me, 

 as it so ably illustrates my own views upon this subject, in which I 

 have been confirmed by the authority of a scholar who shows himself 

 so perfectly familiar with the subject. I cannot here forbear the expres- 

 sion of the hope, that the Am. Philosophical Society, to w'hich Prof. 

 Haldeman has communicated his system at length, will speedily favor 

 us with its publication. 



IMETEOROLOGY, NO. III. 



BY PROF. JACOBS, OF PENNSYLVANIA. COLLEGE. 



What is the physical cause of these phenomena ? 



Having stated some facts in IMeteorology, and traced what is presu- 

 med to be the law by which they are governed, it now remains to as- 

 sign, if possible, their physical cause. 



1. The remarkable coincidence between the periods of the lunar 

 changes and those of the weather at once compels ns to inquire, what 

 agency the moon may have in the production of the latter changes. 

 The necessity becomes tlie more imperative, as no other class of physi-
