PHILOSOPHICAL, CHEMICAL, AND SCIENTIFIC MISCELLANIES. 



Eviii)oralion. — Ftom havinjj attentively 

 consi<lcied the theory of evaporation, Mr. ^ 

 Trcdgolfl has been led to consider the 

 annexed formulic as correct. Let T=thc 

 general temperature, t= temperature of 

 evaporating surface at its ultimate depres- 

 sion, \v=\veight of vai)our in grains, that 

 would saturate a cubic foot of air at the 

 t€ni])erature t ; a=evaporation per minute 

 from a surface of one foot when w=l, 

 f=height of the barometer ; e=evaporatioii 

 in grains that produces a depression of one 

 degree of temperature; x=the tempera- 

 ture of the point of depression. 



w=5600 (^-^ - 550?^) and 

 5600 a C -; — - — ^ = E or the 



U50+t iM+\y 



evaporation of a surface one foot square in 

 grains per minute. As t is only the tem- 

 perature of the evaporating surface, tiic 



general temperature will be T=t . — 



Taylor' s Jo urnal. 



Fossih. — From the last memoirs of the 

 Geological Society we find that a stratum 

 •containing a number of fossil trees has 

 been exposed by the action of the sea on 

 the east and west sides of the town of 

 Cromer, in Norfolk. This stratum is com- 

 posed of lamiine of clay, sand, and vege- 

 table matter, and is about four feet in thick- 

 ness ; in it the trunks were found standing 

 as thickly as is usual in woods, the stumps 

 being firmly rooted in what appears to be 

 the soil in wliich they grew. They are in- 

 variably broken off above u foot and a half 

 from the base. "The stem and branches 

 lie scattered horizontally, and among them 

 are thin layers of decomposed leaves, but 

 no fruit or seed vessels. The species of 

 timber appear to be chiefly of the pine 

 tree, with occasional specimens of elm and 

 oak ; they are flattened by the pressiu'e of 

 the overlying alluvial strata. Also in the 

 mouth of the Char, in Dorsetshire, there 

 have recently been noticed traces of a sub- 

 marine forest. Upon a flat of some extent, 

 stretching into the sea in front of the beach, 

 only visible at low water, and composed of 

 lias, patches of a blue clay show them- 

 selves, imbedding pieces of blackened wood 

 lying horizontally, similar in appearance to 

 those usually met with in sub-marine 

 forests ; some of tliem are large, but the 

 greater number must have been derived 

 from small trees ; mixed with these are a 

 feu' hazel-nuts, and abundant remains of 

 plants — chiefl}' such as are found in marshy 

 grounds. 



Meteorites. — From Dr. Chladni's cata- 

 logue of meteorites, inserted in the last 

 number of the Philosophical Magazine, it 

 appears that the first stone, of which the 



M.M. New Series — Vol. 1. No. 3. 



time of the fall can be indicated with any 

 degree of certainty, fell about 14-78 B.C., 

 in Crete, on the Cyheline mountain, was 

 considered as the symbol of Cybele, and was 

 that with wliich Pythagoras was initiated 

 into the mysteries of tlie Ida;i Dactj'Ii. 

 The only m<uis of iron containing nickel, 

 and crystallized in octahedrons, whose fall 

 may be considered as historically proved, is 

 that which fell near Ilradschina, in the pro- 

 viwc of Agram, in 1751. 



Longevity. — The following instances of 

 longevity are well authenticated, and are 

 curious exceptions to the general law of 

 human life.
