7. Albumen of the Eijg. — 100 parts of" liquid albumen, after 

 being coagulated, by exposure to air, became 15 parts ; and iw 

 vacuo 13.65. The dry substance was colourless, semi-trans- 

 parent, and it recovered the properties of boiled white of egg- 

 in absorbing water, which, however, it took up only to 68 parts 

 after four days' immersion, instead of the 86.33, which it had 

 lost. White of egg uncoagulated, dries without ceasing to be 

 transparent. It loses in air 85 per cent., and in vacuo 86.15. 

 On immersion in water it resumes its original viscid appear- 

 ance. — Ann. de Chim. et de Phys., xix. 32. 



Cure of a Palsy by a stroke of Lightning. — Mr. Samuel 

 Lefters, of the county of Carteret in North Carolina, had been 

 attacked with a palsy in the face, and particularly in the eyes. 

 While he was walking in his chamber, a thunder-stroke threw 

 him down senseless. At the end of 20 minutes he came to 

 himself; but he did not recover the entire use of his limbs till 

 the evening. Next day he found himself perfectly recovered ; 

 and he could now write without the use of spectacles. The 

 palsy did not return. 



Analysis of the Table-spar of Pargas, the Wollastonite of 

 Haiiy. By M. P. A. de Bonsdorff. — The colour of this table-spar 

 is a white, more or less pure ; it is traiislucid on the edges ; 

 its lustre is vitreous and moderate ; it is semi-hard, scratching 

 glass with difficulty ; under the hammer it splits into fine 

 flexible threads. Exposed to the blow-pipe, it melts on the 

 edges at a strong heat, affording a translucent glass, colourless 

 and brilliant. With borax, and the double phosphate of soda 

 and ammonia, it melts into a transparent glass ; and gives with 

 soda an opaque globule. With solution of cobalt, it presents 

 a blue colour, a property which does not seem to agree with 

 the nature of tremolite, which treated with the same solution, 

 exhibits usually a flesh colour. Its analysis afforded,

Analysis of the Meteoric Stone of Juvenas, by M. Laugier. — 

 Four analyses were made ; the first by means of acids ; the 

 second witli potash ; the third with nitric acid, to determine the 

 proportion of sulphur ; and the fourth by nitrate of barytes ; 

 with the view of ascertaining the proportion of potash which 

 M. Vauquclin had detected in this stone. Tiiese different ana-
