from the perpendicular p, and continuing to rise, described 

 the diagonal *, c, parallel with g, e; now e,f, being always 

 parallel with p, the deviation from p was always equal, as well 

 upon the plate as upon the medal. 



This improvement being, as I have no doubt you will im- 

 mediately perceive, at once efficient and correct, I have pro- 

 cured my son a patent for it; and he is now constructing an 

 apparatus for performing the process upon busts and statuary, 

 and will, I expect, be able to produce a miniature representa- 

 tion of either, in which the resemblance will be faithfully pre- 

 served. I am, my dear Sir David,

ROYAL SOCIETY. 



Feb. 14, 1833.' — r I ^HE following announcement was made from 

 J- the Chair :— 



" His Royal Highness the President has received from Professor 

 Gauss the abstract of a paper read by him at the meeting of the Royal 

 Society at Gottingen, on the 15th of December last, entitled ' Inten- 

 sitas vis magnetic^ terrestris ad memurom absolutam revocata." Mr. 

 Gauss's views possessing considerable interest, His Royal Highness 

 is desirous that they should be made known to the Fellows of the 

 Royal Society ; but as the original paper will not be printed for many 

 months, and the abstract which appeared in the Gbttingisehe gelehrte 

 Anzeigen is in a language not generally understood in this coun- 

 try, His Royal Highness has requested your Foreign Secretary to 

 translate it ; and 1 am commanded to desire your Secretary to read 

 the same to the present meeting. 



" In deviating thus far from the usual routine of the business of 

 the Royal Society, His Royal Highness is actuated by a wish to pro- 

 mote the reciprocal and early communication of new and important 

 discoveries and views in science, between our own and the other So- 

 cieties of Europe, devoted, like this, to ' the improvement of natural 

 knowledge' 



" Communications of this nature, however, cannot of course be 

 admitted into your Transactions • but the publication, from time to 

 time, of your Proceedings, affords a happy means of giving them 

 general circulation ; and thus the rapid propagation of much valuable 

 information will be effected, which otherwise, if not absolutely lost to 

 us, would, at least, long remain unknown to the British scientific 

 public."
