ROYAL SOCIETY OP GCTTINGEN. 



The Royal Society of Arts and Sciences of Gottingen has 

 offered a prize of .50 golden ducats, for the best Memoir on 

 the fallowing subject : " The difference of colour remarked 

 between the blood of the veins and that of the arteries 

 having induced an opinion among several of the learned, 

 that the same difference exists in the blood of the embryo 

 in an inver.se degree ; but as experience has never confirmed 

 this with respect to new-born infants, the society is de- 

 sirous that, by researches and direct experiments upon in- 

 fatUs born of healthy mothers, (either by the instant liga- 

 ture of the umbilical cord at its two extremuies, at the 

 moment of their birth, or in any other way,) it should be 

 determined if there really exists an inverse difterence in the 

 colour of the blood ; in what it consists ; what are the con- 

 stituent principles of the blood of the infant ; — keeping out 

 of the question the acid particles, which must;be mixed with 

 it by the contact of the atmosphere ?" 



The memoirs in answer to this question must be trans- 

 mitted to the society previous to September 1808. 



UNIVERSITY OF GOTTINGEN. 



The following question has been announced for the sub- 

 ject of a prize essay, by the University of Gottingen: 

 *' What is the influence of the acid and other kinds of gases 

 upon electricity produced by friction ? and what are the 

 relations of the other electrical phaenomena, such as attrac- 

 tions, repulsions, sparks, &c., with the principal gases ?" 

 This question has been announced for two successive years ; 

 but the memoirs not being satisfactory, it has been renewed 

 for the year 1809.
