that the movement of the nutritional fluids, under the 

 effects of such a power, is not dependent on the movement of 

 the heart. Because juices similarly assimilate, grow, and 

 form new parts throughout their life in plants, and because 

 at the same time there is no other power comparable to the 

 power of the heart movement, the movement of plant juices 

 should also be described under the special power. 



Therefore the following is asked: 



What is the nature of that power, and in 

 particular, is it identical with the commonly known 

 powers, or is it, as they think distinguished from 

 those and innate only to animals and growing plant 

 substances? If the latter is true, the next question 

 follows: of what general character is the effect of 

 this power and by what properties is it distinguished 

 from the general magnetic powers, indicating its 

 exceptional nature? 



In this competition, work from different countries was 

 submitted. Among the twenty-four submitted works a large 

 number were not worth serious consideration. Wolff reviewed 

 all these works and, based on his opinion, two works were 

 published: the article of J. F. Blumenbach (27), professor 

 of medical sciences in Gbttingen, 2 and that of K. F. Born, 

 doctor of medicine and surgery and ordinary lecturer at the 

 medical-surgical institute in Kronshtadt. 3 Wolff combined his 

 own article with these two articles, and they were printed 

 together in one manual; Wolff's work presented his opinion 

 about Blumenbach' s and Born's articles, but it mainly contained 

 the statement of his own ideas. 4 



The article by (Johann Friedrich) Blumenbach is entitled, 

 "Attempt to answer the competition question, for the third 

 time proposed by the Improvisator of the Academy of Science 

 in Petersburg: Uti nutritio aequalibus etc.?" 

 Born's article does not have a title, but was simply called 

 "Second article on the feeding power." 



The general topic of the manual appears on the title page as, 

 "Zwo Abhandlungen uber Nutritionskraft, welche von der 

 Kaiserlichen Academie der Wissenschaften in St. Petersberg 

 den Preis getheilt erhalten haben. Die erste von Herrn 

 Hofrath Blumenbach und zwote von Herrn Prof. Born. Nebst 

 einer f erneren Erlauterung eben derselben Materie . " Von 

 C. F. Wolff, der Akademie Mitglied, 1789.
