it was evaluated as a remarkable work in the book of 

 I. Bezeke, published in 1797 (see p. 114) and in the dis- 

 sertation L. Tredern (1808) (see Chapter 11) (87) . 



(25) Apparently, in the declaration of biological 

 works by the Academy of Science for a prize, Wolff showed 

 initiatives also early. Thus, in 1779 the academy declared 

 a competition for a prize on the question about reproduction 

 of cryptogamous plants. This theme of competitive work 



was written in expressions which a great probability impel 

 to consider Wolff the author of this question: "Theoriam 

 generationis et fructificationis plantarum cryptogamicarum 

 Linnaei dare etc...." (gives the theory of development and 

 fruiting of cryptogamous plants, by system of Linnae, plants 

 and so on) . 



In 1783, this prize was awarded to a professor in 

 Leipzig, log. Gedvig for the work under the title "Theoria 

 generationis et fructificationis plantarum cryptogamicarum 

 Lennaei, mere propriis observationibus et experimentis 

 superstructa dessertatio, quae praemio ab. Academia imp. 

 Petropol. pro Anno MDCCLXXXIII proposito ornata est" (105). 



(26) It is necessary to notice, that the embryological 

 problems have interested Petersburg Academy of Science before 

 the arrival of Wolff. It is possible to judge this, in 

 particular, by the published collection in 1756, which is 

 composed of two works (dissertations) , and sent to the 

 competition announced by the academy. The question, put by 

 the academy, touched upon the possible influence of the 

 impression, felt by the pregnant woman, on the developing 

 fetus. One of the mentioned works belonged to a professor 



at Leipzig University C. Ch. Krauze*, and another — to a 

 member of Petersburg Academy of Science, I. G. Rederer. 

 In lively controversy on this theme Byuffon participated. 

 He energetically objected to preformists, who according to 

 their views, the embryo is proved to be similar with the 

 parents under the influence of imagination of the mother.
