probable, that Zakhar Zakharovich van der Hulst is the author 

 of a dissertation cited in the text on page 7: the difference 

 of names (Zakharii and Arnold) does not speak against this 

 supposition, as both names could belong to the same person.

(7) Speaking about the collection of anatomical prepara- 

 tions, present in Kunstkamera N. G. Kurganov noticed, that

in the treatise "Opisanie chelovecheskogo telo" (Description 

 of human body) , where they compose its fourth part — "About 

 the development of the embryo. Parts, formed in semen" and 

 the fifth part "the formation of hard parts". The treatise 

 was published two years before the death of the philosopher, 

 in 1648. In addition, with the birth conception of living 

 substances, "which are produced by semen", Dekart also
