Dr. Wallicb, V.P.L.S., read the following extract of a letter from 

 Prof. Lehmann, dated Hamburgh, 14th December, 1849 : — " I write 

 to inform you that a work has just appeared, namely Proceedings of 

 the Fifth Meeting of Scandinavian Naturalists held at Copenhagen 

 1847. Copenhagen, 1849. 8vo. There is in it a very remarkable paper 

 by Liebmann, entitled ' A few words concerning the Impregnation of 

 Cycadece,' p. 501 seq. It appears, according to this paper, that in 

 that family ripe and vegetative fruits may be produced, without the 

 process of impregnation. A female plant in the Botanic Garden at 

 Copenhagen (males do not exist in Europe) produced seeds which 

 have germinated I Liebmann made the same observation in Mexico."
