bryonary cells, with this constant difference, that they are themselves 

 spontaneously formed, and become the determining cause of the evo- 

 lution of the latter. 



"2. As to the development of the tail, or the vibratile cilia of the 

 spermatozoa of algae and of animals, and the movements they present, 

 these are not more astonishing than the formation of vibratile cilia 

 on the surface of epithelial cells of mucous membrane, and both are, 

 without doubt, of the same, and as yet unknown, nature. But the 

 movements they exhibit are not of themselves sufficient to charac- 

 terize spermatozoa as animals, no more than the carrying about of 

 an epithelial cell, or of a spore of fucus by the agency of cilia can 

 constitute either of those an animal ; in fine, they are no more ani- 

 mals than are embryonic cells. 



" 3. It being once recognised that an ovule is formed by the male 

 apparatus analogous to that produced by the female, and presenting 

 an identity with the latter in its evolution, two series of ovules may 

 be naturally formed : — 



'• A. — Of male ovules. 



"1. Those of animals (parent zoospermic utricles). 



'• 2. Those of cryptogamic plants (antheridia, or cells fulfilling their 

 purpose in the Ulvacece and other cryptogamia) . 



" 3. Those of phanerogamous plants (parent-cells of pollen). 



" B. — Of female ovules, or ovules strictly so called. 



** 1. Those of animals (ova). 



" 2. Those of cryptogamic plants (spores, some zoospores, spo- 

 rules). 



" 3. Those of phanerogamic plants (vegetable embryonary sac). 



" All ovules or ova are constituted essentially of a vitellus with its 

 germinal vesicle and vitelline membrane. But in the male ovules 

 the division of the vitellus is a primitive phsenomenon, spontaneous, 

 and always limited to the formation of spermatozoa — the true em- 

 bryonary cells of the male, which have the property of determining 

 in the female ovule the same phsenomenon (self-division) which 

 has given them birth, and which proceeds in the latter to the evolu- 

 tion of the embryo. The female ovules, on the contrary, form the 

 second series of organs, the vitellus of which, in order to become 

 divided in its turn, and to form the primary cells of the embryo, 

 needs the concourse of the spontaneously developed products of the 

 male vitellus." — Comptes Rendus. 



On the Gum Kino of the Tenasserim Provinces* 

 By the Rev. F. Mason. 



In a valuable article by Dr. Royle on Gum Kino, reprinted in the 

 Journal of the Agricultural and Horticultural Society of India, which 

 ostensibly enumerates all the various regions from which it has been 

 imported into England, there is no mention of this article being im- 

 ported from this coast. Yet long before Dr. Royle compiled that 

 communication, more than one consignment had been made by par- 

 ties in Maulmain to houses in London of gum kino to the amount 

 of a thousand pounds. 



It was brought to Maulmain by an English merchant from the
