in a tomb near Thebes, and supposed to be of the 20th or 26th 

 Dynasty ; he also showed some fresh flowers of Ipomea purpureo- 

 candea. — A paper was read by Mr. E. M. Holmes, on Cinchona 

 Ledt/eriana as a species. The author expressed the opinion that 

 under the name of Cinchona Ledijeriana a number of varieties or 

 forms, and probably some hybrids of Cinchona Calimija are now 

 under cultivation in the British colonies. He believed that if 

 more attention were paid to the characters afforded by the Ijark of 

 the trees, taken in conjunction with the other botanical characters 

 of flower and fruit, these varieties and hybrids Avould be more 

 easily defined and recognised. He considers that the plant pub- 

 lished under the name of Cinchona Ledgeriana by Dr. Trimen was 

 probably referable to Weddell's Cinchona Calisaya var. pallida 

 as a horticultural form, for which the author proposed the name 

 Trimeniana. — Mr, E. T. Druery read a paper on a singular mode 

 of reproduction in Athyrium Filicc-fcemina var. clarissima. In a 

 previous paper the author had shown that prothallia bearing 

 antheridia and archegonia were developed on the apex of pear- 

 shaped bodies with the larger end downward, in the place usually 

 occupied by sori. In the present paper he brought forward evidence 

 to show that these pear-shaped bodies were not developed from 

 sporangia, but from a previous formation of thread-like bodies, a 

 few of which became thickened and developed into the pear-shaped 

 bodies previously mentioned, the others remaining starved and un- 

 developed.

 and J. H. Tompson, of Melbourne, Australia. — Mr. W. T. Tliisel- 

 ton Dyer exhibited — (1) Examples of leaves of Sagittaria nionte- 

 vidensis under different modes of cultivation ; the changes thus 

 induced as regards size and general facies being most remark- 

 able, so much so that they might be deemed widely separate 

 genera. The small leaves were from a plant raised from seeds 

 collected in Chili by Mr. J. Ball, and sent to Kew in 1883, and 

 grown in a pot half submerged in the Nympha'a tank. The 

 enormously large leaf and spike were those of a plant raised from 

 seeds ripened at Kew and sown in spring (1884). When strong 

 enough the plant was planted in a bed of muddy soil, kept 

 saturated by means of a pipe running from the bed to the yymjdia-a 

 tank. (2) A special and peculiar instrument called a " ladanis- 

 terion," from Crete, it being a kind of double rake with leathern 

 thongs instead of teeth, and used in the collecting of gum- 

 labdanum. — A paper by Mr. Alfred Tyler, " On the Growth of 

 Trees and Protoplasmic Continuity," was read.
