The Eev. T. E, E. Stebbing, F.E.S., Sec.L.S., exhibited:— 

 (1) a House-spider {Te(jenana sp.) with its cylindrical dwelling 

 in the coiled feather of an Indian fan. The fan which the spider 

 adapted to its purposes had been hanging up in a drawing-room at 

 Jerusalem. The spider, forwarded by Miss Eitzjohn to Miss Grace 

 Stebbing, reached England alive. And (2) a solid gnaur or 

 excrescence upon the root of Cvpressus macrocarpa^ sent for 

 exhibition by Mr. E. G. Smart, E.L.S., of Tunbridge Wells; it 

 was eleven inches in circumference. 



Prof. Peec'IVal remarked that such growths were commonly

 hypertrophy of the tissues ; it was not infrequent in Piiius, but 

 more usual on the stem than the root.

 animals, in the occurrence of the form of nuclear division know

 division.
