to that of other insects, composed of an orange-coloured yolk, formed 

 of yellow nucleated cells, surrounded by a very small quantity of 

 transparent vitelline fluid, and containing a very large germinal 

 vesicle with a distinct macula or nucleus. On the 2nd of December 

 the females were again seen to produce living young, and Mr. New- 

 port describes the process of parturition which he then observed. 

 These observations confirm the statements of former naturalists on 

 both the points inquired into, and negative the presumption raised 

 with reference to the capsular character of the egg by proving it to 

 possess all the characters of a true ovum.

 Edward Forster, Esq., V.P., in the Chair. 



Mr. Ward, F.L.S., exhibited specimens of the dried plant and fruit 

 of Uncaria procumbens, Burchell, from South Africa ; and also a por- 

 tion of the stipes of a fern from New Plymouth, New Zealand, pro- 

 bably belonging to Pteris esculenta, Sol., measuring several feet in 

 length. Mr. Carrington, from whom the latter specimen was ob- 

 tained, stated that the species of fern from which it was obtained 

 grows, in the neighbourhood of the coast, to the height of five feet, 

 in masses of from six to seven feet diameter, so strong and dense 

 as to be capable, if a cover were thrown over it, of sustaining the 

 weight of a man. On the margin of the bushland it attains a height 

 of twenty-one feet, and Mr. Carrington has observed it on the banks 

 of a river, when interlaced and matted together, to measure thirty 

 feet.
