remarks by reference to diagrams, and mentioning some very 
interesting experiments with tadpoles, frogs, &c. He regretted 
that since he had undertaken to read the paper he had been so 
much occupied that he had not had time to prepare it in the 
manner he intended, and he feared that what he presented to the 
members only gave them a disconnected idea of the subject. 
Dr. Carpenter thought that Dr. Greenfield had expressed him- 
self so ably that he had left no hole by which he could be pulled 
to pieces. He had expressed himself very ably on a difficult 
subject, but one which must commend itself to the Microscopical 
Society. He then referred to the simplicity observable in Nature’s 
-works as seen in the structure of the capillaries, whether in animal 
or vegetable forms of existence. In those creatures which had no 
vessels they saw a budding process, which Dr. Greenfield had 
described, and which was very interesting to notice. - Dr. Carpenter 
also referred to the first establishment of circulation in some 
animals as being more in connexion with the lacteals than the 
capillaries, and independently of heart or brain. 
Mr. Asupy also made a few remarks on the lecture. 
Dr. GREENFIELD haying replied,_a cordial vote of thanks was 
passed to him for his very interesting lecture, and the President 
‘intimated that it had given the members great satisfaction, and 
that they would be very pleased to hear Dr. Greenfield again. 
Mr. A. D. Taynor, who exhibited some honey-comb with queen 
bees and workers, said he had asked a friend of his to get him 
some queen bees, and he had thought of him during the winter, . 
and furnished those now produced. The bees appeared to be in 
situ with the portion of the comb in which they had been found 
dead. 
Dr. Carpenter asked in the event of a queen-bee dying, how 
the vacancy was filled up. 
Mr. Taynor said he believed that numerous queens were born, 
but only one was chosen. 
_ Mr. Berney said that during the reign of the old queen-bee, the 
younger queens in the hive were imprisoned ; but if the old queen 
died one of the younger ones were let loose to be the future queen.
