42 Slides of Acari from Mr. A. D. Michael. 



1 Slide „ Mr. F. Wood. 



Special thanks were voted to Mr. Michael for the present of the series of 

 type slides of Acari, which form a valuable addition to the cabinet of the 

 Club, and the following communication from Mr. Michael on the subject v^as 

 read by the Secretary : — 



"Herewith I hand you 42 slides of Oribatidae (all set in balsam). These 

 slides, when added to those which I have before given to the Club, will 

 form a type collection of all the Oribatidae hitherto recorded as British, 

 "with the exception of eight species, of which I have not been able to 

 obtain duplicates ; they also contain larvae and nymphs of many species. 



" I may remind members that the chitine of which these creatm-es are 

 composed is extraordinarily brittle, and that, consequently, the slides 

 require care in handling." 



A letter was also read from Miss Morrell, enclosing a photograph of the 

 late Mr. James Annett, and presenting the sum of £10 to the Club. The 

 special thanks of the meeting were voted to that lady for her valuable 

 donation. 



Announcements of Soirees by the Tower Hill Microscopical Society 

 and the Croydon Society, were made by the Secretary j and the co-operation 

 of the members was invited. 



Mr. Martinelli read a paper " On the Germination of a Seed." 



The President invited some remarks upon the paper, observing that 

 visitors present were not only at liberty to join in the discussions, but the 

 Club would be very pleased if they would do so. They were favoured that 

 evening by the presence of Dr. Fischer, of Sydney, and also of Mi-. Stephen 

 Adams, the Secretary of the Natal Microscopical Society. 



Dr. Fischer said that the subject before them had many aspects, but it 

 had been only treated chemically, and in order to the proper understanding 

 of the subject, it needed to be regarded physiologically also. He had also 

 expected to hear something more of the tubers referred to, and should like 

 to know why they had not developed. 



Mr. J. T. Powell said he had been a good deal interested in the subject, bnt 

 thought it almost necessary to supply a little moi-e information on some 

 points connected with it. The movements he thought resulted from the 

 successive development of the different parts. The first part which began 

 to grow was the radicle, and that grew downwards ; and the next important 

 growth was that of the stalks of the cotyledons, which had a great in- 

 fluence on the growth of the plumule, in the case of those which brought
