Photographs of Messrs Hammond, Nelson, Priest, and Tinney were 

 also presented for the album ; and a quantity of Pollen of Cedar of 

 Lebanon was sent for distribution by Mr. Priest. " 

 The President called special attention to the valuable donation sent by 

 Mr. Cole. 

 A vote of thanks to the various donors was carried unanimously. 

 Mr. T. C. White read a paper upon the Fly Fungus (Empusa muscat), in 

 which he described its appearance and peculiarities, and illustrated the 

 subject by a specimen exhibited under the microscope. 



Mr. W. W. Eeeves suggested that Mr. White might have carried the 

 subject further with greater advantage, for if they wished to follow up the 

 growth of this fungus they must not be content merely to watch it as 

 found upon dead flies, this being only half its history. Let them drop the 

 fly into water, and then see what would take place. In a short time they 

 would see the fungus grow out and develop in a very beautiful manner. It 

 never fully developed upon a window pane for want of sufficient moisture, 

 but if this were supplied much more could be seen of its history. Very 

 little was known about it, but if any one wanted to become better acquainted 

 with it, by placing a fly thus attacked in a little water its further growth 

 might be readily studied. Like many of this class of fungi it assumed 

 different forms under different circumstances. It might be that the fly got 

 into a diseased state, and settled upon the moist window pane — for it was 

 only to be observed in damp weather. In the fifth volume of the " Quarterly 

 Journal of Microscopical Science," p. 154, some account of it would be found ; 

 and in vol. 3, p. 55, of the early Transactions of the Microscopical Society, 

 it was described and figured by Mr. Cornelius Varley. Mr. Eeeves added 

 that the f ungas was not confined to the house-fly — it was found also on the 

 blow-fly and several other insects. 



A vote of thanks to Mr. White was duly carried.
