condenser would, no doubt, prove a very great advantage to those 

 who were studying Hving organisms. 



The thanks of the Chib were voted to Mr. Swift for his exhibit. 



Mr. E. G. Wheler's notes on a " Remarkable Stigmatic Organ in 

 the nymph of Ornithodoros megnini " and on " Ixodes tenuirostris " 

 were read by Mr. E. T. Lewis, the former being illustrated by 

 photographs taken by Mr. Wheler, and by the exhibition of one 

 of the ticks referred to, anc the latter by a mounted specimen 

 shown under a microscope in the room. 



Attention was also called to a tick sent up for exhibition 

 by Mr. Wheler, and shown under the microscope by Mr. Lewis, 

 which was remarkable as having scales in place of hairs ; this 

 creature was found on a zebra in East Africa, and had been 

 named by Mr. E. I. Pocock — Rhijyicejyhalus marmorea. 



The President regretted that he knew very little about the 

 creatures which had been described, but hoped some one more 

 familiar with them w^ould make some observations on the subject. 



Mr. Karop said that insects getting into people's ears w^as not 

 so very uncommon, and instanced a case in which an Italian 

 organ grinder had come in distress to the hosjDital to have a 

 number of ordinary bed bugs extracted from his ears. He asked 

 if there were other instances known of this species of tick getting 

 into human ears. 



Mr. E. T. Lewis said that the tick in question had been found 

 in the ears of children in America, and also in the ear of a prairie 

 wolf. It was perhaps worth mentioning that certain species of 

 ticks appeared to have special proclivities for attacking particular 

 parts of an animal, and there were some in Natal which were 

 extremely troublesome from their propensity to get into the ears 

 of horses. He believed that a detailed account of the finding of 

 the two ticks mentioned would shortly appear in the Lancet. 

 The two photographs exhibited were of the dorsal and ventral 

 aspects of the tick extracted from the left ear of the American 

 gentleman referred to, and the tick exhibited in the room came 

 from his right ear. 



The thanks of the Society were unanimously voted to Mr. 

 Wheler for his communications, and to Mr. Lewis for reading and 

 illustrating the papers. 



Mr. D. J. Scourfield read a paper on " The Swimming Peculiar- 

 ities of Daphnia and its Allies, with an account of a new method
