idea of what was meant, and recommended it to the attention of other 

 members. 



The President said it had been discovered that April 23rd was printed 

 upon their list as the date of the ordinary meeting for that month, and 

 that being Good Friday it would not of course be possible to hold it then. 

 He therefore announced that in consequence of this coincidence the ordinary 

 meeting would be omitted in April. He also wished to announce that 

 the Committee had been considering a proposition brought before them 

 for making an alteration in the bye-laws, with reference to the time for 

 holding their annual meeting, and in accordance with the resolution which 

 they had passed he gave notice that their next ordinary meeting would be 

 made special in order to take the matter into consideration. It had been 

 thought that July was an inconvenient time at which to hold their anni- 

 versary, occurring, as it did, at a period when so many of their members 

 being absent for their holidays, there was generally but a thin attendance. 

 It had therefore been considered desirable, on this account, to alter the 

 period from summer to winter, with a view of obtaining the attendance of 

 a larger number of members. 



The President described at some length a slide he had brought for exhi- 

 bition in illustration of the life history of a parasite of the mole, specimens 

 of which had been found in the nests of these animals. A description was 

 also given of another slide of Anguillulce which he had found to be the 

 chief cause of an apparent disease seriously affecting the cucumber crop in 

 Cornwall during last summer. 



Mr C. Stewart proposed the best thanks of the Club to the President for 

 his interesting remarks concerning a class of creatures in which it was well 

 known that it took a special interest. He also hoped that as the cause of 

 the destruction of so many excellent cucumbers had been discovered, that 

 some practical attention would be directed towards the best means of 

 stopping its ravages 



The thanks of the meeting were unanimously voted to the President for 

 his communication. 



The Secretary informed the members that amongst the other objects 

 exhibited in the room Mr. Xelson w r as showing a microscope fitted with 

 Mr. Campbell's fine adjustment described at the last meeting.
