160 SUMMARY OF CURRENT RESEARCHES RELATING TO 



Mr. Griffith's words, and they will promjitly make reparation. Those who kept 

 the turntabhs can scarcely be judged so leniently. Still it is possible that 

 they too misunderstood the offer. At any rate, prompt reparation should be 

 made. If it is not done, the matter should be looked into by the Society, 

 and an example made of the persons who so abuse the privileges of membership. 

 The ' nipping ' of fine slides has become entirely too frequent to be pleasant 

 to those who have to stand the loss. The writer's cabinet has suftVred a greater 

 or less depletion from this source at every meeting that he has attended, and 

 the 'nippers ' must henceforth be on their good behaviour or exposure will most 

 certainly follow."]

[" From A. Y. Moore we have received another novelty, namely, preparations of the 

 diatom Arachnoidiscus, plated with gold by electricity. These make very rich 

 and elegant objects, and present some interesting features, among which may be 

 noted the prominence with which the rays or ribs stand out. Dr. Moore states 

 that ' by making the diatom opaque, points of structure may be determined 

 which probably would not otherwise be seen.' Certainly, independent of any 

 scientific value they may have, these elides constitute a very attractive novelty."]
