68 CUKRENT NOTES AND MEMORANDA. 



slide, and put on a thin cover-glass, which must be supported so as 

 not to touch the object ; leave it until thoroughly soaked. If 

 necessary, remove to a clean slip for finally mounting. Drain off 

 the oil of cloves and put on a quantity of Canada balsam in 

 benzole; arrange the creature on the slide. Let the balsam harden 

 a little, and then the object will not float off, as often happens 

 when a quantity of balsam is used at once. Lower the cover on 

 to the object. It is better not to put enough balsam to fill the 

 space under the cover, as the balsam supports the cover if it does 

 not reach the edge, but if it reaches the edge it is apt to draw 

 down the cover and crush delicate objects. A few pieces of thin 

 glass to support the cover are a great protection to the object, or 

 better still, a few tiny glass beads. 



Finish off with a ring of Bell's cement, but this must only be 

 done if the cover is supported as recommended. 



We regret that our article in the present issue on the 

 FoRAMiNiFERA OF Galway provcd to be too long for insertion 

 in one part. We hope to complete it in April, and at the end of 

 the article shall give the explanation to the four plates, with the 

 exact magnification of each form. 



Whilst correcting the last proof-sheet of our Journal, we 

 received a communication from S. C. Hall, Esq., President of the 

 Carlisle Microscopical Society, from which we learn that 

 Dr. W. B. Carpenter has been made Hon. Vice-President of that 

 Society. 



In a letter in which Dr. Carpenter accepts the office of Vice- 

 President he suggests that Microscopists should study more thor- 

 oughly the life history of Diatoms, Monads, and Disease-germs. 



We regret that space forbids our publishing the Doctor's letter 

 in exte?iso, but hope to refer to it on another occasion.
