Fennessy, E. B. — Microscopic. 



[A very pretty slide, and one very easily made, is the raphides in the sap 

 of tlie daffodil. It is only necessary to squeeze out a drop of sap from 

 the flowering stem on to a slide, and on its drying, which may occur 

 spontaneously, or be done over a spirit-lamp, we find hundreds of crystals 

 strewn over the field of view. With the polariscope they are exceedingly 

 interesting and brilliant. If we drop over the warmed glass a little 

 Canada balsam, we can press on a cover-glass.]

 Kain, C. H. — Some thoughts about Mounting. 



[Discussion of various media. — " Some experiments by Mr. E. E. Read, of 

 the Camden Microscopical Society, would seem to indicate that cosmoline 

 may prove a valuable medium in which to mount the starches. The 

 starch-grains are certainly remarkably well displayed in it. How perma- 

 nent the mounts may prove is a question of time. It is not improbable 

 that several of the petroleum products — even the plebeian kerosene itself — 

 may be found not unworthy of the microscopist's attention." — "Dr. 

 W. W. Munson some time ago called attention to the preservative 

 properties of a solution of hydrate of chloral, and the medium is
