NEWS AND NOTES. 



Temporary Labelling of Glass Slides. — It is often necessaty in the micro- 

 scopical examination of material, to attach a label to temporary preparations. 

 Ordinary gummed paper has doubtless served for this purpose in most labora- 

 tories, as it has in ours, but selecting and attaching a proper piece often requires 

 more time than a hurried worker likes to give. 



Mr. W. A. Orton, formerly of the University of Vermont and now an assist- 

 ant in our division, has in use a method which saves much time and much 

 gummed paper, and is especially handy in the field. He has kindly permitted 

 me to call it to the attention of those readers of the Journal who may not already 

 have in use a satisfactory method of temporary labelling. It is simply the grind- 

 ing for half an inch or more of one or both ends of the slips. The grinding is 

 quickly and easily done with a sand-blast. The ground surface will take pencil 

 notes with the greatest clearness, and can be easily cleaned when desired. The 

 same method of marking may be used for test-tubes. The slides which Mr. 

 Orton has in use were ground for him by Professor Charles Jones of the Chem- 

 ical Department of the University of Vermont, who perfected the sand-blast 

 method of marking laboratory glassware.

Attendance at Marine Biological Laboratory, Woods Holl, Mass., 

 1899. — The Marine Biological Laboratory at Woods Holl, Mass., has just closed 

 its twelfth annual session. The year has been a very successful one, additional 

 courses were offered, attendance considerably increased, and a deep interest 

 manifested. It is the purpose of the management to further broaden the 

 scope of work. A thorough course in nature study will be introduced next 

 year. To care for the increased numbers who are attending, it has become 

 necessary to provide more room. An addition to the botany building and one 

 new building for investigation laboratories are expected next year. We give 

 herewith names of those in attendance this year :
