sand. The bag was untied over a small bucket of sea 

 water, into wiiich the sand was dropped and, after being 

 well stirred round with the sand, allowed to settle for a 

 few seconds, when the water was poured through a muslin 

 bag with a moveable ^in. brass sieve over its mouth to 

 stop the larger pieces of weed, &c. Most of the Crustacea 

 pass into the bag with the water, and after repeating the 

 stirring and straining process the sand is thrown away. 

 The dredge is put out again as soon as it has been 

 emptied and is working while the washing and straining 

 is going on. The muslin bag containing the living 

 animals collected is then everted into a wide-mouthed 

 glass jar (a French plum jar is the best) filled with sea 

 water. This may be taken home and the contents emptied 

 into dishes when most of the Crustacea will swim out of 

 the weed and sand that still remains and be captured by a 

 small muslin ring net ; or the bag may be at once turned 

 out into a bottle of spirit, or spirit, glycerine and water, 

 to be examined at leisure. The number of creatures that 

 are taken by this method in places that are absolutely bar- 

 ren to the dredge with a net bag, is astonishing. I have 

 to thank Dr. Norman for showing me this excellent device^ 

 In shore-hunting it was found a good plan to wash Algge 

 in a bucket, pouring the water after several such washings 

 through a muslin net which is then treated as above. 

 This appears to be the best method of obtaining Fodocerus 

 isopus in March and April.
