sand. The bag was untied over a small bucket of sea 
water, into which 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 din. 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 Algee 
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 Podocerus 
tsopus in March and April.
