SEPARATING FORAMINIFERA FROM SAND.—If you throw dried 
sponge sand into water, slowly, all the foraminifers will sink, and 
sand will float on the water. F slide dipped under the floating film 
of grains will bring up only sand. You can safely skim off and 
throw away all that does not sink with a little stirring. Then.the 
sunken part should be dipped out, about a dessert-spoonfal at a 
time, into a small saucer, and water enough to just fairly cover 
them put in, and all floating grains stirred down. Then by a cir- 
cling movement of the hand the foraminifers will be got to the top, 
and ‘by gradually tipping the saucer and slowing up the movement 
they can be worked to one edge of the little pile of sand, and 
thence carefully dipped up with a rubber bulb pipette. In this 
way they are got almost pure. Only a little sand must be washed 
at a time, or not all the foraminifers will be got out, and very little 
water must be used or sand will get mixed with them. Much 
water moves the light sand, but a shallow wave seems not to stir 
it, but yet rolls the shells along—C. M. Vore 
NATURALISTS DiRECTORY.— The TADRE e for 1879, 
recently published by S. E. Cassino, at Salem, Mass., contains by 
far the best register of American ae one yet published. It 
will be found especially useful to the microscopists who desire to 
arrange for exchanges in different parts of the country.
