Translation of "stalactite" into Japanese

These stalagmites may eventually connect to the ceiling, perhaps joining a stalactite to form a column.

それらの石筍は,ついに天井に届き,鍾乳石とつながって円柱のようになったりすることがあります。“

Sometimes the water does not completely evaporate but falls, depositing the beginnings of an inverted stalactite, or stalagmite.

時々水は,完全に蒸発せずに落下して,逆の形の鐘乳石,つまり石荀をつくりだす。
