94observed by Prof. Rogers), which is_indicated by my analysis,is a very interesting fact. It is to be regretted that a specimenof the water from which this calcareous deposit was formed,was not also collected, in order that its composition might becompared with that of the deposit itself. Farther remarksupon the presence of the chloride of calcium are reserved untilthis can be done, and also a determination made of the amountof this salt contained iu the mineral.As remarked by Prof. Rogers, this calcareous sinter shouldgive, when burnt, a very white and goodlime.V.Calcareous sinter from the farm of Benjamin P. Van Sickles,Petersville, Sandisten Township, Sussex County.Stalactitic in its structure, and contains small pebbles ofquartz and sandstone. When heated upon platinum, i_ presentsthe same curious phcnomenon of repulsion as I.A. Thepresence of organic matter was indicated by a brown color ofthe residue left after solution of the ignited substance in chlorohydricacid, which brown color disappeared before the blowpipe.The solution formcd by boiling water with the pulverizedsubstance has a smell like moist chalk, no color or alkalinereaction, m_d contains much chloride of calcium and otherchlorides.
