Note 200 — RECREATIVE.
Reading edition
Pure muriate of soda does not contain any water in its crystallized state except what lodges in the interstices of the crystals, therefore the weight of that, as it exists in the water, would not exceed the weight above given; 30 grains muriate of lime indicate 51 grains crystallized muriate, 8.81 grains muriate magnesia indicate 15½ grains.
