In this state, the car-bonate of lime simply appears as an amorphous pow-der, and its presence may easily be recognised by theaddition of any dilute acid, which dissolves it witheffervescence. Care must, however, be taken to washthe deposit with water before adding the acid, forunless all traces of adherent carbonate of ammonia areremoved, an effervescence will be excited by the acid,whether the calcareous salt be present or not. Very rarely, the carbonate is found crystallised indense stellse, affecting the circular form, and appa-rently composed of excessively slender prisms (rhom-boids ?) cohering at the centre (Fig. 49). The few in-stances of this kind I have met with occurred in. Fig. 49.
