The concept of the mineral classification in the Mineral Powder Diffraction File (MPDF) is somewhat different from that used in classical mineralogical references. The goal of the classification is to exploit the crystal chemistry characteristics to the fullest to assist in the identification of mineral phases. The primary criterion is the similarity of the diffraction pattern, which results fr...

gastric juice or mineral acids }11to a proteid and another substance which gives :io proteid reaction. This contains all the iodine (about 14 %) and is known as iodo-thyrin. Very little is known about its chemistry beyond that it is not a proteid, and that it contains all the iodine in organic combination. The iodine found in iodo-thyrin must certainly be derived from the food, but the mere tra...
