Since that time no analyses of the inorganic composition of meconium have been made or reported in the literature. The analyses of Müller and of Zweifel were carried out in conjunction with their studies of metabolism during starvation on the professional fasters, Cetti and Breithaupt. According to Zweifel the dry matter of meconium amounts to 20 per cent., whereas Davy3 in an earlier analysis reported that the dry matter was 27.3 per cent. of the meconium. The total ash was 5.1 per cent. of the dry matter in Zweifel's experiments, and 6.2 per cent. in Müller's. In horse meconium Müller found the ash to be 9.33 per cent. of the dry matter. The following table is taken from Müller's work. The results are expressed in
