In making a chemical study of the composition of domestic animals of different ages and on different planes of nutrition, it is important to make a study of the composition of their ash and of the ash of similar animals at birth. This paper will deal with the composition of the ash of the new born calf. A review of the work on ash analysis fails to show that any work has been done on the composition of the ash of the new born calf. A number of analyses have been made of the composition of the ash of different parts and organs of various animals and a few analyses have been made of the composition of the ash of entire animals at birth. In order that a comparison of the ash of the different parts of an animal, and of the composition of the ash of different animals may be made, some of the results secured by other chemists are here presented.
