A study is presented of 100 normal electrocardiograms of school-boys, ranging in age from 5 to 15.
The various deflections and “intervals” of the normal electrocardiogram are measured and analysed; corresponding figures and values from American and European authors are presented for the sake of comparison.
Normal electrocardiographic standards are presented for the use of practitioners in India. The results of the investigation are briefly presented in a tabular form (see Tables XXVIII and XXIX).

An investigation of the chemical composition, and the nitrogen partition in the nitrogen complex of the garlic (Allium sativum) has been carried out.
Exhaustive extraction with water removes 80% of the total nitrogen of which 67% is in the non-protein form, largely made up of compounds precipitable by phosphotungstic acid in 5% sulphuric acid.
The non-protein nitrogen extract has been fractioned for nitrogen distribution. Arginine, cystine, tyrosine and tryptophane have been determined independently. These results point out the existence of some type of compounds decomposing under the influence of alkali with the liberation of ammonia.
Garlic contains appreciable amounts of most of the important amino acids, its richness in lysine and histidine suggests that it may be of value in nutrition.

Garlic contains 30·5% of the total phosphorus as phytin, which forms the major fraction of the barium-precipitable acid-soluble phosphorus.
The barium-soluble fraction of the acid-soluble phosphorus is largely composed of the resistant hexose mono-phosphate 65%, and labile phosphorus compounds 35% whose nature is not known.
