Nineteen free amino acids and four ninhydrin-positive compounds were detected in the haemolymph of fifth-instar nymphs of Rhodnius prolixus by the technique of thin-layer chromatography. On the sixth day after feeding, tyrosine and tryptophan appeared in the haemolymph. Their concentration increased until the 12th day when testing stopped. The concentrations of alanine, asparagine, cystine, isoleucine, phenylalanine, and threonine fluctuated moderately from day to day. The results obtained by thin-layer chromatography differed from those of a similar study in which the technique of paper chromatography was used.

In field investigations on the relative resistance of varieties of peas, Pisum sativum L., to the pea aphid, Acyrthosiphon pisum (Harr.), the average number of aphids per terminal growth for 13 years (Maltais, 1937, 1950, 1951, and unpublished technical report, 1950-54) for six varieties was as follows: Perfection, 39.6; Daisy, 32.6; Lincoln, 35.6; Laurier (H-103), 9.8; Champion of England, 11.8; and Melting Sugar, 16.8. In a preliminary investigation by Auclair and Maltais (1950), 11 free amino acids were detected in pea plant extracts by paper chromatography. From a visual comparison of chromatograms, the variety Perfection appeared to contain a higher concentration of most free amino acids than the variety Laurier. This is a report on the quantitative estimation of the free and total amino acid contents of the three susceptible varieties (Perfection, Daisy, and Lincoln) and the three resistant varieties (Laurier, Champion of England, and Melting Sugar) by the method of paper chromatography.

The composition of free amino acids and proline content in various parts of <i>Dactylis glomerata</i> panicles at different stages of their development were determined by paper chromatography and electrophoresis. The proline level in the spikelets was found to change widely in the course of their development. The results are discussed with reference to the role of proline in the nitrogen metabolism of plants.

Tomato plants which had been cultured in the absence of molybdenum were provided with molybdate, and the consequent changes in the relative amounts of the free amino acids and amides were followed over an experimental period of 4 days. The technique of quantitative paper chromatography was used to estimate the individual free amino acids and amides, and the results are .expressed on a dry weight basis.

Abstract A method has been described for the chromatographic separation on paper of free amino acids in human blood serum in which the previous desalting is not necessary.
