Until 1930, no organised biochemical work had been undertaken in New Zealand on the blood and urine of normal cattle and sheep. Josland decided that his first priority should be an attempt to determine the normal values and limits for the purpose of standards. This was done and became the standards upon which future biochemical investigations were based. Josland directed biochemical work towards various cattle and sheep diseases, including eclampsia, temporary sterility in cattle and pulpy kidney in lambs, blood from the latter showing no deviation from the normal.
