The vitamin B content of grass seeds in relationship to manures

SINCE carrying out this work we have noted that Colonel McCarrison in 1924 published in the British Medical Journal his results on the effect of " artificial" and also cattle manure on the nutritional value of certain grasses. We have also found that G. H. Hunt at Ohio Agricultural Experiment Station in December 1927 performed certain experiments on the effect of what we now call artificial manures on certain wheat plots. We were unaware of this work until a few weeks ago, but we note that our work confirms McCarrison's.
