The work on that portion of this paper which deals with the detection of blood dried on various fabrics and leathers, and the effects of age, soil, and certain chemical reagents (qualitatively) was carried out by Mr Sanger, partly in conjunction with myself, as the subject of his Thesis for the Degree of M.D. Subsequently I repeated our previous work and added all the quantitative determinations. We are indebted to Dr Nuttall for suggesting the main lines of this investigation and for the aid he has given us in our work.
