Unfortunately the sample of blood could not be analyzed since the tube was broken in transit, and the blood had escaped* I did not report this to you iionediataly, nor did X send you another tube and a needle since I realized that Mr.H^flftmlght not be under your care for any prolongeJ^er^Jd of time, and a further sample might be difficult to obtain. There would be a certain advantage in obtaining another sample of blood, but X shall await word from you before sending the necessary container.
