9. Mr. Smith's blood. Spores, enlarged white corpuscles. Two sporangia? Gemiasma dark brown, black. Mr. Smith is superintendent Congressional Cemetery. Lived here for seven years. Been a great sufferer with ague. Says the doctors told him that they could do no more for him than he could for himself. So he used Ayer's ague cure with good effect for six months. Then he found the best effect from the use of the Holman liver ague pad in his own case and that of his children. From his account one would infer that, notwithstanding the excellence of the ague pad, when he is attacked, he uses blue mass, followed with purgatives, then 20 grains of quinine. Also has used arsenic, but it did not agree with him. Also used Capsicum with good results. Had enlarged spleen; not so now.
