Characteristics.-The Hop-hornbeam, Ostrya virginica, is sometimes regarded as a variety of the common Hornbeam naturalised in America, though native to Southern Europe. The chief difference between them is that Ost. vulg. has pendulous and Ost. virg. upright catkins. The wood, from preparations of which the provings by Burt and others were made, is exceedingly hard and heavy. The symptoms show a marked action on the liver, with the usual dull headache and pain in back and shoulders; cutting, sinking pains in abdomen. Allen put in italics the following: "Tongue coated yellow at root." "Loss of appetite for breakfast and dinner." "Frequent nausea with the dull frontal headache." On the other hand there is increased appetite; hunger wakes the patient at 4 a.m.; and sinking at epigastrium. Sickening pains were much complained of. Some of the stools were very black. The symptoms were < moving; stooping; walking. < 6 a.m.; 4 a.m.; 3 p.m.
