To quickly assess the difficulty of the text, read a short excerpt:
That this is a matter of great importance is well shown by a table quoted by Winter Blyth in his work on poisons. From this it would appear that the English and continental species of Hyoscyamus contain * J. O. S. , 189!>, I. XXV, 71 ; 1901, I, XXIX, 72. the largest proportion of alkaloid at or just before the time of flowering. When the fruit is ripened and the plant commences to dry, the whole plant shows a much smaller proportion of active substance. This seems also to be the case with the E...gyptian plant. Dunstan gives the alkaloidal content of the leaves as reaching 1-4 per cent, but I have found as much as two per cent in the dry matter of the green leaves collected at the time of flowering. There are, however, difficulties in dealing with the fresh plant at this stage of its growth owing to the large water content. The plant, when growing in well watered soil, may at the time of flowering contain as much as ninety- five per cent of water. This makes the process of drying difficult and tedious.
