1 . Hyoscyamine crystals. Crystallised alkaloid from Hyoscyamus niger and 

 alb., pi-oduced for the first time in larger quantities and brought into the 

 market ; crystallised in snow-white needles. According to the investigations 

 of Dr. Harnack at Strassburg, and Dr. Fronmuller in Eiirth (which, however, 

 have not yet been brought to a conclusion), this preparation is exceedingly 

 effective, and is in this respect almost equal to atropine. 



The smallest dose which paralyses the termination of the vagus of the 

 heart of a frog, consists of 1/200 milligramme (0-000005). (Raising of the 

 suspended beating of the heart by Muscarin) the dose which still produces 

 enlargement of the pupil of a rabbit, is 1/250 milligramme (0*000004) 

 [Harnack] .) 



2. Amorphous Hyoscyamine. Amorphous alkaloid from Hyoscyamus niger 

 and alb. The smallest dose which paralyses the terminations of the vagus of 

 the heart of a frog is in this instance 1/100 milligramme (0-000001, Harnack). 



3. Ditaine crystal. Crystallised bodies from the cortex dita of Echites 

 scholaris, only recently introduced into medicine.
