bercula, which, though they vary in colour as much as the feelers, yet are con- 

 stantly found to be placed on the edge or periphery of the disk, and consequently 

 afford, together with the insertion of the feelers, a certain mark, by which this 

 animal, so variable in its colour and shape, may be at all times known and dis- 

 tinguished from any other sort belonging to this tribe.

Xy. An Account of the Cicuta,* recommended by Dr. Slorke, By William 



Watson, M.D., F.R.S. p. 8p. 



Dr. W. observes that in a paper he had a short time before presented to the 

 R.S. he had endeavoured to demonstrate that the Cicula major which, since the 

 publication of Dr. Storke's work at Vienna, had been used medicinally in England, 

 was the plant intended by that gentleman ; and not the Cicuta aquatica, as had 

 been suggested by some practitioners here. And Dr. Storke had removed every 

 doubt, which could remain, by transmitting hither some leaves of the Cicuta 

 major, or common hemlock, which grew at Vienna, and was of the same species 

 with the plant so denominated here. 



As Dr. Storke informs us, that, since the publication of his treatise, he has re- 

 ceived letters from almost every part of Europe, confirming his good opinion of 

 the virtues of the Cicuta, and as he is about to publish a 2d treatise on the same 

 subject, containing still more extraordinary accounts of cures, brought about by 

 administering that plant ; there is no doubt therefore, but that endeavours will be 

 made here, to confirm the truth of the doctor's assertions ; more especially as some 

 of the diseases in which Dr. Storke found the Cicuta attended with great success, 

 are such as are of all others the most shocking to human nature, and have, by too 

 long experience, been found to give way to no other means. Hence it is highly 

 important to every one, more particularly to physicians, that the very plant di- 

 rected by Dr. Storke be admmistered, and no other instead of it, either through 

 inattention or want of knowledge ; as judgment in the physician is of no real 

 service, unless his prescriptions are faithfully prepared. 



For these reasons, it may not be improper to inform those medical practitioners, 

 who are not conversant in botany, and who may yet be desirous of trying the 

 effects of the Cicuta, that at this time of tlje year there is another plant, growing
