The seeds of L. sativus are commonly sown in Switzerland for 

 soiling horses, under the name of Gesse. In several parts of the 

 continent a white, light, pleasant bread is made from the flour of 

 the pulse, but it produced such dreadful effects in the seventeenth 

 century, that the use of it was forbidden by an edict of George, 

 duke of Wirtemberg, in 1671, and was enforced by two other 

 edicts under his successor Leopold, in 1705 and 1714. Mixed 

 with wheat-flour in half the quantity makes a very good bread, 

 and appears to be harmless. But bread made with this flour 

 exclusively has brought on a most surprising rigidity of the limbs 

 in those who have used it for a continuance, insomuch that the 

 exterior muscles could not by any means be reduced, or have 

 their natural action restored. These symptoms usually appeared 

 on a sudden without any previous pain. The disease was re- 

 garded as incurable, and being neither very painful nor fatal, those 

 who were seized with it usually submitted to it with patience. 

 " Swine fattened with this meal lost the use of their limbs, but 

 grew very fat lying on the ground. A horse fed some months 

 on the dried herb was said to have his legs perfectly rigid. Kine 

 are reported to grow lean on it, but sheep not to be affected. 

 Pigeons, especially young ones, lose the power of walking by 

 feeding on the seeds. Poultry will not readily touch it, but 

 geese eat it without any apparent damage. In some parts of 

 Switzerland cattle feed on the herb without any apparent harm." 

 Duvernoy Fabbroni, of Florence, says, that the government there 

 had cautioned the peasants against the use of Lathyrus sativus, 

 in 1786, swine having lost the use of their limbs, and become 

 pitiable monsters, by being fed on this pulse exclusively. The 

 peasants, however, eat it boiled or mixed with wheat flour, in 

 the quantity of one-fourth, without any harm.
