sweet and pleasant, is mistaken for it, and the root, exceedingly 

 poisonous, is eaten to the destruction of life. Children should 

 never be permitted to expose themselves to this fatal mistake ; 

 and yet scarcely a year passes, in which children are not de- 

 stroyed by it. In Bigelow's u Medical Botany," is a full ac- 

 count of its character and operation on the human system, and 

 of its fatal effects. Flowers in July and August. 



2. C. bulbifera. L. Water Hemlock. Stem 2-3 feet 

 high, branching, sleek, more slender than the other ; grows in 

 ditches and about ponds or marshy places, bearing scaly bulbs in

Crantzia. Nutt. 5. 2. 



C. lineata. Nutt. Taken from the following genus ; found 

 near Boston. Nuttall and B. D. Greene, Esq. 



Hydrocotyle. L. 5. 2. Marsh Pennywort. 



The three species found in this State, Americana, umbellata, 

 vulgaris, are of too little importance to require description ; the 

 plants are small, unattractive, and grow in moist or wet woods 

 and hedges. 



From the Greek for icater-vessel, as the depression in the leaf 

 holds a drop of water. 



Daucus. L. 5. 2. 



D. carota. L. The common Carrot. Paslinaca sativa. 

 L. 5. 2. Parsnip. These are two well-known plants of 

 the garden, and seem, in some cases, to be naturalized. The 

 roots are nutritious and healthful, though the parsnip is said to be 

 rather poisonous as it grows in a wild state ; natives of Europe. 



The use of the carrot as a food for cows, and proper nutriment 

 for obtaining rich milk, is fully ascertained by agriculturists ; a 

 native of England and other parts of Europe.
