HEMLOCK—HOG^S LARD. 107 



There is an extract made from hemlock, 

 which, when prepared, is a very convenient 

 form, and not less efficacious than the pow- 

 der. 



The dose is about a dram, but this also 

 may be gradually augmented to a conside- 

 rable quantity. 



A decoction of green hemlock, is said to 

 be an useful fomentation in painful wounds 

 and tumours. 



HENBANE. This plant also is a power- 

 ful narcotic, and free from the constipating 

 effect of opium. It has not hitherto been 

 used in veterinary medicine, though likel}' 

 to be found beneficial. I have tried a solu- 

 tion of the extract in water, in chronic in- 

 flammation of the eye, wliere the interior 

 parts were very irritable, and I think with 

 good effect. It certainly deserves a far- 

 ther trial in this way. 



The seeds are said to be the most power- 

 ful part of the plant ; but the powdered 

 leaves and the extract are more commonly 

 employed.
