Penna., which had been poisoned by eating the leaves of this plant grow- 

 ing in a piece of woodland into which the heifers had been turned to browse 

 and which was usually closed to the feeding of cattle. All of the heifers 

 in the herd were poisoned, but when the writer visited it, all of the ani- 

 mals, but two, had partly recovered through the care of the veterinarian 

 in charge, Dr. D. S. Deubler. The two heifers., which were still suffering 

 from the poison walked about with unsteady gait, they hung their heads 

 low and showed a general lack of activity with considerable frothing at

 vania, was called on the evening of December 24, 1894 to see the goats. 

 Six of them died in the Veterinary Hospital from the effects of the laurel 

 poison. Horses have died from eating the leaves, and in May 1895, a 

 monkey was killed at the National Zoological Park at Washington, D. C. 

 by eating a few flowers and leaves offered to it by a visitor. The honey 

 made from the flowers of the mountain-laurel by bees is said to be poison- 

 ous. Cases of poisoning may be expected, therefore, from time to time 

 in the region where this shrub grows which is from Canada to Maine and 

 the Allegheny mountains through West Florida, Ohio, Kentucky and
