mend a K solution of potassium permanganate and 

 aluminium sulphate as a chemical antidote, one quart be- 

 ing enough for three to five cows, or seven to ten horses ; 

 and injections of one-half to one grain of atropin. Marsh 

 and Clawson report poor results from this treatment and 

 recommend the use of Epsom salts and injections of a 

 combination of physostigmin salicylate, pilocarpin hydro- 

 chloride and strychnin sulphate, supplemented by hypo- 

 dermics of dilute alcohol where weakness is very pro- 

 nounced. All excitement should be avoided and the ani- 

 mal kept with its head higher than the rest of the body. 

 Where bloating occurs, it should be relieved by paunch- 

 ing. 



As noted above, many species of Larkspur are found in 

 Canada and the United States, but a detailed classification 



is unnecessary- All have leaves with deep

palmate lobes and flowers in a loose elongated 

 terminal cluster. The flowers vary from bright blue to 

 pale violet and yellow, both sepals and petals being col- 

 oured. Each is provided with a long spur. The glisten- 

 ing black seeds are contained in erect, horned capsules. 

 The species are divided into two groups. The low Lark- 

 spurs grow from six inches to three feet tall and the 

 foliage dies and dries up at seeding time. The tall spe- 

 cies are three to six feet high, and retain their leaves for 

 a longer period.
