DISEASES OF THE NERVOUS SYSTEM 95 



motor paralyses, pareses and paralyses of the posterior quarters, 

 paralysis of the recurrent nerve (roaring), paralysis of the bladder, 

 penis, tail and rectum, amblyopia and amaurosis, lead paralysis, 

 and chloroform, chloral hydrate and other narcotic poisonings. 

 The dose of strychninae sulphas internally and subcutaneously 

 (not intratracheally) is one-tenth of a milligram for each kilogram 

 of body weight; therefore, the dose for horses is 0.05-0.1, grs. 

 ^ to iss; cattle, 0.05-0.15, grs. M to ij ; sheep and goats, 0.005, gr. 

 3/40; swine, 0.002-0.005, gr. 1/40 to 3/40; dogs, 0.001-0.003, gr. 

 1/70 to 1/25; cats, 0.0005-0.001, gr. 1/140 to 1/70; fowl, 0.0002- 

 0.0005, gr. 1/340 to 1/140. 



2. Veratrina. Veratrin. The chief remedy in fatigue and 

 paralyses of the striated and smooth musculature of the body; also 

 a very powerful excitant to the entire nervous system. It is used 

 principally in cattle practice, in which it is employed especially in 

 the treatment of antepartum paralysis, exhaustion after parturi- 

 tion, parturient paresis and atony of the musculature of the rumen. 

 In addition, it is frequently prescribed in heart weakness and in 

 conditions of collapse, especially in the course of narcotic poison- 

 ings. The subcutaneous dose of veratrin in alcoholic solution 

 for horses and cattle is 0.05-0.2, grs. ^ to iij ; sheep and goats, 

 0.01-0.02, gr. 1/8 to }4; dogs, 0.001-0.005, gr. 1/70 to 3/40; cats, 

 0.001, gr. 1/70. The crude drug, veratrum, and tinctura veratri 

 (dose per os for horses and cattle 5-10, 3i to ijss) are less frequently 

 used than the alkaloid because of their slower action. 



3. Atropine and hyoscine (scopolamine). These are among the 

 strongest nerve stimulants and are specific in heart weakness, 

 threatened respiratory paralysis, and in poisoning by chloroform, 

 morphine, eserine, arecoline and pilocarpine. Dose of atropinae 

 sulphas for horses and cattle, 0.05-0.1, gr. % to iss; sheep and 

 goats, 0.01-0.05, gr. 1/8 to %; swine, 0.01-0.03, gr. 1/8 to 1/3; 

 dogs, 0.005-0.05, gr. 3/40 to %; cats, 0.002-0.005, gr. 1/40 to 3/40. 

 The dose of hyoscinae hydrobromidum subcutaneously is one- 

 tenth these quantities: horses and cattle, 0.01-0.05, gr. 1/8 to %; 

 dogs, 0.005, gr. 3/40.
