We cannot tell precisely what quantity of potassium chlorate will be 

 administered in the 3vi. ordered in this prescription, but we can be as- 

 sured that it will not be larger than 3 drams, which is a small dose for 

 the horse. 



'Suppositories are occasionally prescribed to dogs. The excipient is 

 cacao butter, of which about 15 grains is required. We will write a pre- 

 scription containing iodoform and extract of belladonna root, to be dis- 

 pensed in suppositories for a medium-sized dog. The Latin for iodoform 

 is iodoformum, genitive iodoform-i, of iodoform; dose, gr.^/o- The Latin 

 for extract of belladonna root is belladonna, genitive belladonn-CE, of bel- 

 ladonna; extractum, genitive extract-i, of extract; radix, genitive radio-is, 

 of root; dose, gr.^. The Latin for cacao butter is oleum theobroma; 

 oleum, genitive ole-i, of oil; theobroma, genitive theobromatis, of theo- 

 broma. The quantity of cacao butter may be safely left to the discretion 

 of the pharmacist. We will multiply the dose by ten, to make ten sup- 

 positories.

Sig. Introduce one into the bowel every 4 hours. 



JoHx Smith, D. V. M. 



In writing prescriptions for ointments the degree of dilution of the 

 medicinal substance, or substances, must be determined. In case the dilu- 

 tion is done in percentage, the metric system is particularly useful. A 

 5-per-cent. ointment of the yellow oxide of mercury is of value in some 

 cases of conjunctivitis. We will write for 5 Gm. 



The Latin for yellow oxide of mercury is hydrargyrum oxidum 

 flavum; hydrargyrum, genitive hydrargyr-i, of mercury ; oxidum, genitive 

 oxid-i, of oxide ; flavum, genitive flavi, of yellow. 



The excipient will be simple ointment. Latin for simple ointment is 

 unguentum, genitive unguent-i, of ointment. If we order 5 Gm. of simple 

 ointment we can determine the amount of mercury necessary to form a 

 5-per-cent. preparation with it by simply moving the decimal line forward 

 two places, .06, which will give a 1-per-cent. ointment of mercury; and 

 then, by multiplying by 5, .05X5^=-25, we secure a 5-per-cent. ointment.
