The proportional value which the grass at the 

 time of flowering bears to that at the time the seed is 

 ripe, is as 4 to 13. 



* The weight is avqirdupoisa ; Ibs. pounds, oz. ounces, dr. drachms. Th 

 weights not named are, quarters of drachms, and fractions of quarters of drachms - T 

 thus 7. 1 1-4 means 7 drachms 1 quarter of a drachm and 1-4 of a quarter.
