By weight.

(Used)

300  300   of my minute drops weighed 13 gr. 96 weighed carefully by Horace

(There is some loss from evaporation) 

.0465

∴ is 1/19.4 of a minim. 

On this occasion I endeavoured to take as large drops as possible

I then took 200  200  drops with care, as much as possible such as I used & weighed in very light vessel with care & this weight was 2.055 gr

Hence each drop weighs .010275 of gr. & each equal 1/89 of a minim.

Thinking that there might be some error in the 300 drops supposed to weigh 1396 gr. I took out of same vessel by pin 150 drops as large as I could — often dipping the pin several times.

These 150 drops weighed 5.83gr 

∴ 300 drops wd weigh. 11.66 gr.

And one drop wd weigh .0388 grs. 

An 1/23.5 of a minim

If I assume each drop is 1/20th of a minim, I certainly shall not err.  be far wrong  in the maximum quantity given t the 3 glands.—
