To J. D. Hooker   6 November [1873]

[Down]

I would suggest to remove by pipe about 12 fluid from a pitcher, & then add 2 or 3 drops of infusion of raw meat. After 24o test for acid.— remove by sucking pipe all fluid,— sacrifice the pitcher & compare the glands of very same pitcher (for aggregation) which had & had not received any of the infusion.—1
