ROBERTS, Thomas Alexander.—“ Preserving potatoes and “ certain other vegitables,” by taking “potatoes that are thoroughly “ ripe, and before they have grown in the spring,” and “ cutting “ out ” or otherwise destroying “ the eyes or germs;” “ the more “ they are kept from the air the firmer they will be.” “ Carrots, “ turnips, and other vegitables may be preserved by cutting away “ or destroying the growing or germinating parts.” [Printed, 3cl. See London Journal {Newton’s), vol. 10, p. 257; and Register of Arts and Sciences, vol. 4, p. 31.] A.D. 1827, July 12.—N° 5523.
