NOTES. 
Note 1.— Owing to a lack of literature on the subject, I have provisionally named 
this worm Anguillula arenaria, but it may belong to a different genus. If an Anguil- 
lula, it is very near the A. brevispinosus, but as the spine disappears in mature forms, 
I have called this A. arenaria. 
Note 2. — This information came from one of the oldest citizens, who learned of it 
from the Spanish residents in 1820. 
Note 3. — Letters received from correspondents at nearly every important town gave 
the data. 
Note 4. — Messrs. Berckmans, Onderdonk, Munson, and Stelle are referred to. 
Note 5. — I kept fully developed pregnant females in a watch glass dry for six months, 
and when wet, they expanded, and the grown worms within the cysts in the uterus 
resumed motion. 
Note 6. — The average weight of a cubic foot of ordinary sandy surface soil is 6,002,625 
grains, equal to 86.08 pounds avoirdupois ; this at the temperature of 70°, the soil 
being air-dry. 
Note 7. — The quantity required to saturate a cubic foot was 2.3 gallons of the kero- 
sene emulsion. 
Note 8. — The amount of lime used was 20 pounds to the tree, forty-nine trees to the 
acre. 
Note 9. — Water poured upon the pots percolated through the soil and out at the 
hole in the bottom of the pot. This was allowed to evaporate considerably and exam- 
ined with magnifier 350 diameters, eye-piece B, objective one-half inch. 
Note 10. — Radishes and turnips are very susceptible to the Anguillula. (See Plate 
III, d rawn from actual specimen, natural size.) 
Note 11. — A common practice among the “ old-time ” slaves, who tell me it was the 
rule made by the old whites as far back as 1805. The reason they gave was ‘‘the 
peach loves clay and yellow sand.” 
Note 12. — I could only approximate the growth and development by the use of such 
plants as the Cow-pea and Radish — planting seed in infected soil, and at certain dates 
pulling up the plants and examining the knots, making a careful sketch, drawn to 
scale, each time. All attempts at cultivating in fluids failed. 
Note 13. — By softening the exterior with a solution of caustic potash, snipping off 
the head and gently pressing the body in fluid, with a cover glass, the uterus exuded 
as shown in Plate XIX.
