Note 21 — CHAPTER 8.
Reading edition
“It is worthy of remark that in the month of May a very great number of large larvæ exist under the mucous membrane at the root of the tongue and posterior part of the nares and pharynx. The Indians consider them to belong to the same species with the oestrus that deposits its ova under the skin: to us the larvæ of the former appeared more flattened than those of the latter. Specimens of both kinds preserved in spirits were destroyed by the frequent falls they received on the portages.”—Dr. Richardson’s Journal.
