[907] In a cod-fish, weighing 20 lb., Mr. F. Buckland ('Land and Water,' 1867, p. 57) calculated the above number of eggs. In another instance, Harmer ('Phil. Transact.,' 1767, p. 280) found 3,681,760 eggs. For the Ascaris, see Carpenter's 'Comp. Phys.,' 1854, p. 590. Mr. J. Scott, of the Royal Botanic Garden of Edinburgh, calculated, in the same manner as I have done for some British orchids ('Fertilisation of Orchids,' p. 344), the number of seeds in a capsule of an Acropera, and found the number to be 371,250. Now this plant produces several flowers on a raceme and many racemes during a season. In an allied genus, Gongora, Mr. Scott has seen twenty capsules produced on a single raceme: ten such racemes on the Acropera would yield above seventy-four millions of seed. I may add that Fritz Müller informs me that he found in a capsule of a Maxillaria, in South Brazil, that the seed weighed 42½ grains: he then arranged half a grain of seed in a narrow line, and by counting a measured length found the number in the half-grain to be 20,667, so that in the capsule there must have been 1,756,440 seeds! The same plant sometimes produces half-a-dozen capsules.
