Use milt that has been bottled up and sent by mail 100 miles, 500 miles, 1,000 miles. 8. Use milt that has been forced f by putting male in warm water, and note the degree of impregnation. 9. Use milt that has been frozen. 10-12. Repeat experiments 6, 7, 9, using eggs instead of milt. 13. Put ripe eggs with milt that has been exposed to the air 5 minutes, 20 minutes, 30 minutes. 14. Put good milt with eggs that have been exposed to the air 5 minutes, 20 minutes, 30 minutes. 15. Use ripe eggs with milt that has been diluted with water 2 minutes, 5 minutes, 20 minutes. 16. Use good milt with eggs that have been kept in water 2 minutes, 5 minutes, 20 minutes, 30 minutes. 17. Compare the percentage of impregnation of eggs taken in Ainsworth's races and CoUins's roller box with those taken by manual pressure. Experiments in general with Ei^gs. 18. Pack eggs in wet moss {Sphagnum) as soon as taken, and examine when nearly ready to hatch, and note the mortality. * See p. 104. t See p. 115, Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Stone, Livingston, 1836-1912.
