The point of the tube is wiped, and a 3 per cent, solution of common salt sucked in until the fluid has risen to the point marked loi. The contents of the tube are then thoroughly mixed, and the column of fluid in the capillary tube is removed by blowing into the tube, as the blood would not mix with the solution of common salt. To neglect this precaution, therefore, would vitiate the experiment. Ihe capillary tube must bo carefully cleaned after use, by washing it with distilled water, then with alcohol, and finally with aether, and a brisk current of air blown through it. For the latter purpose Bohni’s air-pump is very suitable. < 0 “ 0 0 «• {”0 P 00 ® 0 e «* 0 0 r p % . 0 »'' e ©o 9 ° 0 ® 0 0 ® c 0 0 e 0 a D e e 0 ^ 0 Oo® ^ 0 a 0 e u ® 0 0 0 0 0 0 0 0 ®o 0 c 0 « P 0 0 0 0 e 0 0 0 D 0 e Of, 0 • ® 0 0 0 0 o 0 •0 P 0 0 0 wo* » 0 0 0' « 0 0 « 0 e e 00 ® o« « 0 ® e r> « • *. 00* • 0 9 0 « * 0 0 0 0 e 0 0 ■ 0 • «.o 9 ® • n 0 0 e^o Fio. 5.-Thoni.vZoi.ss Appar.itus for Counting Blood-Corpuscles.
