“…Briefly stated, the method consists in mixing known weights of lycopodium and of the material to be ~p r i l i g 2 1 examined and suspending the mixture in any convenient volume (not necessarily a known volume) of a suitable suspending agent such as mucilage of tragacanth, olive oil, castor oil or a mixture of these oils. (For a discussion of suspending agents see reference 16.) The suspension is thoroughly shaken up in a stoppered weighing bottle or in a corked tube and a small drop is transferred to a slide by means of a glass rod and covered with a cover-glass.…”

“…One can hardly expect the critical observer to accept counts of masses of fibers of uncertain length and in bundles of varying numbers, as has been suggested by some workers. 16 Before an acceptable process c m be devised, it will be necessary to discover some method of eliminating the uncertainties resulting from these disturbing factors.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
