    Of these nasal specula there are many kinds, and some prefer one, some another. The two best, perhaps, are those known as Robert and Collin’s speculum (fig. 3), a double-bladed affair, with a broad trumpet-shaped orifice, which is dilated and held : open by means of a screw arrangement upon its side, and the Fig. 4. Frankel’s nasal speculum. wire speculum (fig. 4), somewhat similar to a dilator used by ocu- lists for separating the lids. Both these are good; the first is a favorite one with me, but I not unfrequently use an ordinary ear speculum, especially with small children, and find it answers a good purpose. Thudichum’s speculum is useful for operations in the anterior nares. With these simple means alone then—viz., those thus far alluded to—you will be able to see all of the anterior nares that there is to be seen, without the use of further instru- mental assistance, although many other aids have been devised, which will be found in practice more of a hindrance than a help.
