A liquid which I have tried but few times,but which has given satisfaction, is made by mixingone part of glycerine with two parts of a 2% solutionof corrosive sublimate, and adding to this mixturecrystals of chloral hydrate in the proportion of 2 chloral to each 100 cc. of the liquid. This liquidkeeps the animal pliant, does not destroy the color,and seems to bring out the nerves more distinctly. Necessary Dissecting histritments.—Each studentshould be provided with a small case of dissecting in-struments containing at least the following things: :=3>. p Fig. I.—Instruments. 12 INTRODUC TION. Two dissecting scalpels, one large and one small. Two dissecting forceps, one large with blunt ends,and one small with fine points for more delicate work. Two pairs of scissors, one with large blades forcoarse work and one small pair for fine dissection. One seeker, an instrument of the form shown in II,Figo ic This will be found very useful in dissectingnerves, blood-vessels, etc., when by careful tearing w^iththe seeker instead of cutting with the scalpel or scis-sors structures may be revealed which otherwise wouldbe destroyed. Several weighted hooks of the kind shown in IV,Fig» lo These consist simply of a strong hook towhich is attached a cord about two feet in length, car-rying at its other end a lead weight. The most con-venient weight to use is about 125 grammes, thoughit is well to have some lighter and some heavier thanthis. These weighted hooks are useful for holding
