the animal transferred to weak and afterwards to strong spirit. If the 

 skin be softened for about 15 minutes in strong acetic acid, or brushed 

 over with hydrochloric acid, it is easily scraped off, and from young 

 specimens of Scyllium canicula can thus be obtained workable prepara- 

 tions of the superficial veins. If the lateral muscles be cut away and 

 the rest mounted in balsam, the deeper vessels are obtained. 



Of young animals decalcified with 90 per cent, spirit and nitric acid, 

 sections 1/2 mm. thick are easily made. These are stuck on by 

 Fottinger's method and then stained with weak acid carmine. If picric 

 acid be added to the alcohol for washing and dehydration a picro- 

 carmine stain is obtained. The relations of the valves must be 

 examined in uninjected specimens. 



Simple Apparatus for Injecting Fluids for Bacteriological Pur- 

 poses.* — Dr. E. J. Petri's injector consists of three parts, a needle- 

 cannula, a pipette, and a spray-bellows, the tube of which is fitted with a 

 stopcock. The fluid to be injected is sucked up into the pipette, the 

 needle is then fitted on the point, and the tube of the spray-bellows 

 adjusted at the other end. The stopcock is turned off up till now. 

 Then the web-covered ball is distended and the cock turned on. This 

 is found to give sufficient force to inject 5 ccm. of fluid. In case of 

 bellows not being at hand the fluid may be blown in.

Fixing Objects to Cover-glasses.f — Dr. Von Sehlen fixes samples 

 of fluids or any non-viscous matter to cover-glasses by means of 

 albumen. The albumen mixture is made by mixing the white of an 

 egg with an equal quantity of cold saturated boracic acid solution (about 

 4 per cent, of ihe acid). If after being kept a precipitate is thrown 

 down, the solution is cleared by filtration. 



The solution is merely dropped on a cover-glass, and then some of 

 the material to be examined is intimately mixed with it. An even layer
