| Alcohol | 30 | ounces. |
| Ether | 40 | ounces. |
| Schering’s Celloidin* | 1 1⁄2 | cakes. |
* Hance’s D. C. gun-cotton may be used instead of the celloidin.
Cut the celloidin into thin strips, or, if it be hard, break it up in a clean mortar, and dissolve in the above mixture of alcohol and ether. When dissolved, this forms the collodion.
