This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1904 edition. Excerpt: ...skill is easily acquired and the process gives satisfaction. If the mass begins to break, its plasticity may be restored by working thoroughly in the hands. On the other hand, if handled too much the mass begins to melt. In warm weather or in a warm room it may be necessary to cool the hands from time to time by immersing them for a moment in ice water and wiping quickly. The pill-tile should be kept well dusted with lycopodium or starch while working the mass upon it. Starch is to be preferred in most cases. When a compressing machine is used, the mass is made in the same manner, then placed in the cylinder and forced into the molds. Suppositories made in this way look much like those made by the hot process. The machine and molds should be thoroughly cleaned after each mass, or succeeding lots may appear streaked. COATING SUPPOSITORIES. Suppositories containing hygroscopic substances, as glycerin, or very volatile bodies, are sometimes protected by coating or wrapping them. Flexible collodion, paraffin, and wax are used as coatings. The suppositories are impaled upon needles and dipped quickly into the collodion or melted wax, then set aside until the coating has hardened. These are good protective agents, but have been objected to because patients frequently neglect to remove the coating before inserting the suppository, and it does not melt or absorb, as intended. When dispensed with coatings, plain directions for the removal of the films should be affixed to the container and verbal instructions also given to the patient. Similar protection is afforded by wrapping the suppository in tinfoil or paraffin paper. It is generally preferred, however, to dispense such as need be protected from the air in tightly stoppered bottles or in...
