3. In summer when the sun is most effective, it is sufficient if the above-mentioned little milk sugar globules are exposed to the sun for 1 month. However, they may not be exposed to the sun all the time while it is visible in the firmament, but only for as long as the sun is still standing at an angle of 45 degrees. Below that, because of the low angle of the rays, their light and impact is too weak and has little or no effect at all upon the globules. Therefore, they must be carefully covered with the described lid and kept in a cool dry place until the next day.
4. To store these sunlight impregnated globules you must get little bottles made from dark-violet glass, made airtight with a clean stopper from the same glass, only then can they be well sealed by means of a bladder (plastic today). They must be kept in a cool and dry place.
