Exactly the same techniques can be used for handbook tissue processing. Soften the paraffin within an oven at 60°C in glass containers. Immerse the specimens into the melted paraffin.
When we adopted his protocol faithfully, the tissue was improperly infiltrated as well as sections mainly torn and unusable. Only after we additional an infiltration stage with molten paraffin to His’s protocol have been the sections of suitable quality.

Also, great photography in the gross specimen is necessary with apparent demarcations as to the place specimens are attained for diagnostic examination and for ancillary studies.
