I heard yesterday to my joy that Dr. Hildebrand has been experimenting on the direct action of pollen on the mother-plant with success. He has also succeeded in making a true graft-hybrid between two varieties of potatoes, in which I failed. I look at this as splendid for pangenesis, as being strong evidence that bud-reproduction and seminal reproduction do not essentially differ.英文原著 · 《More Letters of Charles Darwin Volume I》
From animals are drawn good burning lights, and good medicines against burning. Though the seminal humour seems of a contrary nature to fire, yet the body completed proves a combustible lump, wherein fire finds flame even from bones, and some fuel almost from all parts; though the metropolis of humidity+ seems least disposed unto it, which might render the skulls of these urns less burned than other bones. But all flies or sinks before fire almost in all bodies: when the com- mon ligament is dissolved, the attenuable parts ascend, the rest subside in coal, calx, or ashes.英文原著 · 《Religio Medici》
