浸制、干制和压删、剥删的标本,以前我们用的很多,但总因时间稍久就会变色、变形或剥落而感到遗憾。这次我们由于见到一个琥珀而受到启发,就大胆试制了一种“晶制标本”(姑妄名之)。我们先把动物标本放在一个盒子里,随即倒进糖浆似的融熔的松脂(即松香),很快就冷凝了,脱去盒子,就是一块透明而略黄的标本,小虫儿象冬眠在里面一样,毫毛都看得清楚,姿势也很自然。为了使晶体标本透明而又无色,所以后来我们又改用白明胶和水玻璃做材料,试验的效果也很理想。 Baptist, dried and pressed delete, stripped of specimens, we used a lot before, but always a little time will change color, deformation or peeling and regret. This time we were inspired by seeing amber, we dared to experiment with a “crystal specimen” (Guyou name). We first put the animal specimens in a box, and then poured into a syrupy melted rosin (rosin), quickly condensed, off the box, is a transparent and slightly yellow specimens, worms like hibernation In the same, the hair is clearly visible, the posture is very natural. In order to make crystal specimens transparent and colorless, so later we use gelatin and water glass material, the test results are satisfactory.
