deserves particular notice. This he effected by letting 

 them drop by their threads into scalding water, and 

 suddenly withdrawing them ; for by this means the 

 epidermis peeled off very easily ; and when this was 

 done he put them into distilled vinegar and spirit of 

 wine mixed together in equal proportions, which, by 

 giving a proper firmness to the parts, afforded an oppor- 

 tunity of separating them, with very little trouble, from 

 the exuviae, or skins, without any danger to the parts ; 

 so that by this contrivance the pupa could be shewn to 

 be wrapped up in the caterpillar, and the butterfly in the 

 pupa. Those who look into the works of Swammerdam 

 will be abundantly gratified, whether they consider his 

 immense labour and unremitting ardour in these pursuits, 

 or his wonderful devotion and piety. On one hand, his 

 genius urged him to examine the miracles of the great 

 Creator in his natural productions ; while on the other, 

 the love of that same All-perfect Being, rooted in his 

 mind, struggled hard to persuade him that God alone, 

 and not His creatures, was worthy of his researches, 

 love, and attention.
