Dear Sir

I turned a Snake loose into the yard with 2 of Grotes Porcupines, one of them shook his tail at the sight of the Snake, the other did not, but gnashed his teeth and appeared much inclined to bite the snake, I then tried the Crested Porcupine he did not shake his tail, but set his spines up and I thought he would attack the snake with his teeth1   he walked round the snake and appeared angry but did not touch it— I then put the Snake into the yard with the little Java Porcupine2 but he was evidently frightened of the snake and kept as far from it as possible but did not rattle his tail. I believe from what I saw that the Porcupine if hungry and in a wild state met with a snake he would kill and eat it,

Yours faithfully | A D Bartlett

Chas. Darwin Esq.


See letter to Francis Darwin, 13 May [1872]. In Expression, p. 93, CD reported that one porcupine rattled its quills and shook its tail when a snake was placed in its enclosure. Grote’s porcupine (Hystrix grotei) is now H. brachyura (the Malayan porcupine). The crested porcupine is H. cristata.
The Java porcupine is now known as the Sunda porcupine (Hystrix javanica).


Reports aggressive reactions of three kinds of porcupines to a snake, concluding that in the wild they would probably kill and eat it [see Expression, pp. 93–4]
