“Because the balls sent by this gun are not ordinary balls, but little cases of glass (invented by Leniebroek, an Austrian chemist), of which I have a large supply. These glass cases are covered with a case of steel, and weighted with a pellet of lead; they are real Leyden bottles, into which the electricity is forced to a very high tension. With the slightest shock they are discharged, and the animal, however strong it may be, falls dead. I must tell you that these cases are size number four, and that the charge for an ordinary gun would be ten.”

“I will argue no longer,” I replied, rising from the table; “I have nothing left me but to take my gun. At all events, I will go where you go.”

Captain Nemo then led me aft; and in passing before Ned’s and Conseil’s cabin, I called my two companions, who followed immediately. We then came to a kind of cell near the machinery-room, in which we were to put on our walking-dress.

CHAPTER XV
A WALK ON THE BOTTOM OF THE SEA

This cell was, to speak correctly, the arsenal and wardrobe of the Nautilus. A dozen diving apparatuses hung from the partition, waiting our use.

Ned Land, on seeing them, showed evident repugnance to dress himself in one.

“But, my worthy Ned, the forests of the Island of Crespo are nothing but submarine forests.”

“Good!” said the disappointed harpooner, who saw his dreams of fresh meat fade away. “And you, M. Aronnax, are you going to dress yourself in those clothes?”

“There is no alternative, Master Ned.”

“As you please, sir,” replied the harpooner, shrugging his shoulders; “but as for me, unless I am forced, I will never get into one.”
