once (or at most twice) during the journey, so as to 

 keep the water up to the top ; and the can swung 

 easily and steadily all the way to London, with the

 have been killed from the incessant jolting. 



In the course of our transmissions one lot only 

 was spoilt, and that was spoilt, I believe, by the 

 bottom of the can not being firm enough. It cockled 

 and buckled at every swing from the weight of water 

 in it, thus keeping the mass of ova within in one

 would hold about a gallon, and were shaped like 

 oil-Cans, with handles on either side to swing them 

 by. The cork was perforated, and through it was 

 pushed a very small but long-tubed funnei. This 

 supplied air to the water, prevented splashing, and
