An exceedingly practical chapter on ambulance is added in 

 the Victorian forthcoming book, and I can testify, from prac- 

 tical experience, to the deep interest children take in this 

 subject. 



I see in this movement hope for the future of sanitary 

 work. It may, no doubt, take years to leaven the public 

 mind, but, now that sanitary reformers have been able, in 

 many communities, to overtake the cruder insanitary condi- 

 tions by legislation, by dint of this further movement of in- 

 structing the young we may secure that additional hold whicli 

 will not only do away with the constant struggle that now 

 goes on between sanitary enactments and the fulfilment of 

 their requirements by the people, but also bring about what 

 we all so much desire to see — the people of themselves, either 

 by legislation or otherwise, aiming to secure a higher sanitary 

 condition for its own sake.
