A SHORT time ago the Institution lent to the head mistress of an infants' school in a very poor part of London, one of its models in glass tanks, which are used for showing how a self-righting Life- boat empties herself of water and rights herself when capsized. These models are much used by our lecturers,especially when lecturing to schools, and always prove attractive. The head mistress asked to be allowed to keep it for a week, and when she returned it she wrote: " The children were delighted with it, and hope you will lend it to them again next year. We made a collection for the Life-boat fund, for which I enclose cheque for 15s. It is a small amount, but our school is very, very poor.".
