H. F. and CONAMARA.--Write to Griffith and Farran, St. Paul's-churchyard, E.C., for a small shilling manual called a "Directory of Girls' Clubs," which will give you a large choice of educational, literary, industrial, artistic, and religious societies instituted for the benefit of girls, the cost being little more than nominal. M. HEDGE.--The change of your address, from what has been given in the "Directory of Girls' Clubs," will probably cause you inconvenience, which it is now too late to avoid. You should have named the probability of a change. In any case, we can tell our readers that those who wish to avail themselves of your useful Society for Studying Languages, should address the secretary at Lyndhurst Lodge, Chelsea-road, Southsea, Hants. A. G. O. E.--We scarcely think that any system for helping the memory for ordinary use would be of service to you in the matter of playing long pieces of music by heart; it is so much a mechanical operation, the hands often acting while the mind is preoccupied with other matters. Try to learn a simple air, not a long piece of six pages. A SWISS GIRL.--The Cambridge and Oxford examinations are open to students of all nationalities alike. For information respecting those of either university, write direct. If you wish to compete in the Cambridge junior local examination, held in December, you must be under seventeen. Write to the Rev. G. F. Browne, St. Catherine's College; fee, L1. For the Cambridge senior you must be under eighteen. The Cambridge higher (local) examinations are held in December and in June; fees, L1 and L2. An honour certificate in this examination admits to Tripos examinations the members of Girton and Newnham who have resided during a sufficient number of terms, provided the student has passed a language and mathematics. If your age should exclude you, you might go to the universities of Edinburgh, Glasgow, or St. Andrews, where no limitations are made in respect to age. GUESS.--We advise you to write to the British chaplain of the Embassy Chapel, in the Rue d'Aguesseau, for information and the best advice, as he has taken a special interest in the matter of English girls being sent to French schools, and has publicly addressed the question in all its many bearings. Address the British Chaplain. ANXIOUS MOTHER.--See our answer to "Guess." There is a French Protestant institution, directed by Madame Yeatman Monoury, 27, Bd. Eugene, Parc de Neuilly, Paris, which is, or was, patronised by the Rev. Canon Fleming, the late Bishop of Carlisle, Bishop of Down, Lord Napier of Magdala, and other persons of consideration. There is also a Protestant school at 27, Rue des Bois, pres du Bois de Boulogne, for which the charge amounts to L60 per annum. Apply to the lady directress, Mademoiselle Jonte. ART. A COLONIAL SUBJECT.--The illuminating body mentioned is used on parchment and hot-pressed drawing-paper. It is mixed with the water-colours to render them opaque.
