Is grateful for the very interesting photograph; will keep the preparation secret if he discovers it. Has been trying many experiments with benzoates with curious results, but bad weather has stopped progress so has now turned to thermography to test the truth of Mr. Prater's conclusions. Comments on these.

Enclosing the specimens of photographs by different methods; comments on the methods used. Encloses a paper by Were Fox.

Enclosing specimens of his chromatype; comments on how these were produced and their characteristics. Is very busy with the Annual Exhibition of the Polytechnic Society.

Has received from the P.M. proof of an article replying to the attack of [L. F.] Moser on RH, also details of a new instrument by J. W. Draper. Would like JH's opinion on the instrument. Has had some good results with the fluorates recently.

Would like his views on a name for the combination of hydrogen and chlorine. Comments on the various theories. Has replied to [L. F.] Moser.

Has just received the news that Hartnell's son has passed the exams at Trinity College, Cambridge.

Sending a copy of the English Universities. Has quoted JH in the third volume. Hopes that university reform will be a popular topic.

Is pleased JH has such a high opinion of the new work on the English universities; it has hardly been noticed by the public. V. A. Huber belongs to the Conservative party but tries to be impartial as a historian. Hopes that the amount of reading at universities will be reduced.

Is much obliged for letter and pretty specimen of English hexameters. Is sad that there has been no success with the classical hexameter in our language. Comments on its use.

Sending some pages from the Mechanics Magazine containing details of clock escapements, superior to those at present in use.

Will find one friend at the R.S.L. Club dinner next Thursday.

May he submit JH's name as a candidate for the Honorary membership of the Literary Society; gives list of the other candidates.

Met JH when he was residing in the Auvergnes. Since then he has had to leave France and now resides in England, where he is making a living teaching French and writing books. Would be grateful if he could add JH's name as a subscriber to a forthcoming work.

Wishes JH had added his name at the head of the list of subscribers. Thinks he is being too cautious. AJ is responsible for the whole of the work though it appears under two authors.

Invitation from the Local Council to visit Cork for the B.A.A.S. meeting.

Sends a paper of his brother, Christopher Kemplay, on a theory respecting comets. Has already submitted it to James Challis, who objects to some points. Would be glad of JH's comments.

Sending a letter he has received from a friend regarding a curious observation of the moon. Has seen the comet and encloses diagrams of its position.

Has just heard that JH would like some deodar seeds; so he encloses some. Could also supply some young plants if he would like them.

Twelve deodar plants are being dispatched by coach. If JH plants the seeds now he should have nice young plants by the autumn. Would be obliged for his paper on vegetable photography.

President of the Società Italienne des Sciences has received the invitation for members to attend the B.A.A.S. meeting at Cork. Regrets the length of the journey prevents members attending, but have nominated Michael Faraday to attend.
