Much indebted for his paper on the influence of the solar spectrum on vegetable colors. Has a series of experiments ready that he hopes will resolve some of his own doubts. Does not like the term J. W. Draper uses for the new rays.

Much indebted for his paper on the influence of the solar spectrum on vegetable colors. Has a series of experiments ready that he hopes will resolve some of his own doubts. Does not like the term J. W. Draper uses for the new rays.
Sends a few samples of plates made by the cyanotype process; they are poor because the sun has not been very strong of late. Comments on this process and wishes JH would make a few experiments with his more perfect apparatus. Inclined to agree with him about the mechanism of the eye.
Should request Mr. Wildes to wait until JH gives his orders. Is gratified by JH's suggestions, but will not regret being passed over. Did not find Lady Herschel's letter at once for various business reasons.
Has just confirmed the Hawkhurst apportionment; comments on this. Encloses a copy of the notice.
Grateful for the account of Lady Herschel. Feels sorry for James Stewart; hopes to visit him later. Enjoyed himself in Holland; then went on to Germany, which he hopes to revisit when he has learned more of their language. Brother of Mrs. Jones has died.
Sending a description of the observatory he has erected, containing an equatorially mounted Newtonian reflector. Has high opinion of its efficiency. Has detected a sixth star near the trapezium of Orionis.
It is a long time since he thanked him for the assistance in becoming a member of the R.S.L. and the R.A.S. Doubtless his work at the Cape was a great success. Hoped to visit England again but seems improbable now. Sends J. F. Encke's memoir for the R.S.L., R.A.S. and JH. Is very interested in his memoir on the variable light of Orionis. C. F. Gauss continues his magnetism.
Not much is known about the circumstances that affect the color of plants. JH's researches will be valuable if they throw any light on the subject. Comments on the various theories affecting the color of plants.
Thinks it necessary to revise the instructions for the magnetic observations. Makes some suggestions for the Report of the Committee.
Has just received JH's circular. Was not fully aware of the labor involved in drawing up the Report of the Council. Needs a new edition of the part concerning the fixed observatories. Outlines method for new edition. Sabine should be responsible for the material on Magnetic Surveys.
Sending, care of Dr. Grant, the first part of a series of experiments on the magnetic influence of light, which appeared recently in the Calcutta Journal. Has been unable to obtain a characteristic specimen of Kankar in Bengal. Dr. Hugh Falconer is an expert on the Kankar in Bengal and he will try to obtain information from Falconer.
Received JH's constellation reform paper. Reports on triangulation at Zwartland and observations of possible variable stars. Obelisk at Feldhausen erected; relates controversies over the site.
Informs JH that the B.A.A.S. has place him on a committee to conduct experiments by capture balloon on the atmosphere.
Observations on double stars.
Informs JH that the B.A.A.S. has placed him on a committee to supervise the translation and publication of foreign scientific memoirs.
Would like JH to come to Manchester on 23-25 to give support for the Kew Observatory. F. W. Bessel and G. A. Erman are coming.
Sends a memoir he has scribbled off for next Wednesday's meeting. Would like JH's advice on several points.
Many thanks for JH's explanations, which gave satisfaction to the geologists. Gives two queries of his own for which he would like clarification. Can they print JH's Alpine phenomena memoir?
Pleased that JH can come on the occasion of F. W. Bessel's visit, as W. R. Hamilton, G. B. Airy, and Francis Baily cannot come. Comments regarding Foreign Orders.
Has only just received JH's parcel dispatched some six months ago, due to lack of transport during the winter months. JH's poem on the Old Telescope has been in great demand. Pass the enclosed to Miss Hamilton. Would like an autograph of JH for her album.
