Heath is generally cut every six years, often in order to provide young growth for grazing. Also, the heath is in good condition for burning at six years growth.

Will be grateful for facts from Mr Linton on numbers of eggs from goldfinch–canary crosses.
Translates some German terms describing colour of horses.
Returns polar maps. Advises on methods of map projection, favoring polar projection. Working on new maps.
Thanks AG for 2d part of "Statistics [of the flora of the northern U. S.", Am. J. Sci. 2d ser. 22 (1856): 204–32; 2d ser. 23 (1857): 62–84, 369–403].
Is glad AG concludes species of large genera are wide-ranging, but is "riled" that he thinks the line of connection of alpine plants is through Greenland. Mentions comparisons of ranges worth investigating.
Believes trees show a tendency toward separation of the sexes and wonders if U. S. species bear this out. Asks which genera are protean in U. S.
Discusses his itinerary for the British Isles. Gives address where he may be reached. Wishes to visit JH at Collingwood. Congratulates JH on his improved health.

JDH thanks Asa Gray for his letter & review of [Rev. Miles Joseph] Berkeley. Berkeley will not like Gray's review or JDH's in JOURNAL OF BOTANY. JDH comments on Gray's criticism of his ideas on physiology, comparing them to a firework, and to his own less ordered style of critique. Declares that he will not take account of a 'vital force' until anyone else does. Compares American & British terminology i.e. in the United States physiology is synonymous with biology. Discusses nomenclature & the use of the English 'anth' in names such as Ranunculanths, compared to using the suffixes: 'ads' or 'worts' in place of aceae. This was started by [John Stevens] Henslow & despite misgivings JDH has advised [George] Bentham to retain them as they are now effectively sanctioned by the government; being used in the National Schools. He asks Gray not to deter Bentham from using the system as it is the current vogue & it is hard enough to get government to publish such books for the amateur, & this class of people cares a great deal about terminology. JDH thinks [John] Lindley is correct to refer Podostemons to near Lentibulariaceae though he previously thought their place was with Scrophulariaceae.

All is well. Hope JH hears 'good accounts from India.'
Sends a copy of his Astronomical Investigations. Claims there is an 'inequality in the motions of Mars and the Earth.'
Sends information concerning India in response to letter of JH's son. [Sir Charles Edward] Trevelyan has printed such information occasionally. Many do not see the importance of India.
Sexes of algae.
Congratulations [on Mrs H’s delivery].
Balanus balanoides positively identified by CD.

J. C. Symons is spreading locally false theories about the rotation of the moon. Would like JH's views on this.
Thanks for information, which is just the amount he wanted.
Will not go to the BAAS meeting in Dublin: the frightful voyage deters him.
