Apart from joking, however, this is not such a great matter, and it is the only thing I would see altered in the whole affair.  The officers, as far as I have seen them, are a very gentlemanly, excellent set of men, and considering we are to be together for four or five years, that is a matter of no small importance.  I am not given to be sanguine, but I confess I expect a good deal to arise out of this appointment.  In the first place, surveying ships are totally different from the ordinary run of men-of-war.  The requisite discipline is kept up, but not in the martinet style.  Less form is observed.  From the men who are appointed having more or less scientific turns, they have more respect for one another than that given by mere position in the service, and hence that position is less taken advantage of.  They are brought more into contact, and hence those engaged in the surveying service almost proverbially stick by one another.  To me, whose interest in the service is almost all to be made, this is a matter of no small importance.

Then again, in a surveying ship you can work.  In an ordinary frigate if a fellow has the talents of all the scientific men from Archimedes downwards compressed into his own peculiar skull they are all lost.  Even if it were possible to study in a midshipmen’s berth, you have not room in your “chat” for more than a dozen books.  But in the “Rattlesnake” the whole poop is to be converted into a large chart-room with bookshelves and tables and plenty of light.  There I may read, draw, or microscopise at pleasure, and as to books, I have a carte blanche from the Captain to take as many as I please, of which permission we shall avail ourself—­rather—­and besides all this, from the peculiar way in which I obtained this appointment, I shall have a much wider swing than assistant surgeons in general get.  I can see clearly that certain branches of the natural history work will fall into my hands if I manage properly through Sir John Richardson, who has shown himself a very kind friend all throughout, and also through Captain Stanley I have been introduced to several eminent zoologists—­to Owen and Gray and Forbes of King’s College.  From all these men much is to be learnt which becomes peculiarly my own, and can of course only be used and applied by me.  From Forbes especially I have learned and shall learn much with respect to dredging operations (which bear on many of the most interesting points of zoology).  In consequence of this I may very likely be entrusted with the carrying of them out, and all that is so much the more towards my opportunities.  Again, I have learnt the calotype process for the express purpose of managing the calotype apparatus, for which Captain Stanley has applied to the Government.

And having once for all enumerated all these meaner prospects of mere personal advancement, I must confess I do glory in the prospect of being able to give myself up to my own favourite pursuits without thereby neglecting the proper duties of life.  And then perhaps by the following of my favourite motto:—­
