No vessel ever left England with such a set of Chronometers, viz., twenty-four, all very good ones. In short, everything is well, and I have only now to pray for the sickness to moderate its fierceness, and I shall do very well. Yet I should not call it one of the very best opportunities for natural history that has ever occurred. The absolute want of room is an evil that nothing can surmount. I think L. Jenyns did very wisely in not coming, that is judging from my own feelings, for I am sure if I had left college some few years, or been those years older, I NEVER could have endured it. The officers (excepting the Captain) are like the freshest freshmen, that is in their manners, in everything else widely different. Remember me most kindly to him, and tell him if ever he dreams in the night of palm-trees, he may in the morning comfort himself with the assurance that the voyage would not have suited him. I am much obliged for your advice, de Mathematicis. I suspect when I am struggling with a triangle, I shall often wish myself in your room, and as for those wicked sulky surds, I do not know what I shall do without you to conjure them. My time passes away very pleasantly. I know one or two pleasant people, foremost of whom is Mr. Thunder-and-lightning Harris (William Snow Harris, the Electrician.), whom I dare say you have heard of. My chief employment is to go on board the "Beagle", and try to look as much like a sailor as I can. I have no evidence of having taken in man, woman or child. I am going to ask you to do one more commission, and I trust it will be the last. When I was in Cambridge, I wrote to Mr. Ash, asking him to send my College account to my father, after having subtracted about 30 pounds for my furniture. This he has forgotten to do, and my father has paid the bill, and I want to have the furniture-money transmitted to my father. Perhaps you would be kind enough to speak to Mr. Ash. I have cost my father so much money, I am quite ashamed of myself. I will write once again before sailing, and perhaps you will write to me before then. Remember me to Professor Sedgwick and Mr. Peacock. Believe me, yours affectionately, CHAS. DARWIN. CHARLES DARWIN TO J.S. HENSLOW. Devonport, December 3, 1831. My dear Henslow,
