Dear Sir

I am quite delighted in at last being able to tell you that your Box with the fossil cirripedes has arrived quite safely this morning.—¹ It is a great load off my mind.— Not one specimen is injured, except, perhaps, some of the valves of your Anat(?) cretæ.—² It is a noble collection, & I feel most grateful to you for having entrusted them to me.— I have now a great many collections in this house, so that I have good means of comparison.— Most of your species, as far as a hasty first glance tells, are different from the British. Your P. medius. is the same as P. sulcatus of Sowerby; & instead of being a Pollicipes, it is a Scalpellum, though these genera differ much too little.—³ The P. elegans I have (unnamed) from our Chalk.—⁴ I will do my best in comparing all the specimens which I have now together; but I am not hopeful of producing good results: I much dislike giving specific names to each separate valve, & thereby almost certainly making three or four nominal species for each true species.—

I am extremely pleased to see the Alepas.⁵ The cause of the great delay was in Prof. Forchhammer having sent the box within another to a dealer in minerals, who uncourteously did not take the trouble to inform me. Please to tell Prof. Forchammer that owing to his note I have got the Box, & pray give him, & accept yourself my most cordial thanks.— I will take great care of your specimens.— I hope now that this Box has arrived safely, that you will add to your already great kindness, & send me the northern species alluded to in your former letter.—

I will hereafter write again to you.—

Pray believe me | my dear Sir | Yours most gratefully | C. Darwin
