Dear Sir

I am sorry to cause you trouble, but I sh^d. greatly prefer an enema with shorter nozzle, viz 2 inches or 2 inches & $\frac{1}{4}$, measured from the top of the ivory collar to the extremity of the nozzle.— I find also I sh^d. like the whole enema a little larger, viz about $\frac{1}{4}$ of an inch higher, but if you have none such, the size of the one returned would do.—²

Dear Sir | yours faithfully | Ch. Darwin
