From William Aitchison to George Cupples 30 June 1869
Linhope
30th June | 1869
Dear Sir
In reply to yours of the 28th I have to express my regret that I have not been more explicit in my enumerations—1
The 33 convey scores which amount to 660 Lambs & the 30.8 to 608 Lambs & which will give an explanation of all the figures I have sent you—
I note what you say about Mr Elliot’ opinion but my long experience has brought me to an opposite conclusion, for every year at the time of castration (about the 22d May) I have had more female than male Lambs, which is no doubt partly balanced by Tup Lambs being more liable to die after birth—2
I am Dear Sir | Y’rs faithfully | Wm Aitchison

Summary
WA explains the figures he sent GC. In his experience female lambs at the time of castration outnumber the males. [Robert] Elliot differs.
