Carwardine was an accurate anatomist and a fine operator. He was a skilled draughtsman, who illustrated his own writings. He also designed his own instruments, notably intestinal clamps; and while he was a clinical clerk he invented "Carwardine's saccharometer" for measuring sugar in the urine of diabetic patients, which was still obtainable from instrument-makers at the end of his life. He was interested in photography and music, and sang in choral societies in his younger days. Publications:- *Operative and practical Surgery*. Bristol: Wright, 1900.
