Are any of the mounts more jmrticularly developed on the Spatulate hand?

Yes: for instance, in a Spatulate hand, where the fingers are longer than the palm, Mercury is usually large, and there is a good amount of intuition, versatility, and scientific ability displayed in the character; but if the fingers are shorter than the palm Mars will generally be found full and the nature will be a bold and courageous one, fond of fields ports, agriculture, etc., but rather sensual.
