    said, but is affected with an incapacity to employ substantives, having lost the memory of words as far as that part of speech is concerned, and he will make use of a periphrasis to avoid using the substantive required.” A few months afterwards he became para- lysed, and soon after that so demented as to necessitate his removal to the Borough Asylum. This, in its first stage, seems to have been a case of Aphasia pure and simple. Trousseau records several instances in which such a condition lasted only a few days or perhaps only a few hours, owing to the existence of some temporary abnormal cerebral condition—induced occasionally without apparent cause, and at other times as a sequence of some great excitement conjoined with ‘worry’ or over-work. Such cases are not extremely rare; two or three of them have also fallen under the notice of the writer. When however an actual lesion exists, of greater mag- nitude than that which may have been present in the first stage of Dr. Bateman’s case, it often happens that the Aphasia co-exists with a paralysis of the right side of the body—or a right Hemiplegia, as it is termed. The larger the lesion, too, the greater is the chance that the Visual or the Auditory Centres themselves, or some of their commissures may be seriously damaged: with the effect of producing an admixture of Amnesic symptoms with those of Aphasia. Such additional symp- toms may reveal themselves either from the first, or only as the individual begins to recover from the Aphasic condition. Three instances of complications of this sort will now be given. The first of them being a case recorded by Trousseau, in which Aphasia was produced by a lesion that, at the same time, caused right-sided paralysis together with inability to read—the latter disability being prob- ably due to damage of the left Visual Word-Centre.
